Dr. Casler is an amazing surgeon!! He was able to remove the Lymphangioma that had grown all through my neck. I went to 3 other doctors and all told me that type of surgery was out of their league. He’s also a certified plastic surgeon, so my scarring is minimal, which is amazing considering the depth of my surgeries. I’ll be forever grateful to Dr. Casler!!!

Dr. Casler is a wonderful doctor/ surgeon. He recently performed a total thyroidectomy on me. Before deciding to go through with the surgery he answered all my questions and did not make me feel rushed. After surgery he has answered any questions I may have had with the help of his team. He contacted me with pathology results as soon as he recieved them, didn't keep me waiting. I defiantly would recommend him to anybody needing surgery. GREAT DOCTOR! Thank you!

Couldn't have asked for a better dr. to perform the surgery for my thyroid! Dr Casler took the time to really explain my condition into detail and made me feel comfortable through the visit. More important, as I needed to have surgery, he was very patient with me and made me feel confident that everything will be fine. Feel very fortunate that dr. Casler did my surgery. The best thyroid surgeon in Jacksonville.
