I am an orthopedic surgeon specialized in upper limbs at Pierre Boucher Hospital in Longueuil since 2018. Along with my extensive post-secondary education, I have had a military career in the Canadian Armed Forces for over a decade. Now retired from this profession, I remain aware of how physically demanding this type of career can be.

I care about the positive evolution of my patients and favour a multidisciplinary approach, as I work closely with a team of doctors with a musculoskeletal specialization, physiotherapists, occupational therapists and hand therapists.

During an initial consultation with me, we will go over your musculoskeletal history, review the x-ray, neurological and/or medical examinations pertaining to your request for consultation and once we have gathered the necessary information, we will work together to find an immediate and long-term solution whether it be surgery, injections, orthotics or referral to the appropriate therapist.
