Kind words from our patients

Dr. Berthelsen is so great! He and his staff are personal and professional, and take time to listen. I went to him for an ingrown tail, callus, and arthritis developing in my toes. He went through all my options patiently and painlessly cut out the nail and callus. I highly recommend him!

My husband and I have been going to Dr. B for years for various foot issues and surgeries. He is the best and so is his office staff!!

Clean, professional with courtesy

Charles B.

Great experience with Dr. Luke and would highly refer. Takes genuinely good care of his patients. Had a few visits so far, and in each visit Dr. Luke took good care of the foot, answered all our questions with detailed/helpful responses, and addressed long term care and recovery. He will not recommend a procedure that other doctors might, because its covered by the insurance. His new staff Janene Pinkyene (pronounced Pink-knee), is also a good addition to his team.
