Our Eye Doctor

Eye care professionals specialize in understanding how the human eye really works, as well as diseases and conditions that affect your vision – many of which do not have obvious symptoms. Eye doctors know how age and risk factors affect vision over time for young and old, and they understand the benefits and features of corrective lenses including eyeglasses and contacts.

Our optometrist takes the time to explain the results of your eye exam, describe your options and listen to your eye care needs. Because maintaining good eye health is an ongoing partnership, we encourage you to ask questions and share your health information, which could be vital to monitoring, diagnosing and treating potential vision problems.

Dr. Parungao is originally from Des Plaines, Illinois which is about 20 miles northwest of Chicago. She received a Bachelor of Science in Biology and Chemistry from Northern Illinois University in 2003. She decided to pursue a career in optometry in her freshman year at college. She chose optometry because, wearing contact lenses she was always in the optometrist's office and enjoyed learning about the profession.

Dr. Parungao received her Doctor of Optometry degree from the New England College of Optometry in Boston, Massachusetts in 2008.  In 2009 she relocated  to Los Angeles, California and completed a  residency at the Los Angeles Ambulatory Care Center at the Veteran’s Affairs Outpatient clinic in downtown Los Angeles. Her specialty is in ocular disease and low vision rehabilitation.  She also enjoys seeing children in the office.  Dr. Parungao also keeps up with the latest in technology and eye care by regularly attending continuing education classes.

When she is not in the office seeing patients, Dr. Parungao enjoys an active lifestyle which includes travelling, working out, running, hiking and snowboarding.  Ask her about running marathons sometime.  She also enjoys a good book and is learning how to play croquet and play the guitar.

Jonathan Mak, O.D.

Dr. Mak was born in Vancouver, Canada and moved to Simi Valley with his family before his 9th birthday. It was in Simi Valley that he was prescribed his first pair of glasses likely because of his voracious appetite for books and video games. He always looked forward to his eye exams growing up. Dr. Mak pursued an undergraduate education at the beautiful University of California, Santa Barbara. He earned a Biochemistry degree in 2011, graduating with Honors and Dean’s List distinction.

Dr. Mak completed his Doctor of Optometry degree from University of California Berkeley School of Optometry in 2017. Dr. Mak is skilled at glaucoma management and able to prescribe therapeutic pharmaceutical agents (TPA) to treat many ocular diseases. His training includes a rigorous apprenticeship program in large hospitals like VA Palo Alto and Kaiser Permanente Sacramento as well as in organizations such as Prevent Blindness Northern California. Dr. Mak especially loves helping children and young adults develop fantastic vision so they can achieve their dreams.

Like a good Canadian, Dr. Mak enjoys watching hockey and is learning to skate so he can one day play. On the weekends, Dr. Mak takes advantage of California’s glorious beaches and hiking destinations to catch a few rays. Dr. Mak also loves to invite his friends over for board game nights for some friendly competition.

Dr. Mak is a member of both the California Optometric Association (COA) and the American Optometric Association (AOA).
