Patient Reviews

Patient

★★★★★

He is a little arrogant BUT when you know your profession like he does, that's ok. He placed a pacemaker in me with ease. His staff have always been very polite and professional. Whenever I have had an issue they have always gotten me in for brief visits. Tech Donna is also very knowledgeable and very understanding of what a patient feels. To date this has been the best cardiologist I have met.

I think the other three reviews are made up. I saw reviews and made a appt with him. Today met him .What a cold heartless indvidual. He acted like he didnt want to be there and just was so rude to me. My old cardiologist who put my pacemaker in moved out of state. LOOKING FOR A GOOD ONE IS HARD BUT STAY AWAY FROM THIS GUY!!!!

Patient

★★★★★

Inserted a new more modern pacemaker in my husband. Great results: more energy, clearer mind, feels better. Dr. Has good bedside manners & great reputation with those working with him.

★★

No issues with the doctor. Horrible staff support at both locations. They are capable of cancelling your appointment without notice and then have you wait after check in without telling you about the cancellation! Simply incredible.
