Glenn Dental is located in a beautiful, uniquely mirrored building in Apple Valley (with another office in California City). The architecture is beautiful, and the parking lot is large and accommodating. The entrance is accessible with a wide ramp and no stairs for anyone using a cane or wheelchair. Inside, the facility is pristine, almost looking like a high-end luxury spa instead of a dental office. The waiting area features a mixture of seating, including plush, cozy seating as well as unique clear chairs. The receptionist area is wide, and the staff is wonderful, consistently kind, and respectful. Even the bathrooms are unique with modern see-through sinks! During my first visit in September 2025, I was given a tour explaining their equipment sterilization process, and I was shown the different procedure rooms. As someone who deeply values transparency and honesty, this immediately made me feel safe. The hygienist, Cara, was amazing. She was incredibly gentle with a wonderful bedside manner. Her gentleness was not only a compliment to her technique, but it was a sensory relief for me. Over the next few months in late 2025, I returned several times for a crown, a filling, and a few quick, complimentary bite adjustments to resolve some misalignment headaches. The high standard of care was always consistent. I like to understand what's going on with my care, and I felt safe to ask questions about my treatment without ever being made to feel silly. However, my recent experience as a VA patient showed an issue in communication. After receiving automated email reminders in early 2026 stating it was time to schedule my biannual cleaning, I reached out to Glenn Dental to initiate the request. Because the VA Community Care authorization process takes time, I expected a wait. What I didn't expect was the lack of communication during that wait. I called Glenn Dental twice over the course of two months, once on April 6 at 1:43 PM, and again on May 1 at 12:36 PM, and left two separate voicemails to check on the status of my cleaning. Unfortunately, neither of my calls were returned. Ultimately, on June 8, 2026, I chose to stop by the office in person to follow up. Since I had previously contacted Community Care and brought my authorization number with me, I was able to successfully get scheduled. The front desk representative remained professional and apologized for the inconvenience. The explanation provided was that the VA Coordinator handles those specific callbacks. However, I thought a business phone belonged to the entire front office. When I left those messages, anyone could have returned my calls. Whether it was a system glitch, a tech outage, or messages simply getting overlooked during a hectic day, the ball was dropped. I understand that third-party approvals take time and that the office has to wait on the VA. If someone had reached out with a quick, two-minute courtesy call just to say, "Hi Melissa, we received your messages and we're still waiting on the VA paperwork, but we haven't forgotten you," it would have felt like I was seen and not ignored or overlooked. I consider that an extension of my care and dental relationship. I am grateful that Glenn Dental contracts with the VA to serve veterans like me, and I truly hope this communication breakdown was just an isolated blip. Because the clinical care and the staff have otherwise been top-tier, I still recommend this facility, I just hope to see their communication updates improve for patients in the future. read more

After 15 years as a patient, it's very disappointing to see the service decline so drastically. I spent 2 hrs trying to call their office during business hours, no response. This has been constant. I've the last year, it's near impossible to speak to someone on the phone, let alone schedule a timely appointment. Time for a new dentist. read more

Glenn dental is highly recommended because of the staff and the dentists professionalism. The dentists are very skilled and knowledgeable of what they're doing. I got my tooth extracted here and I didn't feel a thing . They have a very gentle hand (dr. Glenn and dr. Lee) . I also do my teeth cleaning here regularly and my hygienist is very good and she also has a very gentle hand. The staffs are kind and friendly and the facility are very clean. read more

This office stands out amongst the 6 other dental offices locally that I've had experience with. Happy, clean, professional, well equipped, well staffed. No one day a week specialties, they take care of business now, not next month. This staff is extra special, you won't believe the difference until you try it. I had a local office drag out treatment for 7 months, then tell me they couldn't get care approved, GLENN DENTAL had approval in 2 weeks, finished the job within 4 weeks. 2 bridges and a crown! Dr. Lee, he's now my brother from another mother! Impeccable work, a perfectionist! Never rushing in and out. I would put this office against any office. Glenn Dental, you are champs! read more

I'm not one to leave reviews but my last and final experience with them made it my last. I've been going here for about 10 years now, my whole family as well and we've watched their communication and treatment of patients decline. My last experience was a root canal that needed 3 separate appointments? and the phone calls in between i was being told different things compared to what i walk into and am told differently once i'm in the chair. I'm sad to have to look for a new dentist after all these years. read more

