“Dr. Mazzei was warm and friendly and a great listener who asked lots of questions to get to some possibilities for my daughters complex symptoms that so far an er doc and 2 other doctors have not yet figured out. She ordered further imaging and follow up and even offered television as she will be returning to school out of state. We will be switching to her for our primary doctor for our family. We have had difficulty finding g a new provider who is anywhere close to our 14 years with a husband -wife family practice duo With a great office staff. The staff at this rice was also kind and greeted us and helped us with questions when we caulked and when we checked in with the kiosk. Office was clean modern and bright, yet warm and inviting. Nurses and Np/PAs were also kind and professional and friendly and knowledgeable. ”

This was an initial visit to change primary care doctors to a loction closer to home. Dr. Messei was very attentive, examined my complete record in MyChart She understood my immediate needs and discussed a follow-up physical in a couple of months. She was genuinely interested in my particular health needs and upcoming surgeries. She was considerate and I look forwrd to being in her care..

This was my first time receiving care from Dr. PIFANO DIANA MAZZEI CAROLINA because my primary care physician was out this week. She was very courteous, professional, and caring. She was very thorough and listened to my concerns. She took great care of my needs.
Doctor is my New Primary Physician! Very Happy!
Have already recommended Dr Mazzei to a friend.
