Dr. Gasser is the most skilled, intelligent and absolutely the most caring and compassionate orthopedic and medical doctor my husband and I have ever experienced. He has taken me and my husband, from not being able to walk without a cane due to being bone on bone with our knees, and put us on Euflexxa gel injections for the past several years. My new x-rays shows that since the first round of injections, there is no further decline in bone on bone in my knees. He has ensured through persistence with his medical knowledge that this particular gel was imperative for my well-being. My husband and I have a great quality of life due to Dr. Gasser. Thank God both Medicare and my BCBS Federal Plan approves Euflexxa. His assistant Kathy always ensures that she returns my phone calls and gives me truthful guidance and assistance. While she is truly taxied with helping all of Dr. Gasser’s patients, she always does it with her beautiful smile. His staff always gives professional and caring help by always being right there to help. Director of Quality Assurance, Kathy Denemark, oversees injections and truly does her best to help and answer my questions.

Dr. Gasser is to the point, in medical care, because he knows what he is doing. We trust him with our knees and if surgery was ever required, we would trust him with our lives. Thank you Dr. Gasser and Kathy for being our medical team.

As usual, great experience. I am a retired physician and have had surgeries, injections and complete testing of my joints. I believe FOI has the edge in all of the Southeast United States. What many patients do not realize is it is a teaching institute for international doctors and allied health care professionals. Their staff continues to grow with additions of outstanding doctors from across the states. Really no better place to go. Dr. Gasser is at the top of this wonderful staff.

By far the finest orthopedic surgeon in Tampa. He has operated on me several times for injuries I have suffered over the years and I have had excellent outcomes each time. He is a skilled clinician and surgeon. I would recommend him to any of my friends and family.

Thanks to you and your team, I am back to 100% with my right shoulder. I am so grateful my dear friend referred me to you for the impingement in my right shoulder. Wishing you and your family a beautiful 2019!

Dr. Gasser is a phenomenal physician. When he’s in your treatment room it is as if he has all day to speak to you. I brought in a previous surgery report for something and he took the time to read it word-for-word, and then thoroughly explained the procedure I’d be having with him. It is evident he enjoys what he does, which is so rare among other doctors where you are treated as part of the daily quota and nothing more. As a whole, FOI does a great job! I am a Practice Administrator myself, and have used my experience at FOI as a catalyst to improve some things in my own practice locations. Thanks for all you do!

Dr. Gasser fixed my torn rotator cuff and ball joint that had rough spurs from artheritis.
My shoulder was completely repaired by Dr Gasser and works just like new. Full range of motion, no pain, just perfect. Dr. Gasser showed me before and after color photos of my shoulder mechanisms
and the MRI and or CT scan pictures showing his excellent work were amazing. The rough ball was polished smooth as glass, the tears were trimmed and stitched together. He sent me to therapy and within 4 to 6 weeks my shoulder was back to as new condition and swimming. I strongly recommend Dr Gasser and the Florida Orthopedic Institute to anyone that has shoulder or knee problems.

I dislocated my shoulder and was referred to Dr. Gasser (the shoulder guy) and am so glad that I was. Dr. Gasser and his staff were not only quick and efficient with a plan of action but followed me literally from day 1 to even now in my recovery with physical therapy. I am confident without an once of doubt that I have received the most comprehensive care that I have ever had or witnessed. Dr. Gasser always gave me the utmost concern and regard while in his care. Knowing he has done hundreds of surgeries and dealt with athletes, he never made me feel anything less than a professional athlete myself. Dr. Gasser stated that my injury was one of the worst he had seen in his many years of practice. The follow up from Dr. Gasser was nothing less than stellar and he continued to do so until he was positive that I was healing properly and was clear from any chance of infection. Dr. Gasser and the staff at Florida Orthopaedic truly define excellence in medicine and made what was already a traumatic and stressful situation manageable and a pleasant circumstance apart from the injury itself. You can rest assured that your health and best interests are being taken care of. There is no other place I would trust with our families care in the future than Florida Orthopaedic Institute and Dr. Seth Gasser.
