Dr. Hahn has worked part-time at Natick Eye Associates, at all locations, since 1997. Prior to this, he received his undergraduate degree at Franklin & Marshall College. He then went to Brown University and received his Ph.D. studying perception and psychophysics with an emphasis on color vision perception. While training for academia, he decided he wanted a more clinical career and then obtained his O.D. from the New England College of Optometry. Dr. Hahn then completed his residency at the Brockton and West Roxbury VA Hospitals.
Dr. Hahn and his partner Stephen have been legally married in Massachusetts since May 2004. They have four parrots, all of which were adopted from Foster Parrots, a local shelter for unwanted, abandoned, or neglected parrots. They have been very active with fundraising and volunteering at Foster Parrots and are thrilled to see that Foster Parrots has been able to open a larger sanctuary facility in Hopkington, Rhode Island. They have also been very active in gay and lesbian causes.
In addition to his family, Dr. Hahn enjoys running, working on his house, and NY Times crossword puzzles.
