About us

Our History

Sigma Pharmaceuticals, LLC is a wholesale distributor of ophthalmic supplies to healthcare professionals across the United States. The company was founded in 1985 by Dr. Gary Fisher, President and CEO, and Marcia Fisher, CFO, whose goal was not only to provide a wide variety of name brand and generic ophthalmic pharmaceutical & exam supply options, but also to meet the individual needs of practitioners. The knowledgeable and friendly staff at Sigma Pharmaceuticals makes every effort to provide one-on-one customer service, filling special requests for ophthalmic products not regularly carried. 

In 2007, Gary and Marcia's daughter, Nichole, joined the company as Director of Operations, ensuring that Sigma Pharmaceuticals remains committed to shipping only the highest quality ophthalmic products in a timely and cost-effective manner. Sigma Pharmaceuticals does not have a minimum order requirement and is proud of the fact that the company’s rates have remained competitive within the industry.
