Dr. Marroquin and staff are the best!!!!!

BAD: (1) Being charged a hospital visit fee just for the privilege of walking down the hospital hallways to get to the doctors office. (2) Lack of data record keeping in order to prove to insurance company that I am eligible for a new medication that may help preserve or extend my life. GOOD: Oscar Marroquin is one of the best, most caring physicians I have had the privilege of knowing. He is a very knowledgeable and caring individual.

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.
