I specialize in the assessment and treatment of obsessive-compulsive disorder (OCD) and anxiety disorders, including generalized anxiety disorder (GAD), panic disorder, agoraphobia, emetophobia, and social anxiety disorder.

I work with individual adults (18+) only. I do not work with children, teens, couples, or families. I’m also not a good fit for people looking for help with psychosis, chronic pain, substance use, or disordered eating.

I am only seeing clients for telehealth sessions via online video. If you’re unsure if online therapy is a good fit for you, please contact me and I’ll be happy to discuss any concerns!

Individual therapy sessions are 50 minutes in length. If you are wondering whether you have a disorder, such as OCD or an anxiety disorder, general assessment appointments are usually scheduled as two 90-min sessions. At times, we may decide it’s best to schedule shorter or longer sessions. We can discuss this during our work together when necessary.

I provide individual, evidence-based treatment for adults virtually via Doxy.me, which is a secure and PIPEDA- and PHIPA-compliant telehealth platform. Upon booking, you will be provided a link to be used for your telehealth appointments; simply type this link into your web browser at the appointment start time.

I am currently only able to offer appointments from 12-2pm and 4-6pm MST (2-4pm and 6-8pm EST) Mon-Thurs. If my hours don’t work for you, please reach out and I can recommend someone who may be helpful.

The number of treatment sessions you will need will vary depending on the severity of your symptoms. Generally, if you have OCD, you can expect 18-25 sessions (about 6 months). If you have an anxiety-related disorder, you can expect about 12-15 sessions for panic, agoraphobia, or emetophobia. For GAD treatment, you can expect between 20-25 sessions. Typically, PTSD can be treated in 12 sessions (about 3 months).

Sessions with me cost $250.00 per 50 minute hour.

No, I do not direct bill to insurance. I do provide the option of paying with credit card so that people don't have to pay out of pocket while they wait on their insurance company to reimburse them! Detailed receipts will be provided for insurance reimbursement.

Unfortunately, I am unable to offer sliding scale fees at the moment so all new clients coming in will be charged my full rate, which is $250.00 per session. I’m happy to provide some names of others who offer low cost services or a sliding scale rate, keeping in mind that these individuals tend to be students, unlicensed professionals, or licensed professionals who don't have expertise in OCD or anxiety disorders.

All major credit cards, including AMEX, and e-transfer payments are accepted.

A minimum of 24-hours notice is required to reschedule or cancel your appointment. The full session fee will be charged for late cancellations or no-shows. Exceptions will be made if there is an emergency.

The difference is mainly in education, training received, and scope of practice.

Psychologists hold a doctoral degree (Ph.D. or Psy.D.) and/or a master’s degree (M.A., M.Sc., or M.C.), have extensive training in research and/or psychological practice, and are able to assess, diagnose, and treat psychological disorders. They cannot prescribe medication. There are many types of psychologists that will differ in their approach and professional activities depending on their branch of psychology. For instance, a clinical psychologist is interested in whether a client has a serious mental illness as this will directly inform the treatment they provide. Psychologists who practice from a clinical framework gather information, provide a diagnosis (including doing differential diagnosis and identifying rule out conditions), and do evidence-based treatment for serious mental health disorders. By comparison, a counselling psychologist is more client-centered in their approach and views common factors in therapy (e.g., therapeutic relationship, client motivation, client expectations of therapy, and client strengths and skills) to be the main drivers of client change. They tend to focus on helping clients cope with life/work-related stressors and mental health concerns. They may or may not choose to diagnose or treat severe mental disorders.

Psychiatrists are medical doctors who went to medical school and completed further training in residency. They are able to prescribe medication. Psychiatrists specialize in the diagnosis and treatment of severe mental health disorders. Both clinical psychologists and psychiatrists tend to work with clients with severe mental illness.

Counsellors (such as a CCC) typically provide guidance or support for “developmental issues, addressing and resolving specific problems, making decisions, coping with crisis, developing personal insights and knowledge, working through feelings of inner conflict or improving relationships with others” (CPA, 2025). Counsellors do not tend to work with those experiencing severe mental illness.
