Patient Reviews

Patient

★★★★★

I am incredibly grateful for the care I have received from Dr. Gim, who has been nothing short of exceptional throughout my treatment. He successfully implanted two stents for me and later identified a blood clot in my heart through his careful and thorough echocardiogram testing. His medical expertise is outstanding, and I truly credit him for helping protect and improve my long-term health. Beyond his clinical skill, what sets Dr. Gim apart is his tremendous compassion and genuine personality. He takes time to explain every step, listens carefully to concerns, and makes you feel like a real partner in your care. I always felt respected, supported, and confident in his decisions. If you are looking for a cardiologist who combines deep medical knowledge with humanity, empathy, and professionalism, I cannot recommend Dr. Gim highly enough. He has made an extraordinary difference in my life.

Whenever I go into the office, I always feel like they "see" me, and the conversations I have with Dr. Gim, are always enlightening and helpful. Cardiac health is very important and they definitely are on top of my history. You will love this office!

My husband, Mike, had a mitral valve tear. Dr Gim was very thorough and provided an accurate diagnosis. He recommended a good surgeon. The surgeon repaired the mitral valve and Mike is doing great. We would recommend Dr. Gim wholeheartedly. He cares!
