"Dr. Dharma was the cardiologist on call for Mainland HCA Houston Hospital when I went in for chest pain. He has great bedside manner. He is knowledgeable and listened to my concerns. I was scared and vulnerable and he and his Assistant Jess, NP were excellent."

— Healthgrades/Sharecare

"One week post-op from cardiac electrophysiology mapping study and atrial ablation. 5 stars. Pre-registration (thank you Shirley!) to check-in, all staff was amazing, friendly, and professional. A big thank you to the cath lab team, pre-op nurse Stephanie, Dr. Chaplain, and of course Dr. Burkland."

— Birdeye

"He was lying in a pool of blood surrounded by filthy equipment. Under his stretcher was a pool of blood that was nearly dried. When staff came in for one reason or another, no one looked at him as though he was a human being..."
