OCATT Therapist Biographies

Michelle Hogeterp, RP, RMFT

Opening OCATT is the fulfillment of a dream that I have had for several years. I specialize in Adoption, trauma and attachment. I have a Masters degree in Counselling from Tyndale University College and Seminary and an honours degree in Psychology from Redeemer University College. I am a registered psychotherapist with the college of registered psychotherapists of Ontario (Registration number: 001761). I am also a certified Dyadic Developmental Psychotherapy Practitioner and Consultant. I work from a trauma informed, attachment-focused perspective – drawing primarily from her training in Dyadic Developmental Psychotherapy, Theraplay, EMDR and SMART (Sensory Motor Affect Regulation Training.)

Now, with all that serious stuff out of the way, here’s a little bit about the real me: I’ve taken a rich and interesting road to where I am today. Early in my post university years I worked with children in a social work context. When our child care bills got higher than my social work salary I took the step to remain home with our growing family. Today we have three awesome but imperfect kids that I learn from every day! During the time of my domestic career, I also taught a group music program to kids age 3-11. I loved the energy and enthusiasm of the kids and their music. As our kids made the transition to school I decided to go back to school to build on my compassionate nature in a counselling degree. I loved the learning and the challenge of a counselling education.

Beside career and family stuff I like to have fun: my family has dragged me out camping and canoeing enough times that I’m starting to enjoy it (except for rain and bugs!). I enjoy exploring new places. I love playing the piano and singing – and have played in bands for years with my drummer husband. I enjoy a hearty laugh and times away with close friends. And in the quiet times I love a cuppa tea and a good book. These good things and a deep faith journey are the ground of blessing beneath my feet in the twists and turns of life.

Tanya Eichler, MCP, CCC
Before joining OCATT, I have been in private practice – Strategies Counselling and Consulting -, in Kemptville. I have also, until recently, been working for Citizen Advocacy’s Fetal Alcohol Resource Program as an FASD Coordinator, training people about FASD. I completed my Masters Degree in Counselling Psychology at Adler University in Vancouver, BC. I have completed my second level of Dyadic Developmental Psychotherapy training and have focused on trauma-informed practice that includes understanding the brain and stress response system’s reaction to stress and trauma. I am supervised by Dr. J. Robert Groves, Ph.D. (CPO Certificate # 805) and am certified with the Canadian Counselling and Psychotherapy Association.

While I wanted to work as a therapist many years ago, the journey here has not been direct. After completing my undergrad degree in BC, I gathered a great deal of experience supporting families with children with special needs; families involved in the child protection system, and families struggling with addiction and complex stress. After starting a family of my own, I began my counselling degree and,ended up working as an FASD (Fetal Alcohol Spectrum Disorder) Key Worker for the practicum portion of my degree, I. This experience taught me a great deal about supporting families in crisis, trauma work and the creativity needed when working with people who process information differently.

I have learned that many of the challenges we face are rooted in relationship struggles. My practice is based on attachment theory with a focus on using sensory strategies to create felt safety. I work primarily with adoptive and foster families, and people struggling with ADHD and anxiety. Often people come to counselling because there has been a significant or unexpected life event and they need understanding support as they walk through the event.

My personal style tends to be relaxed and, while I understand emotional pain and stress, I often rely on humour as a source of resilience. I draw on my own life experiences of adoption, parenting, family and health stressors and life challenges as well as my training as I seek to walk alongside my clients as they gain perspective on their own situations through the therapeutic experience. I believe that therapy has to be a “good fit” and am very comfortable making sure that all of my clients find the best fit for their needs, either in my practice or with another therapist.

Coriander Stevens, MA, RP

I work collaboratively with children, families, couples, and individuals in therapy. I believe that my role as a therapist is to journey with clients, join in whatever is going on, and then help the client figure out where we need to go. I work experientially with clients, exploring the responses that come up in session so we can become more aware of who we are.

