Care Philosophy

My care philosophy is quite simple: the patient comes first. I want all of my patients to feel comfortable and informed with me. I understand that each patient’s diagnosis can feel different for them, so I don’t believe in blueprinting treatment plans. I strive to create personal treatment options that fit a person’s understanding, lifestyle and overall comfort level.
