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 thought she was very nice. She asked all the right questions some I would have never thought to ask. She made sure to explain everything to me as well as give me different options for treatment. I liked her a lot and will continue using her as my primary care physician as long as I can!

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.

Marissa Costello is a great listener, great doctor, great woman, a great individual, she was kind, professional, respectful, ready to help and privacy was big for me. She helped me to achieve the medical care and treatment and accommodations that I needed and or referred me to other specialist who could help me with the things out of her profession.
