About Our Optometric Centers
At all our partner practices — La Paz Optometric Center, Brookhurst Optometric Center, North Tustin Ave Optometric Center, and Mission Viejo Optometric Center — our team members share a vision of a world where all our patients can see clearly and worry-free. That’s why we’ve become experts in our field, learning cutting-edge technology and techniques to help you maintain crisp, comfortable sight for years to come.
Our Mission
For nearly five decades, the teams behind our optometric centers have been committed to providing your family with lasting eye health and clarity. While we’ve expanded our staff, services, and locations over the years, our overarching mission has never wavered: to give each patient a clear view of their life using customized, technology-assisted care.
Our friendly team members use their passion and expertise to deliver comprehensive services you won’t find at other practices in the areas we serve. Not only do we collaborate with each other, we collaborate with you. You’ll play an active role in your eye care and we’ll thoroughly talk through your test results and potential solutions so you can leave with a complete understanding of your vision health.
Our History
Since our first optometric center opened its doors in 1973, we have provided a first-rate, personalized patient experience. Each of our practices embraces the mission and core values we’ve prioritized since day one. We’re continuing to add technology, establish new practices, and work with each other to improve your experience and eyesight.

Our accomplished doctors come together to deliver on their promise of providing unmatched vision clarity. They use the latest tools and techniques to thoroughly assess your eye health, all while working closely with you to explain how our solutions can help and to determine which work best for your situation. We’ve got you covered — whether you need to update your prescription, manage an eye condition, or anything in between.


See What Our Patients Are Saying
Ordered a new pair of glasses and couldn’t be happier with them. Finally a prescription that I can read with. Needless to say, I’m very happy!
This was my second time there. I will be going back.
Thanks for the gift of better vision
Every person I encountered was professional and a wealth of information. There were so many options that I left there feeling that they care and they want to find the best one for me. I was very impressed and went home telling my husband about it.
1. The ease of online appointment scheduling and patient forms
2. Friendly staff at the reception area
3. Technician administering visual tests extremely knowledgeable and friendly.
4. Dr. Michael Lum clearly explained my results and my options so that I would receive the right prescription for my multiple visual needs
5. Huge selection of frames to choose from which could have been overwhelming but Erin hand selected many for me to choose from and between us we were able to quickly find the perfect pair.
I have never been excited to go to for an eye exam or to pick out glasses but I now look forward to my appointments at this office.
Dr Yamamoto is great. He takes the time to answer questions and doesn’t make you feel rushed.
Amelia helped me find the perfect pair of glasses and was really patient with me.
I’d recommend this office in a heartbeat!
I am a kind of person oriented to details and I have hard time to make up my mind especially when the store have a large selection of frames. They also search on internet the frame i wear now, they found it, ordered it will not pay for in until I am satisfied.
They are absolutely wonderful!
I strongly recommend this office of Mission Viejo Optometric Center.

So glad that I found my optometry center.
The most highly recommended vision center. If there was more then 5 stars I would have definitely gave it to the team.
That’s the place you should go to if you want to walk out with a smile on your face. They magically know how to draw a fat one on your face.
Dr Justine Hsieh is the best!
Very knowledgeable and informative. Been coming to this office for years, and I'm always impressed by the professionalism and friendliness I experience.
Hseih is very thorough and personable. In fact, their whole staff is excellent.
The office also has a wide selection of glasses to choose from. The whole team (including the doctor!) were happy to help give their input so I could select the frame that best fit me.
Would recommend this optometry office to anyone wanting to get an stress free eye exam with a great office attitude and friendly faces!
I booked my annual eye exam, and was going in feeling comfortable. On our call, Jody had asked me to make sure to bring my mask and to fill out some paperwork via email prior to my appointment, to reduce contact and time spent in the office. Upon arrival, I was asked to call the front desk to assure that I would be socially-distanced and everything was cleaned before entering. Once entered, Jody took my temperature and then walked me through some eye tests. She made sure to wipe all of the equipment down before use, which was very assuring. I then walked into my exam, and there was a sign on the chair before sitting down stating that it had been cleaned. I had an eye exam with Dr. Hsieh, and was extremely happy with her professionalism and knowledge. We ended up trying out some new contacts! James checked the schedule and had me book a 1-week follow-up appointment to make sure that they were to my satisfaction before ordering them.
I came back a week later with no problems, and ended up purchasing a year supply of contacts (which were shipped to my house promptly - in less than a week).
Overall, they are one business that is following COVID guidelines well, and I will continue to give them my service!
Dr. Chi's office uses state of the art equipment to aid in the examination process and this ensures that you do not need to have your eye dilated.
Dr. Chi's staff is friendly, caring and knowledgable. Maria, Jakub, Samantha and Lina put us at ease and walk us through the selection of frames, explain lens options and costs and also what our insurance will cover. We are very happy with Dr. Chi and his excellent staff.
I would definitely recommend this optometrist
Staff is also very friendly & helpful.
In addition, we have experienced the staff to be very professional, patient and kind when calling to change or make appointments. Also when checking in to be seen.
The office is very clean
I was greeted by Jacob who was warm and welcoming. I explained my vision problem and he asked if I wanted to be seen today. I said “yes”. Jacob checked my insurance and explained me the tests that would be performed. He was so kind and helpful. I was seen 30 minutes later and had a full eye exam and was fitted for contacts. I was so thrilled. I was seen by Dr Chi. Excellent Optometrist. He was very patience with me and explained and answered every question I had. He even assisted me by plucking sn ingrown hair from my eyelid. Wow! I checked out with the girls who were delightful . I had the best experience. The entire office staff was friendly and very helpful. Stop by and see them! You”ll be happy you did.
a new frame. They treats me like a family instead of another patient. Not having to dilate this year because of the tech they have might be one of the best part.
