Meet Our Doctors

Our original intention was to provide high quality eye care for low-to-mid income families in the Metro Denver area. We erroneously assumed that local efforts, such as Medicaid and the Denver Rescue Mission, were adequately serving the truly indigent market, and we wanted to pick up where those organizations left off, up to the demarcation for mid income.

After further market exposure, we better understand the difficulty for an individual to get an eye exam under Medicaid; due to a lack of Metro area providers, lack of ability to travel to outlying areas where Medicaid providers are accepting new patients, and qualification requirements.

Therefore, we expanded service to all un-insured families, with an income under $45,500 per year.

Jay S. Greenstein, O.D.

Dr. Greenstein was born and raised in Boston, Massachusetts.  After graduating from Boston Latin School (the oldest continual Public school in the country) he entered the University of Massachusetts graduating in 1970 with a Bachelor of Science in Psychology.  In 1972 he attended New England College of Optometry.  After graduating, he worked in Israel at the Hadassah Hospital in Jerusalem before being offered a position at the Iranian Medical Institute in Tehran, Iran.  His position there was to fit specialty contact lenses for certain post-surgical cases.
Upon returning to the States, he moved to Colorado in 1977 and opened his first office in Denver. In 1983,  he opened a second location in Littleton.  Both locations are currently still active...as is Dr. Greenstein himself. 
He was president of VOSH for 20 years, a service organization dedicated to bringing eye care to the underprivileged.  He personally has gone on over 20 volunteer missions to Mexico and Central America.  Most recently he has volunteered for "Von's Vision", a free clinic sponsored by Von Miller of the Denver Broncos.
Dr. Greenstein is an avid skier, snowboarder and guitarist. He now considers himself a confirmed Coloradan now, although his accent has persisted!  Dr. Greenstein is now semi-retired and in his spare time plays guitar to entertain residents of local nursing homes.
