Almost no waiting. Dr. Abbie was very helpful!!
Abbie is the best! Doesn't waste time, but gives time to answer all questions. She makes you feel comfortable enough to discuss anything.
Very organized and efficient.
My appointment was good, the PA explained everything to me in a way the everyday person could understand
It was great! I couldn’t find the building and was way late but let me keep the appointment anyway!
I was recommended to see Dr. Allison Venner for a colonoscopy by a trusted friend. After my colonoscopy she recommended I undergo an endoscopy as esophageal cancer took my brother's life. I agreed and Dr. Venner preformed the endoscopy. This was fortunate as the results showed I was likely heading down the same road as my brother, but caught at the precancer stage. I was referred to Dr. Nathan Kwak for an EGD treatment.
Dr Fenton and his colleagues are wonderful. They take the time to listen and work with me to get the issues resolved. Been coming to Dr. Fenton for around 15 to 20 years now.
The staff are all very friendly and helpful.
The PA took her time with me. She explained things in a way that I could understand and gave me some great feedback and options for my condition.
Brooke was very kind & explained things in a way I could understand.
The infusion nurses, Docs, P.As staff at Utah Gastro are the best. They are informed about my condition & specific reasons for my visits, caring & always have up to the minute info about treating my crohnes. I rarely wait even 5 min to see my nurse or doctor. They are the best!
Very friendly and informative. They care
Dr. Frech has been my gastroenterologist for years. He’s great!!! I see Abbie, as well. Saw her just last week. She was friendly, helpful, and reassured me that they’ll get to the bottom of my present situation. I have zero complaints. I also appreciate Dr. Fentons contribution in my present situation.
Dr. Fenton is a favorite, and so is Brooke & Paul. Very disappointed in the person who schedules appointments (very rude), and not considerate of someone who isn’t feeling well and needs to see the doctor.
Great customer service. Dr. Doxey was amazing. I felt safe, comfortable and had a great experience.
Dr Harmston is great, but for the past 2 years, I've been seeing Abbie Siebenhaar, since my Crohns is under control and I've not had any issues. I really only have to go in for RX refill every year and to have some bloodwork done.
Abby is not as "comforting" or compassionate as Dr Harmston, but since I am not having problems I don't need a PA with as good as a bedside manner as Dr Harmston.
She is professional and did tell me that since I had to change medications due to insurance not covering Humira any longer, to pay attention to any symptoms after switching to The generic (Amjevita) and to call her if I had any issues.

Such a smooth process! Scheduled on the phone, followed the instructions they emailed, and showed up for the procedure. No referral or extra visits needed for a standard screening colonoscopy. Friendly staff, excellent doctor, and I’ll be back in ten years.
The infusion nurses at The Old Mill location are the nicest I’ve ever had. I have grown a relationship with them over the years. They take such great care of me, the clinic is always clean & orderly, and Danielle does a fantastic job of inserting an IV without pain. The biggest thing I appreciate is that they are so helpful when coordinating with insurance, the drug company, and the assistant pay program. They are so knowledgeable and on top of it!
Everyone is nice, polite and professional.
The PA who helped me was a breath of fresh air! She was kind, empathetic, knowledgeable, and answered all my questions in detail. She was able to get me scheduled for the soonest endocopy they had. She also called me the evening of the appointment and asked if I'd thought of any other questions! Excellent customer service and a personal touch! I was so pleased with my appointment!
