Mariusz Klin, M.D., Ph.D

I saw Dr Klin this week for the first time. He took the time and talked to me about my possible issues and he listened to everything I had to say. You could tell he cared and wants to help. Everyone in his office was really nice too.

Dr. Klin is a great doctor!! He takes great care of my husband. The wait time is not too bad either. Office staff is really friendly, too! Highly recommend !!!!!

Very kind and patient physician .
Front office staff always so professional, very busy office and it runs pretty smooth

My experience with Dr. Klin was great. He even left the room during our consultation to make sure my new insurance would cover a colonoscopy at 45. The day of the procedure he made sure I wasn't fretful before going under Anesthesia. Every interaction has been positive.

I had been sick for 3 months and the doctor I was seeing at the time was not able to provide a diagnosis or any help. I called Dr. Klin's office on a Thursday, got an appointment for the following Monday, they scheduled two procedures for Wednesday (2 days later) and I had my diagnosis the following Tuesday. Everything done in less than 2 weeks! Now, I'm feeling 100% better and it's all thanks to Dr. Klin and his staff! I could not be more pleased! I highly recommend him!

Love the wonderful staff. Dr. Klin is very attentive and caring.

The first visit was a bit shaky! Dr may have had an off day. Had the procedure, went inn for follow up, Dr was pleasant and very friendly and informative! 2 HR wait for appt.

Dr. Klin is an exceptional doctor in his field. I moved here from Dallas, Texas, and have had serious gastrointestinal issues for a very long time. Through Dr. Klin’s care, I am pain free for the first time in many many years. Dr. Klin listens carefully and works diligently to get to the underlying cause(s) of your issue(s). He has a very efficient and friendly front office staff and very kind nurses. The team he uses when performing medical procedures ensure you are well taken care of, made as comfortable as possible, and treated with much sensitivity and care.

Dr. Klin is one the only Doctors in our area to actually take the time to look at all of my health needs before deciding on an action plan. I am so grateful for his patience and time to help me be healthy and active again! Could not ask for better care by the staff at his office and his Surgical Team! Thank you for taking care of Bay County in Panama City Florida!

I have been sick for over 3 years now with gastro issues. Went to numerous doctors and was diagnosed for the wrong thing . I have been in pain for over 3 years , everyday I would have to take nausea medication just to be able to get up in the morning and numerous times through the day. I lost over 40 lbs also because I had a stricture in my esophagus , I couldn't eat because I always felt full. I also couldn't have a BM . Dr. Klin saw me and asked me everything that was going on , I told him all my problems and he had me in the surgery center the next week, unlike the other doctors I had seen they wouldn't do all the procedures at once Dr Klin did. He also did an ultrasound of all my organs to make sure they were all good. Now since I've had all this done I feel like a new person. He fixed everything in 1 visit , I feel 10 years younger. I can now eat anything I want. I can use the bathroom , I haven't had to take any nausea medicine since the procedures. Dr Klin is a miracle God put on this earth for a reason. His staff is amazing , these people actually care about you, your not just a patient , you are their primary concern when you are with them. I honestly thought I was dying and now like I said I feel more alive than I have in such a very long time. I thank God I found Dr. Klin cause I was at the end of any hope of being fixed. If you are having any gastro issues I would strongly suggest you see Dr Klin. DR Klin you and your staff are life savers. Thank you so much for making my life worth living again. See you in a August.

Dr. Klin is the only doctor who was able to diagnosis and treat my debilitating gastroenterology issues. I am able to eat all the salads and vegetables I love again. More importantly, I am to leave the house and able to work again. I wish I could give him 10 stars. Yes, I have had to wait to see him as others have stated in their reviews, but it was so worth it. You have his undivided attention when it's your turn, so don't let waiting stop you, if you really need a great doctor.

Dr klin he's been my doctor for the last 15 years. He's treated some of my family members in the past. He's a very compassionate man very professional he knows his stuff. He has a great team in office and in the surgery center where I attend. I'll keep going to him as long as I need to.

I have been seeing Dr Klin for about 10 years. People complain about the wait time in his office but in my opinion it is well worth it. You actually see him and not a PA which means a lot to me. Dr Klin also listens to you. If you have a problem a problem anywhere in the abdomen he will find it. Thanks to him, Renal Cell Carcinoma was detected in time to get the kidney removed along with all of the cancer. If he hadn't listened when I told him there was something wrong it may not have been found until too late. Thank you Dr Klin and your marvelous team.

It has been my experience while interacting with Dr. Klin that he is a Dr. of extreme respect and empathy. I felt he was genuinely concerned. I did not feel pressured into making any decision I did not feel comfortable with. Dr. Klin is my top recommendation if you or your family needs a Gastroenterologist.

Dr. Klin is one of the best Doctors that I've ever had the pleasure to meet & work with.. Thanks Dr. Klin for caring about your patients..
God Bless

I am so very grateful for Dr. Klin and his staff. I had been seeing another G.I. Group in Panama City, FL and, was getting worse rather than having any improvement in my condition. I saw Dr. Klin and he said I think I can help you and, he certainly did. Very professional, kind and, cares about his patients. He is a very hard working Doctor and, I am very happy to have him as my physician. I do believe that had my husband not recommended that I try to contact this doctor I would have already been dead because the other group I was going to for help didn't have a clue as to what to do. I highly recommend that if you are having GI problems. Get an appointment with Dr. Klin as soon as possible. You will be glad you did. Also, I would like to add he is a very busy man and, your wait may be several hours. He is worth the wait. He will help you. I give Dr. Klin and, his staff a 5 star rating. Thank you so much Dr. Klin.
Kindest Regards,

I have read the reviews and I understand the long wait time. I agree, the number of patients could be decreased for less wait time. However, in Tallahassee I was told after being prepped for a colonoscopy, that the doctor couldn't finish the procedure. It was a huge problem & I was told I couldn't have anymore colonoscopies. Dr. Klin said he would be able to do the colonoscopy. And thank goodness he knew what to do. I had polyps and he found other issues! Had he not done so, I don't know what would have happened to me. I am grateful for this doctor and his staff!

Dr. Klin and his staff are extraordinary! He is very kind, attentive, and professional! His staff, both in his office and at the surgical center, are fantastic!

Needing to have this type of work done is stressful enough without the doctor and staff being completely soulless, which was the case at another doctor's office I was referred to by the Tyndall Clinic. I won't name the other doctor, but his name is similar to the sound a lion makes.

If you have a choice for your gastroenterologist, insist on seeing Dr. Klin!

I am a registered nurse and a patient of Dr. Klin’s and so are many of my family members. I want to say to everyone that if you are looking for help with a GI problem or screening colonoscopy “that will remove every polyp” you will get it with Dr. Klin. You will see the same doctor at every visit and not someone who was just trained by the physician on the job. He is an excellent doctor and his diagnostic, intellectual, and interpersonal skills are superb! Only people seeking pain medications may be disappointed. I would like to just say again that he is a very nice human being and above all an excellent doctor!