I am passionate about attachment and relationships. Our lives are shaped by our relationships, making it essential to understand the impact these relationships have on us. Attachment therapy helps make sense of what happens in ordinary life and the importance of focusing on connection. At young ages each one of us develops an attachment style that can impact the way we cope, relate to others, and live our lives. Attachment styles and bonds can be damaged by trauma, but also healed through secure relationships. I provide a warm, playful and safe environment to help my clients develop coping skills, self-understanding, and secure relationships.

I have an M.A. from Saint Paul University in Counselling and Spirituality with a specialization in couple and family therapy and an Honours B.A. in Psychology from Redeemer University College. I have continued my education in attachment through training in Dyadic Developmental Psychotherapy (DDP). This training further qualifies me to work with children and families. I am being supervised by Dr. J. Robert Groves (CPO #805), who has extensive training in attachment and developmental psychology. I am also supervised by Michelle Hogeterp, who is a certified DDP consultant. I am a member of the College of Registered Psychotherapists of Ontario (#007660).

Allison Grey, RP

I began my journey working with children and youth over 20 years ago in the field of Child and Youth work.  My passion for working with children and youth led me to further my education and pursue a Bachelor of Arts with a Specialization in Psychology. This has allowed me to expand my work with children, youth and families as a Registered Psychotherapist.  My experience and passion are in helping people build and strengthen healthy attachments and connections not only with others, but with themselves. 

I have an extensive history of working with children, youth, parents, and families using an attachment-based framework.  I was trained in Dyadic Developmental Psychotherapy (DDP), an attachment-based therapy. It is truly an honour to bear witness to the changes that occur when focused on relationship and connection. 

In my work I use other evidence-based approaches including, Narrative Therapy, Cognitive Behavioural Therapy, Solution Focused therapy, Motivational Interviewing as well as Mindfulness.  I specialize in attachment, trauma, depression, anxiety, addictions, ADHD, and children in care, and adoption with children, teens and families.

I believe that connection within the therapeutic relationship is so important and I will work with you in order to create safety as you trust me to walk alongside you for a part of your journey. I will focus on your story in a respectful and non-judgmental way so that together we can create the foundation for what you need in order to grow and change in the ways you want.

During difficult or challenging times, there is an opportunity for deeper learning, awareness and capacity to connect in more meaningful ways. We all have within us the capability to heal, to grow, and find true connection with ourselves and with others.      

Mélanie Martel, MSW RSW

My name is Mélanie Martel. To most, I’m Mel. I have been offering bilingual (English, français) psychotherapy and counselling services since 2011. I hold a Masters degree in Social Work as well as an honours degree in Psychology from the University of Ottawa. I am a member, in good standing, of the Ontario College of Social Workers and Social Service Workers (OCSWSSW, #819592) since 2010. I work from an attachment-centered, trauma-informed lens. I use an integrative approach, drawing on dyadic developmental psychotherapy (DDP; levels I and II), dialectical behavioural therapy (DBT) and narrative therapy. I receive clinical supervision from Psychologist Dr. Queenie Lo.

As a therapist, my style is relaxed, fluid and intuitive. I have the privilege of walking alongside children, youth and adults individually and I also work with parents and families. I genuinely and whole-heartedly believe in taking a collaborative approach to therapy and strive to establish a compassionate, non-judgemental, and person-centered environment. A little humour and playfulness also helps to bring a human touch!

I sincerely believe that everyone is doing the best that they can with what they know. Behind every problematic behaviour, recurring relational cycle or pattern, there’s a story. These are often stories of pain, resilience and adaptation. Left unchecked, they shape and influence our behaviour in the now, and within our relationships. In my experience, having our stories witnessed is a powerful way to disempower their hold on us.  Some of people’s deepest wounds have come at the hands of painful relationships. Conversely, relationships also hold the power of our most profound healing. We are wired to seek belonging. Learning to foster safe, authentic and attuned connections with those around us brings so much depth and richness to our lived experience.

Another guiding philosophy to my work is that when we know more about the inner workings of our bodies and minds, we experience much less of the crippling shame which keeps us feeling stuck, in pain, and alone. It is very important to include the body in the therapeutic experience.

