Dr. Denier is great….She’s an extremely good cardiologist. I highly recommend her. Also, her staff is wonderful. They actually call you back with test results, and they return phone calls. How many doctors’ offices do that today?
Brenda R.As a former nurse, I am very selective about the physicians treating my family. Dr Hordes gained my respect by first walking into the room and extending his hand to shake with first my husband, the patient, and then myself. He gained my trust through his calm demeanor, pensive consideration of the issues, realistic treatment plan and attention to detail. I cannot recommend him highly enough and have the highest confidence in his ability.
Bunny E.Outstanding ! Couldn’t be happier Dr. Helak is thorough and on the spot! Great physician!
