ASC has something to say... THANK YOU!

Over the past 30 years, our company and the scope of our services have grown to serve a national market, but we still live by the same fundamental principles of honesty and integrity. Our philosophy has always been to produce an exceptional experience for our customers: patients, surgeons and our employees. Our centers consistently have set the standard for the best care and performance in the industry, performing over 200,000 surgical procedures annually. In the course of 30 years, that’s over 5 million eyes!
