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

Literally the nicest humans in the world!! They made my wisdom tooth removal the best experience…read moreand made me feel so comfortable! So blessed to have had them take care of me !!!

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!

I've been coming here in Lake Forest for a while now, both for routine cleanings and a cavity…read morefilling, and it's consistently been a smooth experience every time. 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've been seeing Dr. Roy Kim, DDS since 2018, and he's an exceptional dentist. He knows his stuff,…read moreis kind and attentive, and genuinely cares about his patients. His staff is always friendly and professional. Even after moving from Lake Forest to Tustin, I still make the 25-minute drive because he's that good. I highly recommend Dr. Kim and his team! AAA+

The care is absolutely exceptional from start to finish, and most importantly, you can truly trust the team. I highly recommend Harmony Dentistry to my family, friends, and anyone looking for a dental office they can feel comfortable and confident in!

My family has been going to Harmony Dentistry for over seven years, and I can honestly say it's the…read morefirst dental office we've ever truly loved. 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!
