It's 2025 and it seems this crazy world is getting busier and less personal when it comes to seeing physicians. I know I'VE experienced it. But seeing Dr. Princewill has been a breath of fresh air - and her professionalism, expertise and her kindness are just a part of who she is. Dr. Princewill listens to you without any rush and she fills you in on what's going on with you medically as if she's talking to a friend. I'm so lucky to have her as my cardiologist and couldn't be happier under her care. The MedStar team is also top notch!!!

I cannot speak more highly of my experience with Dr. Princewill and her staff. The communication prior to my visit allowed me to express my questions before my visit and register so effortlessly on the day of my visit. My visit began on time and each person I encountered was pleasant and professional. Dr. Princewill herself is such a great patient communicator. She gives you the sense that she has all the time needed to listen to your concerns and address your questions. By her caring demeanor you can tell that your health is important to her.
