Whenever I bring up certain concerns I have, after speaking with Dr. Christopoulos, I no longer feel concerned. She always explains things to me very clearly.

I didn't feel as though my concerns were given validity and she made it clear they weren't open for discussion. There was a lack of empathy. From a clinical standpoint, she was very thorough and very knowledgeable of current research.

As a new patient, it took a really long time to get an appt. However, it was well worth the wait. Dr Christopolous was incredible! I have never felt so seen and heard by a clinician. She took the time to understand what I was going through and discuss care options. I didn't feel rushed or judged or dismissed at all. It was refreshing and greatly appreciated. The entire staff was lovely. I have already mentioned to several colleagues if they're looking for a new PCP, I have a recommendation.

Dr Christopolous has been my Primary care doctor for many years. She is empathetic, thorough, and listens (a biggy).She Is aware that I am a 24/7 caregiver for a husband with dementia and is helping me to stay healthy physically as well as mentally. She is a rarity in this day and age where doctors don't take the time to follow up on something that may be serious. I love my doctor.