This dental office is the nicest in the high desert. Dr. Glenn personally designed and decorated it, and you feel like you're in a beautiful museum, rather than a sterile dental office lobby. This is a PPO dentist, so it's a whole different world than the millhouse quantity over quality service you'll get at an HMO dentist. Noticeably after the decor, you'll notice the cleanliness. This office is immaculate clean. As a former dental assistant, having worked for both HMO and PPO dentists, I will tell you that at Glenn Dental, (PPO) you won't get prescribed treatment here if it's not necessary. As they are not an HMO dentist, they do not have to over-treat (quantity) or fear-monger you to get you to agree to treatment that isn't necessary. So you aren't going to be told you need work done, unless you actually do. They do offer Invisalign to almost everyone, but also graciously accept your decision to decline without a lecture. Their treatment rooms are equipped with the latest technology to make dental treatment comfortable and efficient. They use ultrasonic water for their teeth cleaning, so very little manual scraping of the teeth is required and it is a far more thorough cleaning in a much shorter time. Their hygienists are well trained and friendly, who also don't routinely demean or lecture you about how insufficient your flossing is. Each treatment room is semi private so it's not annoyingly loud with noise from drills and treatments happening in other rooms. Each staff member is wearing an earpiece, and they speak to one another quietly through this method, so it's very peaceful. The dentists are all exceptional, highly trained, friendly and approachable, and fit the patient-forward vibe here. Glenn Dental respects individual health choices- I take a holistic approach to my overall health, one of which involves oral oil pulling and being totally fluoride free, and they are respectful of this choice and don't lecture or push fluoride on me. So appreciative! As there are no holistic dentists in the high desert, I would ask Dr. Glenn to consider expanding into those offerings, starting with more fluoride and teflon free options for those who don't want those chemicals in the little toothpaste packets and having an option for floss that isn't coated in Teflon for "easy glide." Now that we know better about these chemicals, we can do better in serving the patients making these intentional health decisions. Each treatment room has a patient TV over each chair, however, using them seems to be discouraged, by having them off and tucked away against the wall, and not offering them, as they once did. Unfortunately, the cell service in the building is limited to one bar for Verizon customers, and they don't offer patient WiFi, which feels a bit out of context with the patient-forward vibe here. WiFi would be a simple, but highly appreciated perk so patients could listen to a podcast or music in their EarPods during treatment. I have been a patient at Glenn dental for over 10 years, and I cannot imagine going anywhere else. I truly love this dental office and now all of my friends and co workers switched to PPO and are patients here too! read more

Been a long time patient of Dr. Glenn. He is an excellent dentist. Staff is friendly and professional. Kevin made me feel comfortable as he did my cleaning. Dr. Glenn is the best in the High Desert. read more

Love this dental office! Staff is professional and friendly and the facility is very clean and state of the art! The best experience I've ever had at the Dentist! read more

Glenn Ong-Veloso I don't know how, with a staff of so many in the Apple Valley office, how they all manage to be so kind and professional every single visit. But they all are. I've been a patient here for many years, but this last year and the dental implant process has turned out better than I'd ever hoped for. Thank you Doctor Glenn, thank you all for taking such good care of me. read more

horrible. Went for a check up in March. Charged my insurance for cleaning, never happened. Only x-rays. Also told me I had 3 cavities. Today I went to another dentist for a 2nd opinion, was told Zero cavities. I'll be contacting my insurance and what ever associations I have to to have them fined. read more

First time using this office, we recently moved to the HD- my husband went in for a regular cleaning. He came out with an invoice for 3K for a regular cleaning. He has no other dental issues. I have PPO Delta Dental and I've never been billed for a regular check up. We declined the services and still ended up paying out of pocket for X-rays! The rest of the bill for X-rays and other items that I don't understand was billed to my insurance. The office is beautiful but is this part of the bill? read more

Had a fantastic experience here the other day. Had a root canal done, which everyone knows is a pain in the butt! It took almost three hours of work! Shoutout to the amazing staff, they made those three hours go by in a breeze. Very nice and funny people. Specifically Dr. Lilly and Dr. Sang made the experience great! No one truly likes going to the dentist...let's be honest...but they made the experience way better than anywhere else! 1000% recommend! read more

