Faculty Panel

Wouldn’t it be great if we just had a course where we could really talk about what is working and what is really just not working in our practice? Yes, and four years later we are still doing it.

Our faculty panel consists of highly talented and respected surgeons and healthcare professionals. However, this course is not about how great they are. We handpicked our faculty in order to provide a wide range of skills, techniques, and philosophies. Each of our faculty was picked because of their unique skill set, philosophy, patient population, and geographic area. This pushes the conversation and allows for open, candid discussion about what works well in our practices and, perhaps more importantly, what doesn’t.

Dr. Crall grew up in the Brunswick, Maine area. When he first visited the Eastern Sierra, he found a lot of similarities to Maine in the small town atmosphere with plenty of outdoor recreation.
