The staff were kind and efficient. My video appointment with Dr. Tharalson was very thorough. He explained every step of the process which left very few questions on my end.
Terrific, everything was explained and I was treated like a person not a number. Everyone was kind and patient.
I have been seeing Dr. Tharalson for almost 25 years. In my humble opinion, Dr. Tharalson is one of the best gastroenterologists in the Phoenix area.
I like the level of care provided by Dr.. Tharalson. He performed my EGD. He is knowledgeable and professional. He worked to get me a huge discount on my medication which was about $1000 because my insurance will not cover that medication.
I have been a patient of Dr. Tharalson for 5 years and he has improved my quality of life! His staff at Phoenix Endoscopy are top notch! They are kind, caring, patient and pay attention to detail with the services they provide.

Dr. Tharalson is amazing.....
My colonoscopy was scheduled for 9:15 am April 17th. Everyone was very friendly and accommodating for my procedure.
Dr. Eugene F. Tharalson, M.D. took the time to explain to me about the procedure he was going to perform. When I woke Dr.Tharalson was right there to explain to me how the procedure went and how my recovery would be. I was treated with the utmost respect by everyone involved, from the receptionist all the way to the RN who escorted me to my ride home. I was so impressed by the care I received, all involved were so kind and reassuring. This was my first time ever having to be sedated for a medical procedure and everyone involved made me feel welcomed. I knew I was in good hands with everyone there, so all in all my procedure went great due to the kindness and professionalism I received by everyone. I would recommend Dr. Tharalson to anyone needing a colonoscopy or any other medical service he performs. Thank you to Dr. Tharalson and his team for all the care and support I received.

My wife and I are always more comfortable with Doctors like Dr Tharalson who is very analytical and careful in his diagnosis and treatment. He is very personable and puts you at ease which helps in describing your symptoms.
My previous Doctor retired and I was extremely pleased with Dr. Tharalson taking over. He takes time to talk with you before and after the procedure. His bed side manner is great! Very positive experience with Dr. Tharalson.
Dr. Tharlson is a very compassionate caring dr who put patients at ease with his humor and knowledge. I was uneasy the first time I saw him and within the first few minutes I knew I had found the right dr.
Visited Dr Tharalson for GI complaints. Had a colonoscopy in December. The prep was "better" than 10 years ago. The procedure was at the downtown office. All the health personnel were pleasant. The wait time was well represented. The procedure was done quickly and efficiently. I was home before I knew it. The office called the next day to check up on me.Results were about 1 wwk out and all is good.
