About Dr. Jack Greenan

Jack Greenan, O.D., earned his Doctor of Optometry from Western University of Health Sciences in 2016. Before that, he completed his Bachelor of Science in Biochemistry at the University of California, Davis. Dr. Greenan is an optometrist at EyeTx, primarily practicing in San Pedro. He specializes in specialty contact lenses, particularly scleral lenses, and enjoys sharing his passion for eye care with his patients. His interest in optometry was sparked by his own experience with eye issues in his early twenties. Fortunately, everything worked out well, and he now enjoys great 20/20 vision. What he loves most about being an optometrist is engaging with people and helping them with their eye care needs. Outside of work, Dr. Greenan describes himself as a bit of a nerd, enjoying reading and anything related to science. His curiosity about the world and the universe is limitless. He also enjoys being in the water, perhaps influenced by his zodiac sign, Scorpio.
