Caring, knowledgeable and courteous. One of the best I have known! Well done and I would highly recommend.

07/03/2025

Again, see my first comments. What is also valuable to me is that she has office hours in the Chelsea Professional Building that is 4 minutes from my home. Probably the most important is the type of person she is! Well done! Great service and convenient location!

07/03/2025

I would only repeat what I said earlier. She is the consummate professional.

06/10/2025

Since she took over my care, she has changed several of my meds for the better. She seems to constantly report the latest findings in medicine (took me off statins and put me on Repatha, reduced my Losartan and increase my Hydralazine) and gave me scientific reasons for doing so. I would recommend her to anyone!

05/29/2025

Dr. Holtze was very supportive of the issue discussed and stepped in where I needed assistance. She also provided a tip which I most certainly will use in the future.

Difficult to get an appointment. Waited from August till May

04/17/2025

I have only been there once, but happy so far!

04/07/2025

Great seeing you, but it's only once a year! I had a hard time getting an appointment scheduled since your schedule is only available 2 months in advance, and even then there was nothing available-it took another 2 months to get on a list, then another 2 months waiting for a time, ANY time. I hope next year is better, because I really like you as my heart doctor!

03/31/2025

Dr. Holtze is very professional yet kind and knowledgeable. She was recommended to me by my former cardiologist who left the practice. He said “You will like her” and he was right! She spends time with you and listens to what you say.
