I’ve been seeing Dr.Mantas for a few years now and he’s always been great. He takes the time to answer all of my questions, offers a variety of treatment options and is easy to talk to.

His staff is friendly and accommodating. You can even do video consultations.

I was recommended Dr. Mantas by a friend. Online reviews were strong and my appointment with him didn't disappoint. He is great doctor! Very thorough!.

Nice doctor. Seems very knowledgeable and insightful. My endoscopy found pre-cancerous changes in my stomach along with a H. pylori infection and early ulcers. With my family history of stomach cancer I am glad I got it done. He treated the infection and my symptoms are resolving. Thank you Dr. M!

Thoroughly enjoyed my entire healthcare experience with Dr. Mantas from A to Z. His staff was attentive and Dr. Mantas was easy to talk to you, caring and knowledgeable. My colonoscopy went great! My family and I thank you!

I enthusiastically recommend Dr. Mantas! He did my screening colonoscopy and saw my husband for his digestive issues.

Really nice doctor! Found my colon polyps and now I no longer have rectal bleeding. Thankfully no cancer!

I had a long history of constipation. I saw Dr. M by the urging of my friend. He did a thorough work up and now I feel great!

My friend recommended Dr. Mantas for my screening colonoscopy. Really nice guy and his facility is great!

It is with great pleasure that I write this glowing review for Dr. Mantas! He performed my screening colonoscopy and did a superb job! The prep was easy and the center was accommodating! I recommend him to anyone in need of colon cancer screening or digestive care!

I was having severe heartburn for nearly 5 years despite various treatments. I finally saw Dr. Mantas who did an endoscopy and found that I did not have reflux as the cause of my heartburn but rather something called eosinophilic esophagitis. So glad I found Dr. Mantas! We started treatment and I am feeling great!

Dr. Mantas did my screening colonoscopy and I would highly recommend him and his center at Old Town! They did a great job and I felt like I was in the best of hands!

Dr. Mantas performed a colonoscopy on me last week. I was very nervous about it and dreaded it doing for several years. However, when I arrived at his center, the staff was very reassuring and friendly. Dr. Mantas and his staff took their time making me feel comfortable and relaxed. The colonoscopy went great! There are a lot of misconceptions about the procedure. The bowel prep was quite easy and I was entirely asleep for the procedure. I really felt fine afterwards but took the rest of the day off. I would highly recommend having the procedure done because it isn't nearly as bad as I thought. I would also highly recommend using Dr. Mantas and his staff to perform the procedure. Thanks Dr. Mantas you are a true professional.

My family and I were so pleased with Dr. Mantas! He came out of his way to help us at a hospital he normally does not work at. He was so kind and thoughtful! My endoscopy and colonoscopy went smoothly. He found my problem and I am on my way to recovery!

Thank you Dr. Mantas.

Had my first colon cancer screening colonoscopy last week with Dr. Mantas. He just called me with my results. Everything went well. He was really nice!

Would highly recommend him!

I am grateful for Dr Mantas because I know I wouldn’t be here today without him doing my colonoscopy and finding and removing my large colon polyp. I was having abdominal pain and blood in my stool and a friend recommended Dr. Mantas because of his experience and kind bedside manner. Thank you so much for taking great care of me!

I have been seeing Dr. Mantas for the last six months for stomach issues that I had been suffering from for nearly 2 years. He performed a comprehensive work-up and we finally got to the source of my problem. Now after starting treatment I feel great. Can’t thank Dr. Mantas enough! He his staff are very attentive, knowledgeable and caring. Wish I found him sooner ☺

While out on the golf course one day, I indicated to a friend that I was having trouble with acid reflux. He was a patient of Dr. Mantas and highly recommended him. I decided to make an appointment and was seen in a very timely manner. After examining me and scheduling some routine tests, it was in fact determined that it was just a simple case of acid reflux. Dr. Mantas prescribed a medication that has completely taken care of the problem. I appreciated the fact that he was very thorough--running tests to rule out other things and not just prescribing medication on my symptoms alone. I have the utmost confidence in Dr. Mantas and was very comfortable with him. I will continue to see him and will highly recommend him to my peers.

Dr. Mantas performed a routine colonoscopy on me. He was very thorough in explaining the procedure to me beforehand, and very detailed in the follow up. The procedure went extremely well and I was very impressed by his knowledge. Dr. Mantas is a very patient man, and made me feel very comfortable.

I made an appointment with Dr. Mantas for stomach pains I had been having on a regular basis, but was unsure of the cause. Dr. Mantas saw me on time and was very patient with me; he answered all of my questions, suggested affordable options for treatment and scheduled a follow up appointment to see if my symptoms improved, which they did. I have not felt this well in a long time, and something I thought I would just have to live with has now been completely resolved. I would recommend Dr. Mantas to any of my family and friends, as he is very knowledgeable in all aspects of medicine, particularly his specialty. He and his staff are very professional and I can say with certainty that I will go back to Dr. Mantas for my routine GI exams in the future.
