About Patrick Costello, PA-C

Philosophy of Care

My practice style is always focused on each patient. My goal is to treat patients as I would like to be treated. This includes listening to each patient, giving thoughtful responses, and being considerate of their concerns. My goal is to be open and inviting so that patients can return back to the quality of life they deserve. You will mainly see me assisting in your surgery, and providing you post-operative care.
