First met Dr Krock in the cath lab in Frisco to receive a stent after a cardiac arrest. Skill is impeccable and I quickly signed on to have him as my cardiologist. Helped through treatment, recovery from quad bypass surgery. He's helping me with a maintenance regimen going forward. Does a great job of communicating and explaining why we're doing things. Got me back to normal life in short order. I have and do trust him with my life and would recommend to anyone!

At my 1st appt. I was asked to reschedule due an emergency. The 2nd appt. I waited 2 hours to see him. He was rushed and did not explain anything. He diagnosed AFib and prescribed a blood thinner. I made another appt. and spent a long time with his PA and less that 5 with him, he did not like me asking questions. I went to an EP cardiologist and was told I did not have AFib at all and did NOT need a blood thinner. He might be good at surgery but as a clinician, I was very disappointed.

I don't doubt Dr. Krock's skill or knowledge. I suspect in his many years as a doctor, he's had to deal with a wide variety of patients with different levels of intelligence. My family physician understands that I am educated, do my research, make my own decisions. He understands that he is my advisor, not my boss. Dr. Krock barely listens to what I have to say, and it has come close to costing me. My biggest problem with him is he thinks he's the only one who has input in the visit.

I HAVE BEEN SEEING MARC KROCK FOR MANY MANY YEARS. AFTER RETIRING FROM THE MEDICAL BOARD AS SENIOR INVESTIGATOR AND KNOWING ALL THE PHYSICIANS , I KNEW THAT I AM IN GOOD HANDS WITH MARC. SO IFF YOU NEED A CARDIOLOGIST HE IS THE ONE TO GO SEE, TRUST ME YOU WILL BE SO GLAD YOU DID.

Dr Krock has been my cardioligist for 15 years. I always arrive early for appointments and usually get called in within a few minutes to start the process. His office and the waiting room are always sparkling clean, and the receptionist and other personnel are friendly and efficient. I attended my appointment today and waited less than 3 minutes before being called in. DR Krock is friendly and efficient, and answers my questions. He spends the appropriate time with me.

Outstanding cardiologist with very thorough approach and an amazing listener. He clearly understood my symptoms and diagnosed me and treated me in the first 2 visits. I did not have to see him again until 6 months and I had no recurrence of symptoms in the time frame. Outstanding care.

He takes the time to listen to my concerns. I never feel "rushed". Every time I see him, he knows about me! Often he returns calls personally. And, his office staff is always courteous.

I am a long term CHF patient. I contracted AF and was told just a progression of CHF. Totally wrong. It was due to a drug I told him I was on. My research showed the drug could cause AF once i stopped the drug the AF went away. Mean time i was put on blood thinners now i am off! I feel he does nothing to diagnosis real issue just assumes based on current condition and follows ACC guidelines. If I had not done my own research i would have AF and on blood thinners
