Dr. Marroquin is an excellent doctor and I trust him with my heart health care. He takes the time to explain things to me and my husband and truly cares about your treatment. Thank you Dr. Marroquin, we appreciate all you do.

Dr. Marroquin is excellent in listening to my concerns. I was on pain medication last fall for a back injury and was concerned about the pain medication's effects on the heart. Dr. Marroquin was thorough in explaining the medication, and he was very reassuring about any future concerns I might have about the medication or the heart, offering to call or email at any time.

This was my first appointment with Dr. Marroquin. He came to the appointment well prepared. It was obvious he had taken the time to become thoroughly familiar with my condition. He asked thoughtful questions and patiently listened while I attempted to explain the progression of my case.
