Dr. Schuster and I were very satisfied with our Duet training with Dr. Seiler. He arrived on a timely manner as agreed upon. We started with a didactic session for an hour and saw clients for the remaining of the day. Dr. Seiler was extremely professional and informative with me. It was beneficial to me that each of my clients presented a different body area to treat which allowed him to show me different positioning techniques. I am pleased to learn that the HS head can treat the majority of the body! He spent extra time with me in sharing his knowledge on the use of our Lumenis One as well. He promptly followed up with the material he promised to send me and extended an invitation to call him with any questions or concerns I may have.