I try to patronize the services in my community but so sometimes the business will not permit you to do so. On my last interaction with this dentist I was in excruciating pain they prescribed antibiotics and sent me on my way. The lady at the desk before I left said she needed to one my insurance to determine if I'm covered, I have dual coverage mind you not to mention this tooth is killing me. I permitted her to do her job in the mean time there was no follow up appointment made nor was I contacted to advise what the insurance shared. In the mean I received a bill in the mail for 50 dollars but didn't no what for and called the office manager. He informed me that is was because I didn't cancel my appointment on a Saturday, but I had the person who took my call didn't do their job. Anyway, I finished the antibiotic but was still in pain so I went to a different dental group down the hill. The dentist performed an examination and immediately saw the my the tooth with a crown was infected and that's why I was in so much pain, he sent me to a specialist who scheduled me to be seen in a few days because the swelling had to go down. When she saw me, the removed the crown and determined the the dentist who performed the initial root canal missed a nerve so she treated it and instant relief. Ok fast forward to today. I called this place to schedule my routine cleaning and was told my account is inactive, why is this? You deactivated my account because your staff didn't do their job. Told the lady that's fine, I'll take my business elsewhere. It's so very difficult to get good service in the high desert! So disappointed! read more

My family has gone to Dr. Glenn for many years. His dedication to his patients is seen in the most updated procedures in the world of dentistry. I had a cracked molar that needed attention. I was leaving on vacation the next week. So, at 8:30am I was being fitted with a temporary. At 4:30pm I was walking out the door with my new crown one hour later. Amazing job by everyone involved. Thank you again. Over the years we have needed braces, cleanings, fillings and crowns. Thank you read more

Glenn Dental is the only high end dentist in the High Desert. From the assistants to the hygienists to the man himself, I can't say enough good things about the standard of care, latest technology and customer service. Even when I had an emergency with a broken crown, they dropped everything and saw me right away before an out of country trip. Thanks Glenn Dental! read more

I received oral surgery and dentures from Glenn Dental in March 2024. The oral surgery went well I thought. It was the denture aftercare for fitting from Dr. Glenn and Aspen Dental that is the problem. I complained about the "temporary" cushioning gel I had been given to the office staff. I was called in for an immediate appointment where nothing was done about my so-called temporary "comfort" fitting. Instead of a solution in May 2024, my can was kicked down the road for "permanent comfort fittings" in October; this was five months of waiting for my last appointment. I received a call from Dr. Glenn's office a couple days before this appointment. I told them I had a vehicle problem, and that I would have to reschedule. Instead of a last appointment, Anna at the front desk, would not give me a new appointment. I called to reschedule two days after I had to reschedule my last appointment. So, I was loading my dentures with the crappy "temporary" now "permanent" comfort fittings in my ill-fitting dentures with no where to go. Thanks Dr. Glenn, and Anna, for basically saying, "take your crappy ill-fitting dentures down the road you toothless loser." Way to treat a Disabled Veteran with four cancers (two of them bone cancers)! read more

Dr. Glenn is amazing and the Dental hygienist and Jennifer are WONDERFUL!! But the front staff is VERY RUDE!! Not welcoming they do not know what they are doing! Kept going back in forth with insurance' as much as I liked to see Dr. Glenn I can't with rude staff! read more

Highly do not reccomend for orthodontics. Sure the price might be cheaper. But Dr. Glenn is never there to do treatment month after month. I encountered this for the last 2 years. I had them take off the braces for my child today. Whenever I asked about certain things regarding treatment, I was always given the same answer. "He isn't in". Never mattered what day or time the appointment was. This practice was great at one time, but not anymore. read more

This is in conclusion to my recent review on Glenn Dental. Still feeling the same as my review, I must say they messaged me to help with my Invisalign and while I'm there they would address my other concerns. I have to give them credit for responding. Although I am interested in the Invisalign correction, I'm not sure about the others... read more

Dr Glenn is amazing and the staff are very professional and knowledgeable. The office is clean beautiful and modern!

