"I was a few minutes late but did not get stuck in the waiting room forever, I was in a room waiting after going back for a while longer BUT they had a touch screen full of simple but helpful knowledge about your gastrointestinal insides so the wait was useful. Everyone was well mannered and I feel like I'll get results from going here before too long!"
"Dr Conkling has always been professional and also caring. I feel like he understands me and really understands my concerns.

"My primary care Dr. believed that I could be anemic, so she had me go to Dr. Conkling. I had gone through the normal upper & lower GI test, but didn't find the cause of my issue. So Dr. Conkling ordered wanted to make sure that the issue was not in my small intestines, which involves swallowing a small camera. For what ever reason the camera got stuck in my intestines about 3 hrs into an 8 hr test. That was very concerning to Dr. Conkling and he quickly ordered another batch of tests to make sure the camera wasn't stuck in my system (of which I was sure I had passed it). My primary care Dr. & Dr. Conkling finally thought that maybe the care malfunctioned and had me swallow another 1. Interestingly, it to got stuck after hour 3 of the 8 hour test. This to, did not reveal why I had anemia. To end this long story, what I appreciate about Dr. Conkling is that he is not willing to give up. He is still looking for ways to find out what is causing this anemia."
"This was my initial (consultation) with Dr. Blonsky. He was very thorough with his assessment and information, was not in a hurry to leave the exam room. I appreciated his patience and bedside manner. His nurse was very nice."

That was a very good move on our part and I thank God for Dr. Stanton moving to Tulsa!"

"Dr Blonsky and the Staff at AGA are by far the best of the best for addressing all of your Gastro needs. They are competent, confident, and compassionate. Being teamed up with Tulsa endoscopy you couldn’t be in better hands. I’ve had gastric problems for over 20 years and Dr Blonsky was my Dr for a short time and because of an insurance change I lost him as my specialist. I was not only devastated but received inadequate care elsewhere. Trust me because I have been through multiple procedures and have a very complex gastrointestinal history so I do know most all of the specialists in Tulsa and I can say with confidence all the best work at AGA. If you have experienced an issue in the past or in the future with them address it with them. Most times it’s just a miscommunication and I know they will do everything to rectify whatever the issue is."

It’s great to have a doctor as caring as doctor Volak in your corner. I highly recommend and his team."
"Dr. Volak carefully listened to my teen’s concerns and asked thorough questions to better understand the issue. He explained things to us rather well, even drawing some pictures to explain things. Medication was also not his immediate solution , which is deeply appreciated, especially when there are alternatives in this case that may actually address the root of the problem. I hope he trains medical students!"
"25 yrs ago I went to 3 different Gastro Dr’s who tried meds that never resolved my problem. After 1st trip to Dr. Volak, I’ve never had this embarrassing problem again.

I asked questions that he took the time to answer and explain his answers. I highly recommend Dr. Nightengale. He is an excellent gastroenterologist!"
"I highly recommend Kevin McNamara. He has performed two procedures for my family over the last two years, most recently a colonoscopy for myself.

He is a caring, professional and thorough doctor."
"Dr. McNamara was great. Very kind and informative. Explained everything prior and answered all of my questions.. So was everyone at Tulsa GI.

Dr. Volak clearly explained every step of the prep and the procedure, including what to expect, ensured that I understood, and answered questions I had with an interest in educating me. Dr. Volak used the most up to date technology, including a more than tolerable prep, to ensure he was able to get a clear and thorough view of my colon while decreasing the uncomfortableness patients typically experience. I need repeats every five years and Dr. Volak is my choice to handle all my future gastroenterology care."
"First the office staff was very congenial and efficient. Dr. Volak listened to everything I had to say, asked some questions and then he said some tests would have to be run to diagnose what could be going on. He said they would take very good care of me. I was referred to scheduling and they too were very good and thorough at explaining everything and setting up the appointment."
"Dr. Volak was very informative about the procedure. He made me feel very much at ease. As this is something I really don’t want to do but I know that I need too. The staff was very professional. Just an all around great visit."
