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"

"Dr Patel is totally awesome and very personable. He's very polite and gives you ask the information you need on your colonoscopy. I highly recommend Dr Patel."
"Best GI doctor ever!! I’ve been Dr. Volak’s patient for 22 years. Office staff is difficult to deal with on the phone—enough to wonder about the office efficiency.

I’ll deal with all of these issues in order to continue excellent care from Dr. Vollak."

NIGHTINGALE $97 and another bill for $300. Today I got a bill stating that I owe $897.76 I don't know what that is about but I want be going back."
"The Physician was very knowledgeable and attentive to my concerns. He focused on what I was saying and not on typing onto his computer, it’s refreshing to have a conversation with the physician and them to respond appropriately versus taking through the screen with uniform basic questions. I have already told family of this practice and advised them to check them out."
"Very impressed with all the staff. Very friendly and efficient. They made the experience very comfortable. The follow up has been good and information about what to expect very clear."
