Sexual Health Institute

Built by clinicians
who do this work.

Tami-Lee Duncan and Cassandra Kleefman are registered psychologists with specialized practices in sexual health. The Sexual Health Institute exists because both of them kept having the same conversation with colleagues: there is no training program that does this properly. So they built one.

I have been a registered psychologist since 2012, and sexual health has been the core of my practice for most of that time. It started by accident. Early in my career, my supervisors thought it would be amusing to send clients with sexual dysfunction my way. It turns out I do not rattle easily, and I discovered a genuine skill for making uncomfortable topics feel safe. I have been working in this area ever since.

My practice spans sexual dysfunction, pelvic pain, trauma, and couples therapy, with locations in Victoria, BC and Edmonton, AB. Alongside clinical work, I have spent nearly a decade as an annual guest lecturer at the University of Alberta Faculty of Medicine, teaching medical students how to take a sexual history and assess and treat sexual dysfunction. I am also an Adjunct Professor in the Department of Educational Psychology at the University of Alberta, where I have trained and consulted the next generation of counsellors since 2017.

I developed managingsexualpain.com, a five-module online workshop for clients navigating pelvic and vulvar pain, which reflects the same instinct that drives this training program: if the resources do not exist, build them. The Sexual Health Institute is the clinical training version of that same conviction.

Registered Psychologist · M.C., Counselling · Edmonton, AB

I am a registered psychologist with a specialty in sexual health, pelvic floor pain, and couples therapy. What drew me to this area was not a single moment but a pattern: I kept noticing how many people were arriving in clinical settings having already spent years being under-served, misdiagnosed, or told that what they were experiencing was not a real clinical concern.

My training spans intensive sex therapy, pelvic health, EMDR, Gottman couples therapy, and emotionally focused therapy. I completed intensive sex therapy training at the University of Guelph and a sexual health certificate at the University of Alberta, and I have trained extensively in the intersection of psychological and physiological contributors to sexual pain. I am currently an Associate Professor at City University of Seattle and a Sessional Instructor at Concordia University of Edmonton.

Alongside my clinical work, I speak publicly on sexual health at professional conferences and in the community. I presented at the Sexual Health Alliance Annual Conference in 2025 and the ASPSH Biannual Conference in 2024, and I am a regular invited speaker at MacEwan University. Education and clinical work are not separate for me. The Sexual Health Institute is an extension of both.

What we believe

The training gap is real.
So is the cost of it.

Graduate programs in psychology, social work, and counselling devote fewer than three hours to human sexuality on average. Clinicians leave their training without the language, the diagnostic knowledge, or the clinical framework to meet one of the most common concerns people bring to therapy.

What follows is predictable: clients are not asked. Referrals go nowhere. People spend years being told their concerns are normal, psychological, or not worth investigating, by clinicians who simply were not trained to investigate them. This is not a failure of individual clinicians. It is a structural gap in how training programs are built.

This program is our answer to that. Built from years of combined specialized practice, medical education, and a shared conviction that clinicians who want to do this work deserve training that actually prepares them for it.

Evidence-based, critically taught
We teach the research, including its limitations. Foundational models are taught in historical context, not as the current standard.
Clinically honest
We tell you what we actually think. Feedback wrapped in softening is not useful. The same directness we bring to clinical work, we bring to teaching.
GSER-inclusive by design
Gender, sexuality, eroticism, and relational diversity are integrated throughout the curriculum, not siloed into a single module. Affirmative practice is a foundation, not a supplement.
Built for the next day
Every module is designed around clinical encounters that actually happen. You should be able to use what you learn in session the following week, with your current caseload.
Consultation, not performance
The cohort component of this program is built around real cases, honest difficulty, and collective problem-solving, not polished case presentations designed to look competent.

Recognition and media

The work speaks.
Occasionally, so does the press.

Train with people who
do this every day.

Every module in this program is built from direct clinical experience, not synthesized from textbooks or assembled from a distance. When you train with us, you are learning from clinicians who are still in the room with these presentations, every week.
