Patient Testimonials

I had a 7mm kidney stone stuck in my ureter and as you can imagine was in a bad way. Dr. Patel used some minimally invasive technology to destroy the stone and evaluate my condition. He was hyper competent, answered all my questions and a great communicator. I feel very fortunate I found an expert of his caliber to address what for me was a really painful, serious medical problem.

Dr. Landman is a very caring physician and an exceptional man. He is very professional and treats his patients with great care. He has wonderful bedside manner and took the time to answer all of my questions about my condition and treatment plans available.

I feel very confident with Dr. Clayman. I would highly recommend him. I really appreciated the time he spent with me explaining my options and getting me back to daily life and teaching me about preventing kidney stones down the road. Thank you, Dr. Clayman!

Dr. Yaacoub is one of the most compassionate doctors I have ever met. He goes above and beyond with his care. He helped advise me on how to manage my kidney stones with my diet, which I truly appreciated. Although it is outside of his area of specialty, he has urged and helped me to quit smoking cigarettes to help my overall health. Thank you for all you do, Dr. Yaacoub!
