What patients are saying.

  • "We drove from Florida to see Dr. Kiesz. We had been told by the doctors in Pensacola that nothing could be done and to keep her comfortable until she passes. She was on the verge of leg amputation and had an artery that was 99 percent blocked. They said the procedures she needed were impossible to do. I reached Dr. Kiesz before Christmas and he got us in immediately. He completed the procedures that supposedly were impossible. He is a wizard. We are eternally grateful. The staff was incredible. Dr. Kiesz also got us into wound care and a wonderful kidney specialist. Words can't put into perspective what Dr. Kiesz and his staff were able to do."

  • "My Grandma was not the easiest patient for any doctor and with her dementia she thought all doctors were bad. Dr. Kiesz knew the right way to speak to her so that she knew who was in charge in a professional way. Not only that, the whole staff is amazing and so caring."

  • “Dr. Kiesz is a God send. I have gone to several cardiologists in San Antonio, Texas and apparently because I physically looked as though I was not sick, [they] dismissed me by saying, "you know a lot when it comes to medicine and you want everyone to jump when you think something is not right." I was told not to take my blood pressure at home. I then went to see Dr. Kiesz at the advice of a priest and close friend. Dr. Kiesz found 75% blockage to heart. He saved my life.”

  • “Dr. Kiesz is the best Endovascular Cardiologist in the country, not just San Antonio. I moved away from San Antonio in 2012 but I return to see Dr. Kiesz because there is no one else I trust more than him. I have and will recommend him to other people.”

    — Virginia M.

  • “Thorough and deliberate cardiac care; Dr. and staff fully explain all testing prior to and during exams; results are discussed in detail; Dr. welcomes interaction; I had 2 prior cardiologists and Dr. Kiesz is by far the most personal in his approach; my highest recommendation.”

  • "I have seen Dr. Kiesz for years. I had a blockage in 2014 - I had no symptoms - 95% in a main artery. He is always informed when he enters the exam room. Takes time to answer my questions. I definitely would recommend him."

  • "I do not know the technical aspects of all of this, just the emotional appreciation for not having my chest split open for a bypass procedure. He then put me on a course of medications to prevent clots and reduce cholesterol and I went home. I have been back for examinations and "troubleshooting," but most problems are of my own creation. My last visit he looked at me and said: "your heart is now in good condition, young man!" Sweet words for anyone to hear. I must admit that I am religious and believe in God and Angels. When I prayed for help, He gave me Dr. Kiesz and his staff. As far as I am concerned, Dr. Kiesz performed a miracle with me and gave me a new lease on life. ...I trust Dr. Kiesz completely!"

  • "Dr. Kiesz is an exceptional doctor and we are grateful for his compassion, skill and perseverance in healing my husband's critical medical needs. His resolve to find answers provided the hope and encouragement so necessary to endure long term issues and numerous procedures. We credit Dr. Kiesz for the quality of life my husband currently enjoys. Truly words cannot express how blessed we feel to be under his care. We are equally fond of his caring and professional office team members and also the cath lab team."

  • "Dr. Kiesz is a life-saver. I had stent implants before because of chronic heart disease. Dr. Kiesz looked at my case, gave me an evaluation and performed the implant surgery. I am a retired Lt Col and professional trainer with many commitments. After months I returned to see Dr. Kiesz because of a feeling of pressure on my heart. Again, he actually called the hospital and got an appointment for me, The procedure was an outstanding success. I feel like a new man--almost like a 20 year old. He is second to none, personable, professional and caring. His staff is also exceptional--they always have a smile and go out of their way to assist. If you have any type of heart issue issue, there is no question about where you should go or who you should see...Dr. Stefan Kiesz."

  • "I have been to his location at Tuscany Stone for the last 8 years and have had 4 procedures done, all have been a success and have gone smoothly, I highly recommend him for anyone looking for a great cardiologist that can do his own work at the table."

    — Mario P.

  • "I was told I needed open heart surgery so after seeing Dr, Kiesz for a second opinion it was without a doubt the best decision I ever made. The staff is very professional and I was relieved all I needed were a few stents. this Dr. is a world class Doctor. I do recommend you see him for any heart issue."

  • My name is Matt Stankovich. Dr. Kiesz and ALL of his staff in the Tuscany Stone office in San Antonio (and his surgery center off of I10) are by far the most dedicated, experienced, knowledgeable, friendly, and understanding people before and after my procedure to check for artery blockage. If you're looking for an MD that knows his business with clean surroundings and professionalism, I highly recommend you visit Dr. Radoslaw Stefan Kiesz. I'll never go anywhere else for any heart issues. Thank you Dr. Kiesz!

  • "Dr. Kiesz and staff are great. Dr. Kiesz is very caring and thorough. I was referred to him by Dr. Roka after an abnormal EKG. Dr. Kiesz conducted a series of tests that ultimately led me to Dr. Otero, Thoracic Surgeon who performed a Triple Bypass. Dr. Kiesz has a great sense of humor, he is fond of telling me that he saved my ass twice. Now after my second stent after my Bypass (last Friday) he has saved my ass three times. His staff is also first rate."

  • "Dr. Kiesz is one of my favorite doctors! He has an excellent bedside manner and you can tell he's very passionate about his profession and his patients and even when they're slammed, like they were today, you don't feel like he's in a rush to get you out of there. You have his full divided attention and he explains everything in non-medical terms so you have a clear understanding of your health."
