Dennis E. Ratinoff, OD


Doctor Ratinoff’s primary interest in optometry centers upon preventative eye care. He has extensive experience in comprehensive eye exams, managing eye health conditions, co-managing pre- and post- operative Lasik and cataract patients. He also has a special interest in difficult-to-fit contact lens cases as well as computer vision testing. He’s licensed to treat glaucoma and any other eye health conditions.

Doctor Ratinoff started his education at UCLA where he was studying engineering. After a few semesters of focusing on the study he realized it wasn’t for him. He then transferred over to UC Berkeley where he obtained his Bachelor of Science and also received his Doctor of Optometry degree.

After graduating from UC Berkeley, Doctor Ratinoff joined the Air Force where his career took off. He was stationed at Wurtsmith Air Force Base in Oscoda, Michigan for 2 years. Once his service had been fulfilled, he and his wife moved back to Los Angeles for a couple years. They both missed living in the Bay Area so they decided to return in 1971 to buy a practice on Byron St. in Palo Alto where they raised their 2 children. A few years later he settled into his present practice on University Ave. and Middlefield Rd., University Optometry, established in 1983.

He is currently a Fellow of the American Academy of Optometry as well as a Vision Source Member.

He has recently taken on a gluten-free diet; however you will still find him sneaking a Girl Scout cookie here and there because he fully supports his granddaughters’ troops. He also loves a dark chocolate accompanied by his favorite, a large iced non-fat decaf extra shot latte.


Dear valued patients:

We love our patients and the work we do so very much. While we are sad to think we will have to miss seeing your beautiful smiles for the next few weeks, protecting the health and safety of our patients, staff and the members of our community is of the utmost importance.

In response to recent recommendations from the California Optometric Association and the local government for limiting the spread of COVID-19, our office will be closed for three weeks, effective today – Monday, March 16 – at 4pm. All regularly scheduled routine eye appointments will be cancelled. Our team will reach out to those impacted to reschedule.

If you need assistance with ordering or picking up CLs/glasses, please email us at or text us at 650-766-6655. We will be checking both emails and texts throughout the day, but please be patient with us in getting back to you. If you are experiencing an eye emergency, please text us at 650-766-6655. We will do our best to get back to you in a timely manner. If you do not hear back within 30 minutes, please go to the local urgent care or the emergency room.

Thanks for your patience with us as we try to work through this. Stay tuned for updates via email.
