Dr. Shem truly cares for her patients of all ages but is especially passionate about treating and preventing vision problems in her pediatric patients with vision therapy and myopia control treatments. She absolutely loves to see her younger patients gain confidence as they improve their visual skills or excel in sports after being treated with orthokeratology!

Dr. Shem began her career practicing in the San Francisco Bay Area, then joined a long-standing ophthalmology practice in Honolulu, HI.

Dr. Shem has been a resident of the Pasadena area for over 15 years. She currently resides in Monrovia with her family.

Jonathan Kiriboon, O.D.

Photo of Jonathan Kiriboon, O.D.Born and raised in Southern California, Dr. Jonathan Kiriboon started his optometric journey with our clinic as an optometric technician. He soon decided to pursue his doctorate and he was accepted into Western University of Health Sciences College of Optometry, where he graduated with honors and is a member of the Beta Sigma Kappa honors society. After graduation, Dr. Kiriboon completed a residency in Pediatric Optometry and Vision Rehabilitation Therapy in Washington.

​Dr. Kiriboon has had extensive training in managing and treating various binocular vision dysfunctions, myopia (nearsightedness) control and ocular diseases. Having “good vision” is more than just the coveted 20/20 line, it’s also how well your eyes coordinate together, how well you can track a line of text without losing your place, and how well you can understand and make sense of what you see. These are all issues glasses alone cannot fix. Dr. Kiriboon is a firm believer in early detection and intervention for young patients that may have underlying visual needs.

By setting patients up for success early on, Dr. Kiriboon believes this will improve their quality of life down the road. Dr. Kiriboon is passionate about helping patients from all walks of life to reach their maximum potential.
