I am beyond thankful for Dr. Sager. Trusting someone with your heart is not easy, but from our first interaction, I knew I was in the best hands. His treatment plan was clear and reassuring, and the pacemaker procedure went perfectly—I am still amazed at how smoothly everything went. I had read many reviews about him prior to my surgery, and they gave me the confidence to move forward with complete trust. Dr. Sager lived up to every word and more. I truly thank God for such amazing doctors who exist, and I’m deeply grateful for Dr. Sager’s care, skill, and dedication.
Great doctor. Takes his time and answers all my questions.
