5/5

I met with Dr. Marisa Fander Feen for the first time this morning. She and the staff were very warm and welcoming. They spent a great amount of time learning about my medical history, and how to move forward with any questions I had. Giving her a try, as I'm definitely changing with age, feels like a positive decision at this time. Thank you.
