Reviews for Adult Gastroenterology Associates
"I was notified by email that I needed to schedule my colonoscopy. I called for an appointment with Dr. Stanton and received all the information I needed when we met. My colonoscopy is scheduled later this month. As always, I felt well informed and totally at ease."
"My visit to OSH was fantastic outside of the fact that I was there for a colonoscopy. That drink is disgusting and made me really nauseous. But all of the staff were amazing and really sweet. The only person who didn't even say hello or anything was one of the people in the or. He had lots of tattoos and facial piercings. I really wanted to see them too! But he wouldn't even look my way. It was kind of disappointing. But I know everyone has a bad day every now and then. So I don't think he deserves to get in trouble. He was never rude or anything. Just maybe a suggestion to smile and be friendly."
"This is Joyce McCoy I have been a patient of Dr Nightingale for over 18 years.. he is the BEST ! I have PBC and he takes care of me 100% I do all my endoscopy and colonoscopy there at his office on Kelly Dr. In Tulsa"
"Dr. Ryan was amazing and Took the time to answer all my questions. And he explained everything. Was definitely worth the 4 hour drive."

Highly Highly recommend this practice! It can be nerve racking getting procedures done, they all were so friendly, caring, they checked on my several times, they are literally the Best! They even texted afterwards to make sure I was doing good not having any issues! They run a tight ship! Thank you so much for making my first colonoscopy an amazing experience. I am recommending EVERYONE to your office. What an amazing team you have, from checking in to being wheeled out! So friendly and kind I cannot say enough, highly impressed! Thank you so much ❤️"
"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.

"Everything went very well. No issues whatsoever. Friendly efficient staff. I was in and gone before I knew it. It was perfect."
"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."

"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."

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. Also have sent 5 friends with similar problems & all just love him for his thoughtfulness plus within a wk. no problem. He’s an exceptional Dr."

"From the minute I walked in the office, I was welcomed by receptionist, very friendly and professional which put me at ease immediately. Everything was right on time and at one point I had at least 4 nurses check on me, each introduced themselves while being prepped for my colonoscopy. The Anesthesiologist came in and explained every step and then Dr. Stanton personally came in and walked me through every step and asked for any questions I may have. Just may be the best medical experience one could ask for considering why I was there! Everyone, including Dr. Stanton, were right there when I woke up and explained how the procedure went and what to expect the rest of the day. Honestly, I would recommend Dr. Stanton and entire Staff to anyone I know and encourage everyone at a certain age to get your colonoscopy here with NO WORRIES!! My Thanks to everyone in the office!!

When it was my turn and by the way it was on time I was taken back and they did the procedures and then off I went to recover. Everyone that I came in contact with was so nice and pleasant. For a procedure no one looks forward to it was no problem and Dr Nightengale came in before I left to let me know what he had done and that he had told my husband already. I was completely satisfied with my experience with him. Thank you Dr Nightengale"

He is a caring, professional and thorough doctor."
"Dr. McNamara and his staff made me feel comfortable with the process of a routine colonoscopy. They went above and beyond when I was nervous and had lots of questions. While no one can say they are looking forward to this procedure, I’d say this team at least makes it as easy and comfortable as possible."

Arrived on-time at 10:15am and the office processed the paperwork quickly. Both Dr Patel and the nurse anesthetist visited with me beforehand, kindly responding to my questions by 10:45am. Procedure was over in 45 minutes and I was alert enough to get dressed and my wife picked me up at 11:45am. Before I left, the report was on the patient portal and biopsy report was available the following afternoon. Once again, an exceptional experience!"

Would definitely recommend him to others!"
"For 10+ years I've suffered with and no one could ever figure exactly what was going on. They could always find several things wrong... but no luck on connecting the dots! I've had multiple Dr's run countless tests to try and treat my symptoms, even went as far as exploratory surgery... with no help. I was referred to Dr Clark by one of my wonderful doctors after he did some research to try and find me some help. I went and seen Dr Clark one week, he ordered a bunch of tests after setting with me and going over a ton of information. Then when he called me back, he had a diagnosis! Dr Clark takes his time and listens! He is very thorough to make sure you are taken care of! I have referred him to several people already and will continue to do so! If you are in need of an amazing specialist with a wonderful staff, I HIGHLY recommend you go see him. Sincerely, Rachel Goodman"

