"Dr. Leffingwell is a 5 star physician of the highest order"



"In short, Dr. Leffingwell demonstrated why physicians are often held in high regard. His competence and manner were very reassuring under difficult circumstances. As the "on call" doctor for his partnership, he stepped up, and, within about an hour altered my anxiety level from about 8 or 9 to around 2. Without the benefit of an assistant/nurse he performed brilliantly in alleviating my post surgery (deviated septum repair...) excessive bleeding."



"Dr. Leffingwell and his staff are Professionals. They quickly worked me in, diagnosed the problem, and explained everything. I started all prescriptions within 2hrs of the appointment which fixed me up in a week. Thank you!"



"This was my first visit. Everyone was wearing mask, they were very professional and knowledgeable about what I was there for. I left feeling like I will be able to resolve my issue."



"Over the years I have developed some abdominal and back fat that I have not been happy with and have not been able to lose with dieting. I am typically anti-plastic surgery. But I learned about laser Lipo from a friend who referred me to Dr. Leffingwell. After speaking with Dr.Jim and his staff I was more intrigued. They answered all my questions and shared with me exactly what to expect. I decided to get this procedure because it was less invasive. The procedure was exactly how they described it and it was very simple. I was out of the office in a couple of hours. The results are amazing and I wish I had done this years ago. But the timing in meeting Dr. Leffingwell and his staff couldn’t have been more perfect. This dude is very happy with the results. No more love handles for me. I can’t wait until the summer to get some sun on these new abs. Thank you Dr.Jim !"
