I am deeply disappointed with the unprofessional customer service experienced today when dealing…read morewith an appointment for my employee. Our employee arrived for his scheduled appointment today, but his necessary translator did not arrive. When I called to resolve the issue and suggested reaching out to the insurance carrier to see if there was a coordination mix-up, the representative, Shana, became extremely aggressive and rude on the phone. Instead of providing the customer support we needed, she claimed there was no one available in the entire building who spoke Spanish. Throughout the call, she refused to let me get a word in. When I politely asked for her supervisor's name, she completely bypassed my question and hung up on me, refusing to provide any management contact information. I called back immediately and was connected with Brandy, who was very kind, professional, and helpful. She was able to provide the name of the supervisor, Denise Kurt. While I appreciate Brandy's excellent assistance in a stressful situation, the behavior exhibited by Shana is completely unacceptable for a professional medical office handling sensitive worker accounts. Management needs to address Shana's conduct and communication immediately

Unprofessional and Disrespectful of Patients' Time…read more My mother's appointment was scheduled for 1:20pm, yet we were kept waiting 51 minutes before being seen. There were no updates, no explanation, and no apology from the staff or the physician. When I mentioned--calmly--that my mother's time should be respected and that appointments should begin reasonably close to their scheduled time, Dr Gilbert replied: "Well, sometimes it works that way and sometimes it doesn't." That statement, paired with a complete lack of acknowledgment for the delay, was unacceptable. It reflected a dismissive attitude toward patient time and basic professionalism. I remained polite and civil throughout the interaction, but left with the impression that punctuality and patient communication are simply not valued here. If you expect respect, accountability, or even a simple apology for excessive wait times, I would advise seeking care elsewhere.

I cannot recommend Dr. Lim highly enough!!! 17 thumbs up!!!…read more She is a miracle worker. I was the biggest scaredy cat about getting my cataract surgery done. I have been wearing glasses since the third grade and I am extremely near-sighted. One of my biggest fears is losing my sight. Dr. Lim made me feel extremely confident about getting the surgery. She explained the surgery in detail and she offered excellent advice about the right type of cataract lenses for me. The surgery itself was extremely quick and painless. I felt like I was at a Laserium show at a planetarium and not in an operating room. There are a number of follow-up appointments scheduled for the day and week after surgery. Both Dr. Chan and Dr. Zhang were caring, knowledgeable, and friendly at these follow-up appointments. The Walnut Creek office staff is also wonderful, friendly, and efficient. Being the nervous Nelly that I am, I did call them more than a few times with my worries. I am now seeing 20/15 out of my distance eye. I can read 4 point type out of my reading eye. I feel I should be on a lecture tour, wearing a Super Hero cape to match my new bionic eyes, touting the wonders of cataract surgery with Dr. Lim. The only regret I have is enduring blurry and dimming vision for a year because I put off my cataract surgery because I was so scared.

She is a one in a million genius eye surgeon with a manner so unassuming and a hand that is so calm and self assured, you pray that she is there whenever you go under the knife. Period! Her specialty is corneal implants. She loves what she does and she loves to give the miracle of perfect sight to her patients. I'm 77 now and one day after the surgeries my eyes tested 20/20 & 20/24. Three year later they still test the same. I'm so grateful to her! It is not surprising to me that she worked with Dr Vastine, the Errol Flynn of eye surgeons. And she was referred to me by Dr Litwin, one of the best. Don't even think about it. Get on her waiting list today.

I visited the Pittsburg clinic and from start to finish an all around great experience. All the staff was friendly, professional and attentive. I was seen in a very timely manner. The physician, Dr. Wang was thorough and explained my condition very clearly to me, answering my questions. The building is older, with a shared waiting area, but it was clean and not overly crowded. I will be staying with Dr. Wang and their team for any needed follow up. I would recommend this practice.

He was already running late, it was 3:45 when I overheard him. When he finally got to my appointment it was 3:55, now he's rushed. He dilated my eyes then proceed to give me an eye exam. I knew that was incorrec since my vision was blurred from the dilation. I called them back a few weeks later and explained what happened with Dr. Meng, they scheduled another appointment with a different Dr. to double check my vision prescription. Sure enough there's a big different. Furthermore, I was charged for both appointments. When I left the office they schedule a one year follow up. A few days afterward, I called the office and canceled the appointment since I no longer trust their provider's care. Fast forward a year later, I get a call from their office to remind me of my upcoming appointment which I canceled a year ago. I missed their call and they left me a voice mail, I picked up the voice mail within seconds after missing their call and called them back, 15mins prior to closing and the incoming calls were directed to their voice mail, I get it it's Friday. I left a message explaining the appointment was canceled and request for a call back to confirm. Monday morning I called to ensure they cancel my appointment. The first time I called they informed me two calls were ahead of me and put me on hold after ten mins. I hung up. I called back several times during the day and their voice mail indicated they were busy and directed calls to call their other locations if it's an emergency. I realise cancelation is not an emergency, but I do not trust in their care/services and charge me for late cancelation. I called their other locations which directed me to an answering service. I finally called the WC location again this afternoon and left yet another message to cancel my appointment. Please do your own research for a provider that cares about your health. In the Walnut Creek area there are lots of options.
