Dr. Keith Forwith

Dr. Keith Forwith specializes in thyroid and parathyroid surgery, treating patients with a wide variety of conditions including thyroid cancer, goiter, Grave’s disease, thyroid nodules, and parathyroid tumors. His focus on thyroid disease is rooted from personal experience as both he and his wife have thyroid nodules. He performs his own ultrasounds and FNA biopsies to ensure precision and accuracy. Always on the leading edge of the field, he offers minimally invasive surgery and in-office surgical alternatives.

His interest in research has led him to write some of the keynote articles in the development of novel sinus therapies, such as the Propel surgical stent and the Sinuva implant for non-surgical treatment of nasal polyps.

He has been among the first to adopt new technologies for problems as simple as tonsillitis to advanced problems such as thyroid cancer. Dr. Forwith was one of the first ENT physicians in the Louisville area to perform balloon sinuplasty – a less invasive alternative to traditional sinus surgery. His practice is focused on thyroid and parathyroid surgery, head and neck oncology, thyroid and parathyroid oncology, allergy, and sinus disease. He is the father of four wonderful daughters. He is an active member of his church and teaches a bible study at Southeast Christian Church. He is been married to his college sweetheart, Sue for 30 years. He loves all waters sports, including kiteboarding, slalom water skiing, snow skiing and hockey.


Dr. Keith Forwith began his career in research, obtaining a Ph.D. in biochemistry from Purdue University. He then attended Case Western Reserve in Cleveland, Ohio (ranked #23 by US News & World Report) where he finished at the top of his class and was selected into the prestigious Alpha Omega Alpha honor society. After medical school, he trained at one of the nation’s top ENT residency programs.
