It's been a while since I had my eyes checked and I decided to try Dr. Gregg at Grossmont Walmart Vision Center. I am thankful to have found this clinic. Dr. Gregg was very professional, spent time explaining things during the exam process, and had me try on a few contact lens at home. His front desk person, Betty, was equally very friendly. Thank you for a great customer service! read more

I was in need of a new prescription for my glasses and contact lenses. 3 weeks ago, I went in to see Dr Gregg and his assistant, Betty. They were very professional and friendly. I was able to get my exam done thoroughly and it was inexpensive, since I do not have insurance, I paid out of pocket. Dr Gregg also gave me some contact lenses as samples to try. I would highly recommend anyone needing an eye exam to go see DR GREGG! Definitely worth it. read more

Dr Gregg is very friendly. He's a professional at what he does and you can tell he cares about his patients

Been going to him for at least 6-7 years now. He always has appointments available to get you seen quickly if needed. He's knowledgeable and nice and listens. Highly recommend. read more

The doctor was super pleasant! I had a wonderful contacts exam and enjoyed my visit, even though he puffed my eyes! Ha ha. I had to reschedule once and was running late, he accommodated my schedule anyway. He was super about the whole thing. Nice guy, quick and painless. He was easy to work with and it was a positive experience all the way around. Thanks, Dr. Gregg. Happy New Year. read more

Been going here for years! Always convenient and quick and thorough. Friendly staff usually.

Great experience. Dr Gregg is super nice and friendly, and so is his office manager Betty. He was very patient and helped me fix my vision !!! read more

I honestly don't know why I haven't written this sooner. I have been seeing Dr Gregg for several years now and even though I've since moved to the coast I still drive to La Mesa to see him. I have also referred several patients to him and they have been happy, too. I wish I could do an all-Yelp post asking reviewers to think carefully when they write reviews on small businesses. I think it is only fair to give them more than one chance before issuing a one-star review. I understand if the service is truly and consistently terrible but that is almost never the case. And in a medical practice it is always wise to approach the provider (not the front desk person and not via text) with concerns and allow them to rectify it, if possible. I will continue to see Dr. Gregg because he listens well, answers my questions thoroughly, and helps to keep my vision perfect! read more

I was in serious need of an eye exam and it slipped my mind for months now. So today I called this office since it was close to my house and work, I was told to come right in and at first I thought, that's not what I was expecting. So I literally headed right over on my lunch, and was in and out with my new prescription in less than an hour. No wait whatsoever. The office is located inside the Walmart. Super convenient! Very professional environment too. The receptionist was so nice and made me feel welcomed. Also I was the only person in the office at the time but there was tons of room for social distancing and sanitizer was easily accessible. The office is super clean and I felt completely comfortable. Dr Gregg was knowledgeable and explained everything to me in words I understood. I definitely recommend this office to anyone in need of an eye exam on the fly. Thanks so much! read more

With the onset of the pandemic I have been spending more time than ever on my laptop. When I had my appointment with Dr. Gregg he listened to my comments about there not being enough ideal computer screen distance focus in my progressive lens prescription. Dr. Gregg asked if I'd be interested in having a prescription optimized for computer screen time. I just got my glasses and they are awesome. My vision has never been more crisp and the eye strain I usually experience just went away right off the bat. Problem solved. Thanks Dr. Gregg! read more

I have been going with Dr. Gregg for years! My husband and daughter go with him to. He is very attentive I never feel rushed when seeing him. I would highly recommend him. read more

Dr Gregg is consistent and reliable! My daughter and I have come here for a number of years. He is friendly and easy to work with, and as one of the other reviews said - don't let the fact that his office is in WalMart fool you or put you off. He is very professional... and you could get a bit of shopping done after your appointment! Woot! read more

I've had several eye exams over the years at this office, conveniently located inside of Wal Mart. I've had nothing but positive experiences with both Dr Gregg and his staff in all the years I've been going there. Recently, I was browsing the eyeglasses at Walmart vision center when I found a pair I liked. When they checked their computer, I was shocked to learn that my prescription had expired. I literally had to walk just a few steps next-door to see if Dr. Gregg was available to give me an exam so I could get a new prescription. I filled out some papers and in about 5 minutes I was sitting in front of the Doctor who was, as always, professional, friendly and efficient. The woman who checked me in and checked me out was also friendly and very good at her job. When I came back an hour after my exam to ask for colored contacts samples she got up right away and grabbed me what I wanted. When I called back yesterday, several months after my exam, asking her to email me my prescription, I had it in about 30 minutes! A++ service and the lowest prices!!! read more

We love Dr Gregg and his staff! They consistently take care of my kiddo with all her glasses/contacts needs. Wonderful office, great staff and I know my daughter's eyes are in good hands here. Highly recommend! read more

I've been using Dr.Gregg for a few years, pricing is very reasonable and I LOVE that he puts the PD on the script. I've used him for contacts, glasses, kids and relatives for retina checks for diabetes. He's through and personable and pricing is very reasonable. Don't be put off because he's in Wal-mart, and you are free to take your script anywhere (I like Zeni optical myself.) read more

My family and I have been going here for years. The staff is personable, and attentive. I highly recommend going here for your eye needs.

