Patient Care Philosophy

I believe in compassionate patient care, taking into account each patient’s individual needs and giving them a central role in their care. The best outcome is often achieved when patients and physicians work together towards a common goal that is specific to each patient’s needs and treatment goals. As a physician, I believe in not only providing patients with my professional guidance but also empowering patients with the information they need to then make the best decisions for themselves.

Dr. Vachon was fabulous in my time with her. She was compassionate and knowledgeable. It was maybe the best first session I’ve had with a doctor, and I’m 68!

Great doctor. If she wants testing done, she gets it done and gets you back to a normal life.
