About Marissa K Costello

About the Provider

I chose to become a family medicine physician because I wanted to work with patients to improve their health throughout their whole lives.

My care approach is all about treating the whole person, rather than just your symptoms or specific medical conditions. I believe care encompasses the physical, mental, emotional, social, and spiritual aspects of a person’s well-being. By establishing long-term relationships, I’m better able to provide patient-centered care that best meets your needs and values.

I’m passionate about preventive medicine, and I always encourage patients to take an active role in their health. When I see patients making improvements and achieving their goals it truly brings me joy.

    I was interested in getting a vaccination for shingles but despite my insistence she explained the reasons to wait (I had just been through shingles and I need to wait at least 6 months before getting the vaccine for maximum effectiveness.) She had to say it a couple of times before I really understood, but she took the time to explain in different ways. I appreciated that very much.
