Patient Reviews
Mar 28, 2024
Dr. Alexander is ALWAYS very attentive to my Cardiology needs and beyond. His Expertise, Knowledge and Practices are TOP NOTCH. Since my introduction to Dr. Alexander in 2017 (Prior to my Angioplasty) His vast knowledge of medicine enabled me to avoid Open Heart Surgery (which was the next level of medical procedures, which I would have undergone if the Scripts he gave me didn't work as well as they did) His management of my heart disease condition has been so successful, my life currently is void of any clear and present danger. His vigilant yet human approach to Patient Health Care and Healing, Is absolutely due to Dr. A's approach to literally saving Lives, and nurturing individuals to continue on a happy healthy path.Dr. A IS MY HERO!!!Always Respectful and Thankful,Anthony M ~
