    Fake endodontist -- he started a root canal and didn't finish it because it was "difficult". Is good at treating cavities.

    This makes me sad to write such a low review since I've been coming to this dentist for years and…read moreyears -- at least 15 years to be honest. My parents have been patients here for around 30 years as well and we've all had such great service with them. I have dental insurance through my company I work for (a DMO), but Dr Lombardi's office doesn't take it. Since I've always been pleased with them, I still go to them for cleanings and X Rays and pay cash. My last visit (two weeks ago), I had X Rays and a cleaning done. I found out that I had a cavity in one of my molars. Since I don't have the extra $500-600 to dish over for a filling, I found a dentist who takes my insurance to fill it (which I had done last weekend -- only costing me $56 out of pocket instead of hundreds). When the front office staff at Dr Lombardi's office found out I was going to another office to get the filling done, they were very rude to me. They informed me that if I go to another dentist to get a filling done, that I'm no longer their patient and I can't come back to their office. I didn't think it was a big deal and I was still planning on going to go to them for my cleanings every 6 months. This morning I received a phone call from Dr Lombardi's front office informing me that they are going to cancel my January cleaning appointment and that I'm no longer a patient of theirs. Say what?! I've been a loyal, cash paying customer for the last 15 years and you treat me like this just because I don't have the money to pay out of pocket for a filling? I worked in a doctor's office for YEARS, I know for a fact that they usually welcome cash patients since they are usually so much easier to deal with than the insurance company. All in all, I'm very disappointed. I lost a great dental office today over nothing. To be honest, my feelings are kind of hurt, but I'll get over it. Beware!

Wait time is minimal, the staff is streamlined and reliable, and appointments are well structured so you're not sitting around wondering when you'll actually be seen. Dr. Kim is great to deal with. He's sociable and easy to talk to, but also genuinely good at explaining what's going on and why, without turning it into a sales pitch for procedures you don't need. No upselling, no pushing expensive stuff you didn't ask for. He also has a very confident, capable hand, the anesthesia administration was barely noticeable, minimal pain, and the office itself is spotless. As a doctor myself, I wish my own practice ran as cleanly and efficiently as his does. When my kid starts growing teeth I will definitely bring him here.

    I usually don't write reviews specially negative ones…read more Review for Dr. Vaughan office Great surgeon, but front office chaos and dishonest price hike are a major safety concern Dr. Vaughan himself was a great doctor, and the surgery went very well for my daughter. However, the front office and billing departments are an absolute nightmare, and I cannot recommend this practice because of them. The front office provided zero details before or after the surgery. Incredibly, they weren't even aware of what medication my daughter was taking, which is a major safety risk. Furthermore, they didn't have me sign most of the paperwork until they were literally wheeling my daughter into the surgery room. They made me stand right in front of a screen to read and sign pages and pages of documents at the very last minute. When I told the staff this shouldn't be happening and should have been handled in advance, it didn't change anything. To make matters worse, the quote they gave me back in February was completely dishonest. I was quoted $300 out of pocket, but they later changed it to $400. Every single time I requested an explanation, the stories kept changing. I dealt with two people, Kim and Clarissa, and the story changed four different times between them. Clarissa first claimed the $300 was "per tooth," which made no sense because I specifically asked for the total cost. Then later day Kim claimed the price had always been $400 for DRF, only to later into 1 1/2 later I requested to look into it and she change her story again and say the price just went up. So which was it? To top it off, Kim sent me an email two weeks after the surgery explicitly stating they were not going to honor the first quoted offer. For me, it is the principle of honesty and integrity that matters, but those qualities are completely missing from this office. I did aware that why I asked for what will be my total cost out of my pocket. If you decide to come here just make sure you have it written down prior and on the day off. $100 extra cost is no big deal. Just be aware. I told them while I was signing, that hope I didn't sign my life away since I was not clear minded after my daughter is wheeling in the surgery and here I have to standing here reading pages and pages for your paperworks, which you shouldn't have given to me the mins during my daughter in the surgery room. Regardless I like Dr. Vaughan if wasn't because if this changing billing stories. Will I be referring family or friends for wisdom teeth done? Not so sure due to the front staffs. The surgery went well and so I am happy for my daughter. Still not fully 2 weeks into her recovery yet. Cross fingers that she doesn't have to return for anything else. Thx you Dr. Vaughan! Front desk team need more guidance in my opinion!

From the moment we walk in, the entire team makes us feel comfortable and cared for like we're family. The office is clean, modern, and welcoming, and the staff is always friendly and professional. The hygienists are incredibly gentle, thorough, and take the time to explain everything clearly whether it's a routine cleaning or a more involved procedure. Linda was my daughter's hygienist until my daughter moved away, now Linda is my hygienist. My former hygienist was Toni until Toni moved away. I can't even say who I like better because they were friends and so much a like! Linda remembers everything we've ever talked about so it's like going in to visit with a friend. Dr Ash and Dr Truong are both so great and also care for us like we are family when we visit. One of my sons got braces this year and Harmony Dentistry works very closely with his orthodontist. This week, my son had a filling fixed, and Harmony was able to call the orthodontist to pop in very quickly to remove one of his bands so the filling could be replaced. How convenient for all of us! Some fun amenities include cold water bottles in the waiting room, Netflix to watch on the ceiling televisions with headphones, and a paraffin wax treatment for your hands if you like! We've recommended Harmony Dentistry to many friends over the years and will continue to do so. It's rare to find a dental practice that combines skill, kindness, and consistency the way they do. We're so grateful to have found them!
