- 5.0Aug 29, 2025Dr Mandel provided outstanding care as he filled in for Dr. Frielich. He explained a complicated medical issue very clearly for the lay person and responded to all of my questions and concerns similarly. Dr. Mandel's interpersonal skills immediately put my wife and I at ease. Subsequent interactions with Dr. Mandel demonstrated the same high level of professionalism and ability to connect with the patient/me during a challenging medical time. Outstanding!

- 5.0Aug 28, 2025Dr. Mandel took time to listen to all of my questions. Last January I had an appt to ask him if I was on the right statin. He looked at my scan (ordered by my primary care doctor) and said we need to talk. He tried to keep me calm but had to tell me I had an aneurysm and needed to see a thoracic surgeon. He told me the surgeon may look at the scan and have a different opinion but he wanted me to follow up immediately. It was the way he delivered the information that even though I was scared, I knew I had to call. It ended up I had a bicuspid aortic valve from birth and a large aneurism. If I didn't trust my doctor and receive the information in the way it was presented I may not have been able to write this comment. He is one of the doctors I credit with saving my life. It's important to be able to ask a doctor questions, be heard, and given answers that are easily understood. I'm very thankful for him.
- 5.0Aug 26, 2025Dr. Mandel is professional, personable and attentive. He addressed all my concerns and/or questions in an understanding manner. He discussed the importance of proper nutrition and exercise and encouraged me to "keep up the good work". My husband and I are both patients of Dr. Mandel and have referred other people to him as well. The receptionists and medical assistant were friendly and helpful.
- 5.0Aug 21, 2025Dr Mandel and his entire staff are great.
