*Dr. Desai & his entire staff are really excellent! The procedure I had was a complete success!
He has a great reputation and several seniors in my community have gone to him for heart issues and been very happy. He is the only doc that called my friend after the friend's wife died to express sympathy as he was her doctor.
*Dr. Aseem Desai is an excellent cardiologist!
*Dr. Desai is thorough, genuine, clear and his sincerity is always evident.
Dr. Desai is the best. I have had 3 Cardiac Electrophysiologics. He is so good. This is why my health is better. He recommended the Medtronic heart link instillation in me inn 2015 which isolated one of my bad heart areas that had not been previously detected while under the care of other DR's. He cares.
