Co-founder, Advanced Injector & Medical Aesthetic Specialist

Deanne Pilsner, RN BSN

Deanne Pilsner graduated from the University of Lethbridge in 2011 with a Bachelor of Nursing. She began her career at Foothills Medical Centre in Calgary, specializing in high-risk obstetrics and operative nursing for nearly a decade. In 2017, she transitioned into head and neck surgery, working alongside Dr. Jon Dautremont as his practice manager. With a strong commitment to accessible, high-quality patient care and ongoing education, Deanne co-founded Basis alongside Dr. Dautremont, helping establish Basis ENT & Surgical, Basis Allergy & Immunotherapy, and Basis Medical Aesthetics.

After recognizing that many patients with allergic rhinitis were experiencing long wait times for care, Deanne and Dr. Dautremont became accredited through the American Academy of Otolaryngologic Allergy and opened Basis Allergy & Immunotherapy in 2017 to provide faster diagnosis and treatment. The clinic has since grown to include Canada’s only educational program for otolaryngologists seeking to incorporate allergy and immunotherapy into their practices. In 2022, Deanne assumed leadership of Basis Medical Aesthetics and now practices as the Lead and Advanced Injector, skincare expert, and consultant. She has completed advanced certifications for cosmetic and therapeutic treatments, along with training in dermal fillers and other facial treatment modalities, reflecting her commitment to thoughtful, preventative, and comprehensive patient care.
