Dr. Patel is a professional and compassionate physician. I highly recommend him.I sought out Dr. Patel for his expertise in kidney stones. After several studies, it revealed my right kidney was very enlarged, scarred with multiple stones of various sizes and functioning at a low percentage. Dr. Patel explained the seriousness of my condition and thoroughly evaluated my options. We formulated a plan for best long term results. Dr. Patel successfully removed my kidney laparoscopically. As well as being an exceptional surgeon, he had great bedside manners. After surgery, Dr. Patel was very proactive in connecting me with the best nephrology team to ensure my other kidney remains healthy.Thank you for what you do, Dr. Patel.

Fantastic service. Dr. Patel was wonderful. He was caring and gentle and was a pleasure to work with under the most difficult circumstance (kidney stones)- he always made eye contact with me and held my hand (almost literally) throughout the process- The staff were equally caring. You seem to train your employees very well......because in reality is...... No one cares what you know, until they know that you care!!! You guys did and I am grateful!!!!