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 Blankenship is a great Doctor but the staff is lacking . The receptionist and nursing staff never returned my calls nor did they ever tell me the results of my colonoscopy. I have called and called but no one will call me back. I scheduled an appointment but never got a confirmation nor a reminder so I missed my appointment. I cannot get any communication at all."
"He listens well to my concerns and makes sure I understand what is going on with my body and what steps need to be taken to improve my body."
"Dr. Blonsky is very professional and caring in his field. He takes time in the office with his patients. The only reason I didn't give 5 stars was because it is very difficult to get the nursing staff to call you back, at least in my case. But as for Dr. Blonsky himself he is a 5 star doctor."
"All I really can say is when I went there I was very nervous and scared I am an ovarian cancer survivor I have almost 2 years. And when you’re getting scoped from top to bottom you’re nervous. But when I got there the staff was so nice they made you feel right at home they have a nurse that check you and I don’t know her name but she is amazing she’s a little older lady that she feels like grandma. And when the doctor came in he was amazing told you everything that he was going to do and made you feel comfortable I asked him I was nervous going to sleep am I gonna wake up and he said yes he’s an angel you can put your life in his hands I did and I’m smiling:)"
"From the moment I walked in, I was treated Like I was family. The Receptionist, the Nurse, and Dr. Blankenship was exceptionally well Concerned about the pain I was in. And Decided from from my CT.

"Dr. Volack is an amazing Gastroenterology Specialist, probably the best in Tulsa, as a retired RN, I've worked with and seen several, personally and professionally. He is engaging, never rushes through details of findings and takes the time to explain things in layman's terms. I will forever be indebted to him for finding my cancerous 24mm polyp September 4th, 2018. He has been a part of my treatment plan since that time, though I chose not to have Chemotherapy, BUT instead, chose Naturopath and he respected my decision. I am cancer free today, having had a Colonoscopy yesterday, and for the first time since I started having Colonoscopies, there were NO polyps. If you're looking for an amazing Gastroenterology Specialist, look no further than this gifted Physician."

"I saw Dr. Kevin McNamara six years ago and thought he was a thoughtful, kind, and thorough physician. When I needed to return to for routine care from the practice in April 2021 I was pleased to be able to request Dr. McNamara's services again. If this sort of thing (like having cameras in your nooks and crannies, or the diseases of digestive health in general) makes you nervous, his pleasant demeanor makes the unpleasant parts of GI healthcare just a little less unpleasant. When, according to doctor's orders, I have to return in five years, I hope to see Dr. McNamara again!"

"NO ONE wants to go through the prep for a colonoscopy, but if you have to, Dr. Blankenship and his staff at Tulsa Endoscopy Center is the one to see. The nurses and front office staff are the loveliest group of women I have ever come into contact with in a medical facility, and they make an otherwise uncomfortable situation so pleasant; Dusty, the Anesthesiologist is so comforting and nice, and Dr. Blankenship is the best! Thank you thank you to them for treating me with kid-glove hands!"

The whole procedure from originating consultation through completion (in my case, biopsy of a polyp) were done with confidence, discretion, and compassion. I'll be seeking Dr. Volak's services five years from now."

"I have been a patient of Dr. Conkling going on 5 years. I first met him in the ER. He kept me from bleeding to death. I then saw him on my follow up visit. I was diagnosed with End Stage Liver Disease. He referred me to a transplant center. The whole time I was still Dr. Conklings patient. He Was not only my doctor but was my advocate. I could ask him anything and he would always take the time to answer my questions. His staff is also professional and helpful. I would recommend Dr. Conkling to my friends and family."
"I was referred to Dr. Conkling by my primary physician. I appreciate the time he took to thoroughly discuss what had been going on with me health-wise these last 2 months and his thoughts on the matter. This is not something you get very often in the medical community. The endoscopy and colonoscopy he did for me went without a hitch and was professional, efficient and as much as it could be, stress-free.

"Dr. Kliewer is an excellent doctor who has performed a Colonoscopy on me twice to remove polyps and insure my health. The office staff is great to work with and everything is done efficiently and well. At the end of each procedure, Dr. Kliewer sat with me for a consultation to show me pictures and review his findings and prognosis.