I went to Dr. Gregg today and he was terrific. I had to wait a bit for my appointment but I could understand. The little old couple in front of me had some issues with their exams and I know the Dr. was super patient with them. I was tested and fitted with contacts and the price was right. I never thought I would be able to get this kind of service and eye care at Walmart of all places but it turned out to be a great experience. I would recommend Dr. Gregg with no reservation. Thanks! read more

We gave Dr Gregg a try (myself and my 7 year old) and he was great! I had to bring my younger child with us too, and he was so patient with the kids. He was thorough, calming and friendly. We'll definitely see him again. read more

My husband, friend and I have been seeing Dr. Gregg for probably six years. We recommend him to all our friends. He seems extremely knowledgeable about everything including other health problems that can affect your eyes (for me, Celiac disease causes dehydration, affecting my eyes) he always knows what symptoms I'm having before I even tell him and I reply, "Yes!" & am amazed he knew. My husband has had glasses for 35 years since he was a child, and he's never been happier with another eye doctor. His prescriptions are SPOT ON. His staff has changed through the years but they've all been lovely. Can't recommend him highly enough!! read more

Over the years I have been to 4or 5 different optometrists. This Dr. is great. Very professional, and takes his time. for me that was always the most annoying A or B A or B A or B. Just want them to slow the hell down. Also caught issue others missed read more

Wow! All I can say is that this guy is very legit. I've been going to him for years and he is the ONLY reason that I step foot into Walmart. Great guy, great service, and I always leave feeling happy and seeing more clear. The prices are extremely fair as well. 10 stars! read more

I have been wearing contacts and eyeglasses for years and have never had a Dr give me a wrong prescription until now saw Dr. Jeff Gregg. I ordered glasses and contacts under the prescription he gave me and soon realized it wasn't right. When went into tell them he reexamined and gave me a different prescription then the first but blamed it on the contact brand I was wearing for years. So he switched my brand to what he said was even "less expensive" one -which they were double the price and it was still wrong! Finally went somewhere else got the right prescription and switched back to my normal contacts! DR Jeff Gregg is NOT RECOMMENDED! read more

The only optometrist that's been able to get my eyes to 20/20. Very friendly and knowledgeable and provides you with plenty of options for contacts. I don't have insurance but it's very affordable if you don't have insurance. read more

Dr Gregg is very professional and knowledgeable. I trust him with my sight issues. Had a camera that can take retinal pics without dilating your eyes all day. Affordable , courteous, professional , what else do u need. read more

Super great guy! Really nice and attentive. We had a problem with one of my contacts so I had to return to see him and he totally fixed the problem and made everything much better. He really cares about his patients and he has a lot of patience with contact lens newbies like myself! read more

For us, Dr. Gregg Is A Must and we could not recommend him more. Testimonial: I lived in La Mesa for more than 20 years, but moved to Vienna Austria 25 years ago. My wife and I visit friends and family in the San Diego area almost every year. Whenever we visit, both of us always have a full check up on our current optical needs as well as full health check up on eyes. Dr. Gregg is extremely thorough and patient in our full examinations. Readers should note that they can take his prescription and go to any optical store of their choosing. Dr. Gregg will remain to be our only optometrist to examine our eyes on our yearly visit. read more

Dr. Gregg is very professional and friendly. I have been seeing him for a couple of years for my contact exam and prescriptions and have NEVER had a problem. read more

Great service for a great price! I saw Dr. Gregg in Feb. 2013, and really liked the whole experience. I was seen right away, and Dr. Gregg was kind, efficient and professional. Not only did he do a thorough examination but he took the time to answer all my questions and talk with me about the results. More like a boutique shop than what I've experienced at large places. I have reading glasses that i dont use, but with my new iphone, my eyesight seems to be getting worse. Turns out, I just need to use the glasses I have, so Dr. G saved me money. I liked his even-handed manner when he described my options for glasses. No "hard sells"! And I felt like he cared about my eye health. I'm glad I got a baseline digital imaging on my eyes and I'd recommend that service too. Nice! I'll go back again. read more
