Leonard Weinstock, MD

Procedure Center of Irvine

To Whom It May Concern:

I have worked with Kevin Calisher and his ASC organization for the last six years. We joint ventured on an endoscopy center called the Advanced Endoscopy Center. This single specialty surgery center is located in St. Louis, Missouri and has been very successful since opening five years ago. The project was well organized from the beginning. The Calisher's long experience was invaluable in terms of the design, building, contracting and maintaining the center. They have done a good job handling the employees and helping the doctors achieve their goals in proving the highest of patient care.

As a busy gastroenterologist, I needed someone skilled in the day to day and long-term planning of my endoscopy center. The Calisher's were effective in this goal. Kevin Calisher in particular is fantastic at communication.

Our patient satisfaction questionnaires are ranked highly and we have passed all inspections without qualms. For some testimonials from patients, see our web site www.gidoctor.net and feel free to call me for any questions.

Sincerely yours,
