Dr Margaret Fischer and her staff are wonderful ! I had a pacemaker implant on 10/21 and they did a great job from start to finish. They were professional, skilled, and compassionate. Dr Fischer and her team explained everything in detail and had me relaxed and at ease. By far the best doctor in the area. I am grateful and highly recommend Dr Margaret and staff. Thank you for caring ! Susan Mose
Love her! I have been seeing her for only a few months, but I'm so impressed with her she is very knowledgeable and organized about her job. She took a personal interest in me, like I was her only patient.
My first visit with Dr Fischer. She is friendly, professional and engaging. Answered all of our questions thoughtfully and in detail. Would definitely recommend.
Dr Margaret Fischer. Simply the Best. I can't begin to describe the skill and professionalism I received from her and her team. I was in her care, for AFib, from February 2025 and released from her care October 2025. Complete Success Thank you so much Dr Margaret Fischer!
Dr Fischer was able to get me back to where I needed to be. For 2 years my heart rate was close to 2x the normal rate She is excellent and so is her staff
