I visited the website 1 week in advance to get a pre-scheduled dental appointment date which was even confirmed on the phone by a girl named Stephanie. Also, I even complied with all website requirements to fill up online numerous patient forms and voluminous paperworks for about an hour prior to my appointment date. I clearly specified on the paperworks (as well as verify with Stephanie) that my purpose of dentist visit is to get 'cleaning' and check up (me being a new 1st time client/customer). I even showed up a little earlier from my appointment time of 3:30 PM expecting I would receive the 'cleaning' and check up that I requested (in verbal and in writing). My visit was done by 5:30PM (from 3:30PM to 5:30PM about 2 hours) but unluckily I only received plenty of X-ray exams, a lot of photos of my teeth, and of course the good check up from Dr. Manny. I never received the 'cleaning' that I expected on my purpose of visit for 2 hours. I was advised then later to just make another appointment (with the nice lady at the front desk named Priscilla) for the 'cleaning' schedule for next time.

I could not wait to share my visit with my wife during dinner last night. Both the dentist and his assistants were concerned about my nervousness, and explained the process they were working. They took me in at the time of my appointment

Update ao 19 July 2022 **Response to Owner's Comment - NO-ONE REACHED OUT** Moreover, can you believe this place is seeking $100 payment (see attached bill picture) for NOT PROVIDING SERVICE, made me wait for 3 months to schedule an appointment, cancels my 1st appointment and didn't re-schedule, and made me sit in their waiting room for a long time???!!!!! I SHOULD BE THE ONE SEEKING PAYMENTS/COMPENSATIONS for 4 months of WASTED TIME, gas/mileage, loss wages for missing 2 hrs of work, STRESS, and MAKING ME WAIT FOREVER in THEIR WAITING ROOM!!! The receipt doesn't even explain nor tells me the service they did/provided. It just says... pay me $100 cuz we said so!!!! SMH... **************************************** Unfriendly to VA Referred Patient/Retiree!!! Needless to say it took almost 4 months trying to get seen from this place. My 1st appointment was canceled due to Dentist being sick. In a week span, I called their appointment line 4x, disconnected 2x when put on hold by the operator, and requested for Supervisor to call back due to next availability given was in May. Supervisor called back a few days later. I told her about my difficulties of trying to reschedule which she didn't seem to care. Finally, I got scheduled today. I checked in 10-15 min prior to my appointment and signed in. Female clerk (Leo) quickly said out loud "You Don't Have Insurance!" I responded that I was referred by VA new patient and my 1st time being seen. Another female clerk confirmed that they did get the document I filled out and paperwork from VA. I was told to stay seated. Five minutes later, young man walks in, staff were very friendly to him and started talking about whatever. Oh, one staff is supposedly a Leo and the other is trying to save $ so she can buy a house. Therefore, she's on a sandwich budget lunch. Whatever! Then, young man was called for his appointment. 20+ minutes later, I'm still sitting there. I asked the clerk, sandwich budget female, on what's the status of my appointment. She just responded, they're setting up the X-ray. She didn't say anything after that. She then went in the back and heard females just having a good time laughing. So, I left. I DO NOT RECOMMEND THIS PLACE To ANY OF My FELLOW VETERANS! This place is too PROUD! Customer service is AWEFUL! Their DISREGARD to people's time and effort is a DISGRACE! Ya'll Need to EAT A HUMBLE PIE AND LEARN GOOD CUSTOMER SERVICE!!!

I wish that I was able to post my before pictures... This is the best Dental office in California hands down. I commute from LA to this office and every time I'm greeted like family. The owner is awesome and she will come out to speak with you and work with your budget. Trust me on this one. I would like to thank everyone here that has helped me. Look at my smile!!!

I had an appointment at 2pm for filling and a 3pm appointment for root canel. They were both confirmed. When i arrived at 2pm they let me sit there for 45 min. I finally went to the desk and asked what is the problem. They said your appountment is at 3pm. I said no my appointment was for 2:00pm. They told me they did not have a dentist for the 2pm. I was not called or advised. I lost 1 + hrs of work. This is not good customer service. I told them to cancel the other appointment and walked out. What is happening with common sense and customer service theses days.

I can't even begin to explain how unprofessional this establishment is. Lack of communication amongst each other is their biggest downfall. If you have a patient's records USE THEM, UPDATE THEM, NOTE THEM, REFER TO THEM!!! I had to explain things to multiple different people so many different times. Nobody was on the same page and no one knew what I was showing up for or where we left off when I came in for scheduled appointments. Extremely overpriced for the horrible service. Go to Southland Dental!!!! They will definitely take care of you!

Was not going to leave a review until I went to a new dentist and realized the huge difference in quality and service. First, only dental group that has called me day of to cancel not once but twice. Then, I specifically asked if they did dental work on 5 years which they proceeded to agree they did. For the past two check ups, told me my 5 year old was fine until I insisted they look at a brown spot. At this point, now they said they could not service my son. New dentist, not only is taking care of this but found 3 other small cavities due the thorough exam and advance medical equipment. Also made me realize how outdated this office's medical equipment is once I went to a new dentist. Families please avoid

My husband recently went to this dentist office for standard procedures (a deep cleaning, root canal) and was charged far, far beyond what he should have been, given his insurance (which was accepted here). Several hundred dollars more each time, in fact. After these financial discrepancies, he decided to go to another dentist office to finish his root canal crown procedure. The new office was unconfident in the work that this office left him with and fixed it for free, and quoted him a price for the crown at the exact price it should have been with his insurance coverage. After speaking to his insurance carrier about the erroneous charges from this office, they reported that he was being charged over $300 for a "dental rinse" that he never asked for! Truly maddening. He has filed a complaint through his insurance carrier to try to recoup the money that he was unfairly charged. Avoid this office at all costs if you want to make sure you're not getting severely overcharged, or getting left with shoddy dental work.

Love this office, ladies in the front were so nice and helpful with my crazy insurance. The staff was great with my 6 year old and very patient with him. The doctor gave me information about my son in a positive and helpful manner and terms I could understand.

The Front Office staff were very kind and helpful willing to go over prices and contact my primary dentist to make sure everything I needed was covered. My Dentist was very efficient and quick. He did a great job of administering the shots. I am usually quite nervous going in for any procedure and he was sensitive to that. He also explained things to me and answered my questions. Overall, I was very satisfied and appreciated the service I received and will go back if another procedure is needed in the future .