On the personal side of things, I wear many hats. I am daughter to beautifully imperfect and loving parents. I am a sister to many, biologically and of my choosing. I am a partner to one very patient and compassionate human! I am also a mother to two affectionate, intuitive and perfectly imperfect children that can have me both crying and laughing mere minutes apart! I am both confident and proud of the woman I am today, while also being grateful to always be learning, shifting, evolving and deepening. I am at my most regulated when I am with my people, playing, creating, cuddling, and laughing. On my own, my most peaceful and refueling moments tend to happen on nature walks, while swimming or biking, and holding a paintbrush.

“The truest, most beautiful life never promises to be an easy one. We need to let go of the lie that it’s supposed to be.” – Glennon Doyle

Kathryn Flynn, RP (Q)

Hi! I’m Kathryn. I’m a Registered Psychotherapist (Qualifying) and a member of the College of Registered Psychotherapists of Ontario (#011095). Before pursuing a degree in counselling psychology, I’ve been a yoga, meditation and Ayurveda educator for over 12 years, with more certifications than we should bother listing here and a couple of other university degrees, too. I like learning – a lot!

I integrate different therapy approaches tailored to the client, but usually through an attachment-theory, trauma-informed lens. Drawing on dyadic developmental psychotherapy (DDP), compassion-focused therapy (CFT), Brainspotting, body-mind practices, and elements of cognitive-behavioural therapy (CBT), I help clients work through past experiences and present challenges. People describe me as warm, funny, and intelligent.

I didn’t go into psychology earlier in my journey because I had the idea that psychology was about what was wrong with people, and that didn’t feel compelling. If someone had re-framed it as psychology is about relationships – with ourselves, others, our minds, and beyond – I might have got here earlier! Creating an accepting, compassionate relationship as a container for inquiry and understanding has been transformative in my life, and I’m privileged to make it my work.

Beyond the office, I’m a mama to a super funny and active little kid, love learning about wine, exercising, spending time with friends and family, and being outside. (As a Toronto transplant, I’m not outdoorsy, more like an indoorsy-moved-outside way!)

Melissa Thivierge, RP

I began my journey as a counsellor working as a Child and Youth Counsellor 10 years ago and in doing so, discovered my passion for walking alongside people through their successes and life challenges. This discovery led me to pursue a B.A in psychology from Carleton University and a master’s degree in Counselling Psychology from the University of Ottawa. 

I am an integrative practitioner, rooted in attachment theory. While working from an attachment and holistic lens, I integrate other evidence-based approaches into my work with children, youth, adults, and families depending on the specific needs of each person – these include: Narrative therapy, Art Therapy, Dyadic Developmental Psychotherapy, Internal Family Systems, Cognitive Behavioural Therapy, Brainspotting, Family Systems Trauma Therapy, and Acceptance and Commitment Therapy.  I specialize in attachment disruptions, adoption support and children in care, trauma, ADHD, anxiety, depression, and family support. 

Kim Cluff, M. Ed RP

Hi, I’m Kim. I am a registered psychotherapist who has worked in the field of mental health for the past 25 years.  I am currently working with people who want to find ways to better cope with strong emotions, complex trauma, mood disorders and build stronger connections in their relationships. 

I have a long history of working with children, teenagers and young adults.  I am often described as conversational, humorous and creative in my approach. I believe in being transparent, flexible, nonjudgmental and creating safe spaces where people feel heard and connected. 

Over the years I have been trained in many approaches. I have special interests in Attachment based work, Dyadic Developmental Psychotherapy (DDP), Dialectical Behaviour Therapy (DBT), Trauma Focused CBT, Applied Polyvagal Theory and Narrative and Collaborative approaches. I am also building skills in Somatic and Psychosensory work which in part, comes from my own experience of the impact of trauma and stress on the body. 

On the personal side, I am a single mom of two sensitive, spirited and hilarious  humans.  We share our home with 3 cats and a dog which makes life very interesting on a daily basis. You will often find me reading, making art or enjoying a cup of coffee on my dock.

