"Doctor Patel has been my “go to” AG essentially since he joined the AGI team. Our interactions have scanned the spectrum from procedures not necessary to those prescribed. He has always been candid, thorough, and understanding. Because of his care I no longer dread the procedures that define gastroenterology."

"Dr. Conkling has been my Gastroenterologist for many years now. He is the only Doctor I have that literally takes the time to visit with me about my medical history, my current physical health and future plans to help me through my good health journey. I truly know that he saved my life AND helped me have a better quality of life, by finding and treating my medical issues. I appreciate being heard and I appreciate how you discuss medical treatment and procedures with me, giving me the opportunity to choose from options that work best for me. You are straight forward and that is helpful. Dr. Conkling has no problem speaking directly with me over the phone, if there are questions or conversations best addressed by him. He puts me at ease and I trust that he has my best interest at heart. Thank you, Dr. Conkling, for treating me like a human being. Unfortunately it's hard to find this type of consistent caring medical environment these days. Dr. Conkling provides a safe place where you feel as if you are working as a team. I leave feeling confident that I'm in the right place. Keep doing what you do, Sir. You are one of the best for sure!!!! Many blessings. Sadiqa LaNear"
