Virtual and in person in Ottawa, ON Canada
I work with autistic people of all ages. I am a 2SLGBTQIA+ ally and passionate advocate for equitable health access. Clients typically see me for complex case management, assessments and system navigation. I work virtually and in person in Ottawa, Ontario, Canada.

About Me and How I Work
Armed with a Bachelor of Science in Nursing, my vision extends beyond traditional healthcare models. I hold a graduate certificate in animal-assisted wellness, reflecting my belief in the transformative power of human-animal connections in therapeutic settings. With a graduate degree in psychotherapy, I have deepened my expertise in mental health, approaching care through a nuanced and holistic lens. As I work toward a Master of Nursing Science to become a Nurse Practitioner, I remain dedicated to evolving alongside the ever-changing healthcare landscape.
Qualifications and Professional Experience
I hold Psychiatric and Mental Health Nursing and Pediatric Nursing certifications from the Canadian Nurses Association. My expertise is further shaped by specialized training in autism and direct experience supporting autistic individuals, which drives my advocacy for bridging gaps in a siloed medical system.