Heather Hodgins-Chan, OT Reg. (Ont)

Working with children has been a passion of mine for so many years. I am a registered occupational therapist in the province of Ontario and graduated from McGill University in 1999. Learning about the brain and body connection has always been fascinating to me; I also completed a degree in Anatomy and Cell Biology prior to studying Occupational Therapy. After many years of working in hospitals, a rehabilitation center and various schools, an unexpected dream of mine came to fruition in 2016 when I opened On the Ball Pediatric Physio and Occupational Therapy in Kanata with my physiotherapy colleagues. It has been my honor to work with so many wonderful children, families, caregivers, and professionals.

I’ve travelled extensively in the United States to further my training in Sensory Integration, Trauma-informed care, and use hands-on techniques, activities, and games that are fun and rewarding for children to develop and strengthen the nervous system. I’ve become a “behavioral detective” and address the underlying reasons for difficulties with self-regulation. Occupational Therapists help people to become independent in their daily activities or “occupations”. Sometimes this may mean that an overactive nervous system can affect learning, interacting with others, or being able to focus on self-care activities. Children need to feel safe and connected to be able to self-regulate. I’ve enjoyed participating in joint sessions with the psychotherapists at OCATT. I help to organize the nervous system by working on the body and to provide sensory-motor interventions; this allows the child to express themselves more openly with their psychotherapist. It has brought therapy to the next level!

Post-professional training has included:

  • Sensory Integration
  •  Psychosensory Interventions
  • Trauma-Informed Occupational Therapy
  • Safe and Sound Protocol from Integrated Listening Systems
  • Auditory Focus Program from Integrated Listening Systems
  • Rhythmic Movement Levels 1 and 2 and Face the Fear Reflex Integration Courses
  • Greenspan Floortime Approach
  • Praxis : Sensory-Motor Learning / Coordination Challenges
  • SOS (Sequential Oral-Sensory Approach to Feeding)
  • Misophonia
  • Attachment and Trauma / Polyvagal Theory
  • Design of at-home / school sensory spaces

When I am not working, I can be found outside tending to my flower garden, swimming, doing Pilates or driving my teenagers to soccer games. I hope to someday bring our one-year-old mini-Goldendoodle, Furley, to work with me.

Amanda Roi, OT Reg (Ont)

I am a registered occupational therapist in the province of Ontario and graduated from Queen’s University in 2018. I have always had an innate desire to work with children as I find their resilience, creativity and compassion never ending and inspiring. My passion for working with mental health has heightened as I continue to incorporate knowledge regarding the brain and body connection. I wholeheartedly believe that children are meant to thrive; I feel truly fortunate that my work allows me to embody and support these children and their families.

Ultimately, Occupational Therapists (OTs) utilize a holistic, client-centered and FUNCTIONAL approach to help clients and their families meet their individualized goals. Our OT training in the physical, psychological, social, emotional and environmental fields allows us to utilize a very functional and well-rounded approach to overall wellness.

I currently work as an occupational therapist at On the Ball Pediatric Physio and Occupational Therapy, and I am so pleased to have the opportunity to collaborate with the astounding team here at OCATT. In my experience, Occupational Therapy (OT) services are a key resource to add to a child’s support team – by helping children to regulate their nervous systems, incorporating both brain and body approaches, OT allows individuals to be recognized in their many facets, while complimenting additional professions such as psychotherapy!

Training has included:

  • Bachelor of Arts in Psychology with Honours, Carleton University
  • Master of Science in Occupational Therapy, Queen’s University
  • Psycho-Sensory Processing Intervention
  • Safe and Sound Protocol from Integrated Listening Systems
  • Currently enrolled in: Neurological Approaches for Self-Regulation: for kids with Autism, ADHD and Sensory Disorders

When I am not working, I can be found soaking up nature, practicing painting, listening to or creating music, and sharing moments with loved ones (including all our family pets!)
