I am a registered psychotherapist with the College of Registered Psychotherapists of Ontario (CRPO) and a registered social worker with the Ontario College of Social Work and Social Service Workers (OCSWSSW). I have worked for many years in a hospital outpatient community mental health clinic. I opened my private practice in 2018 and it has been going strong ever since.

Psychotherapy and Supervision

My clinical practice has expanded, and I am pleased to offer you the opportunity to work with some amazing clinicians. Our personal approach in psychotherapy is based on your needs, struggles and stressors. We do not believe in simply offering one method of treatment for all problems.  The clinicians that are now part of Advocating Hope will reflect the same approach and treatment.

The clinicians have completed training for a variety of styles of treatment, including Mindfulness, Dialectical Behavioral Therapy, Motivational Interviewing, Cognitive Behaviour Therapy, Narrative and Interpersonal Therapy. I am a resource to these clinicians and together we will explore your needs to embark on a healing journey of personal growth and improved mental-wellness. I will personally continue to support clients who access services through NIHB.


I been qualified through Behaviour Tech Intensive Training to offer Dialectical Behaviour Therapy (DBT).  The foundation of DBT is Cognitive Behavior Therapy, Behavior Therapy and Mindfulness.  My team have been trained in this approach as well. Many of us have training in numerous other forms of treatment including Emotionally Focused Therapy (EFT), Marital (Gottman), PACT,  Narrative, Solution Focused, etc.  I have included my CV if you are interested in knowing more.

Many of our clients struggle with Trauma, Borderline Personality Disorder (BPD), Anxiety/Panic, Depression (Dysthymia and MDD) and a vast array of other struggles, concerns and stresses.

My Approach

My team and I are passionate about what we do. We have a wholistic approach in the therapy we provide. Our approach is somatic in that it recognizes the relationship between mind and body.     We do not believe that we are an island but rather the sum of our experiences with others and within the community/culture we have been exposed and participate in.  In the past our clients have expressed appreciation for our genuine, knowledgeable and heartfelt support.

On a Personal Note

I confess I love Peterborough!  I grew up in Toronto and value the experiences that I have had in such an amazingly diverse city.  I have worked as a waitress, leather cutter, security guard, factory worker and multiple other positions.  I attended university part time at first. I guess I am saying that my education extends well beyond the walls of a university.  These experiences I feel help me in offering compassionate and empathetic support because “I get it!” I have walked a similar path as many of the people I support. The MACP candidates that are part of the team were selected to join Advocating Hope because they too have had lives that go beyond school-based learning.

So why Peterborough?  It started out that I moved to a town of 1300 to raise my children. I love the rural life even with it being fraught with its own unique obstacles.  I am a naturalist at heart and even pick fiddleheads in the spring.  In the summer months I kayak the lakes in the Kawartha Highlands, Algonquin and at Killbear Provincial Park.  I still camp in a tent (might have to rethink that I suspect). I also enjoy my mountain bike and walking Nipiish (our family dog from Attawapiskat).  In the winter I do my art (bead weaving) and swim at a local pool.  

I welcome you to contact me for a free confidential consultation session or visit my website for further information or to book an appointment/consultation time.  I look forward to chatting with you!
