Dr. Danita Sam, O.D.


Dr. Danita Sam, who’s infectious laugh can be heard throughout the office, has been practicing optometry since 1984.  She loves working with her patients and treats each patient as though they are her best friend.  She enjoys catching up with each of her patients during the exam and loves taking care of all their visual needs and keeping them informed of the latest treatments and materials available.  Children especially love Dr. Sam’s fun games and respond to her caring nature.  

She loves her profession and receives such gratification and fulfillment when she has made a difference in someone’s lives- whether it be for a student who hated reading and after discovering and treating a vision-related learning problem becomes an avid reader and an ‘A’ student; or the individual who was told they couldn’t wear contact lenses and proved them wrong.

Dr. Sam’s undergraduate education was completed at UCLA (Go Bruins!) and she earned her Doctor of Optometry degree from the prestigious UC Berkeley’s School of Optometry (Go Bears!). She has earned her therapeutic treatment licensure in 1996 and her glaucoma management and treatment certification in 2001. She has received an advanced glaucoma certification in 2014. She provides vision care for Cal State Northridge Athletes by providing vision correction, sports vision therapy, and sports eye-related injuries. She has been providing vision screenings for numerous schools and educational therapists rely on her expertise to help students with vision-related learning difficulties.

Dr. Sam is married and has two adult children-Her daughter is a dentist and her son is attending UC San Diego with an interest in Human Computer Interactions.  Dr. Sam and her husband have been together over 30 years and love to travel- exploring and experiencing new things. She’s known to be an adventurous cook- with some delectable (and a few inedible) results and loves technology music of many different genres.

Dr. Sam has been active in the community having served in many capacities and Board of Directors with such organizations as Soroptimist International of the Conejo, Canoga Park Chamber of Commerce, PTSA, United Track, and WHS Track/Cross Country Booster Club.