I'm terrified of dentists in general, since I had a few bad experiences. It took me forever to make an appointment. This place is amazing. The office staff is helpful and nice. The dentists and hygienists are caring and gentle. The dental work is perfect. Hopefully I will never have to go to another dentist again. read more

Highly recommend them! I was scared and anxious to go to the dentist but the staff was really reassuring and patient. I felt completely comfortable and and at ease. read more

I really used to like this dental office, everyone is very friendly, however I just went to get a chipped tooth fixed and had to go back to get it filed down, the dentist appeared very rushed and now my tooth feels a lot thinner than it used to be and it's not straight. I'm very saddened with the results because it is now feeling sensitive and everyone tells me it does not look even. When I brought this to the attention of the dentist he suggested I get braces, which I do want to but my tooth was not shaped like this before. I would not recommend this office. The dentists seem very rushed and I think that's affecting their work. Now I have to go find another office to fix this and potentially take more time off work. read more

Glenn Dental - My tooth looks chipped :( it's not straight - Cosmetic Dentists Near Me - Apple Valley, California

From the moment I stepped into this office I was blown away by the level of professionalism and attentiveness. I booked my first appointment with Dr. Joy for veneers because I wasn't completely satisfied with my smile. Dr. Joy reassured me that it was a very simple, painless procedure and she was right! I was so comfortable and they made me feel like like family. I am absolutely in love with my new smile and I have Dr. Joy to thank! Fast forward: Today I took my special needs daughter in because she's been complaining about her teeth hurting. The last time she seen the dentist (another location) they tried to hold her hands so she wouldn't fight them (we see why that didn't work out). I was enlightened by the kindness that was shown to my daughter. They made a point to show her everything they were going to do and made it fun and exciting, giving her high fives and making her laugh. I will only come to this office and I'm so grateful that they made this experience fun and she's even excited to go back! The best part, she had no cavities! read more

See all

Updating on my "Trudenta treatment" for TMJ/face/sinus/ear pains from decade of clenching/night grinding. 90% headaches/migraines stopped .....if forget to wear orthotic nightguard dull headpain but overall almost NORMAL!!! No more living w/pain. Old amalgam filling broke off while home.....don't have dental insurance but in June my first visit "special cleaning promo" free sign-up to their "INHOUSE Savings Plan($59/yr)" so got that done for $190 half OFF....4 faced composite(!) They don't advertise and I was happy they use composite. No toxic metals. Every 2-3 months Trudenta maintenance visit....FULL treatment w/Nicole, Trudenta specialist + review everything (jaw exercises again) my progress then Dr. Glenn reviews everything (ie: bite CATscan/necessary adjustments/manual adjustment of jaw...). I admit seeing Nicole/getting full treatment is like going to a spa. I feel renewed and she sends me home w/water....flush out toxins released from the treatment! Before I take off Nicole reminds me of exercises/Tens unit for home tx....continued care. If in time I feel the need to realign my teeth I'd consider Invisialign (noticed Glenn Dental is giving $1,500 off the price) but I am doing well for now. I have to say Dr. Glenn different in how he approaches dentistry w/his work, technology and exceptional techs/hygienists plus the workspace is beautiful, peaceful and calming. Thank you Glenn Dental! read more

After my last experience with the office, I found a new dentist and went into the Glenn dental office to pay off my balance. I disputed some charges that my insurance showed me via email and asked the front desk and they just shrugged it off and said that insurance bills aren't accurate and to not mind it. She advised me of my bill at the front desk and I paid it in full... now fast forward 2 months... I'm still receiving bills in the mail because they can't figure out what they're doing. Stay away from this office. read more

I started my contract with Glen dental and they stated that the Invisalign propel device was given to me free of charge. In my contract it showed that they didn't charge me directly for the device, but they included the $650 from the total amount of my Invisalign fees. I didn't even notice this , until I had a front desk employee calculate my amount due , and calculated that I was paying my last payment to later find out at my next appointment she all of a sudden forgot the calculation break down she told me at my prior appointment. I had full confidence that my dentist wasn't going to try to rob me blind and boy was I wrong .I asked the manager, for a copy of my contract and my payment breakdown , he apologized for her miscalculation but informed me because I didn't have Proof we had to go by what they had on file . moving forward I knew I had to keep all my receipts and watch them carefully . After reviewing my contract and throughly showing the manager where they tried to overcharge me $650, he apologized, fixed my contract and took off an extra $200 for the inconvenience. He claimed it was an "honest mistake" which I really wanted to believe so . Moving forward , I wanted a thorough break down of what I paid and what was owed. Tony assured me that wouldn't be a problem, and it wasnt, until my last appointment . On my last appointment anna pulls me into the office again to say ... "I know you've been talking to Tony , but you still owe money for propel device ". I explained to her, again... that my Invisalign package came with that device for free & I didn't owe them anything more than what was discussed In the email and I wanted to speak to the manager Tony. Once I spoke with Tony I explained to him how overwhelmed and taking advantage of I felt. Tony reviews my contract and says I owe money for the device . I told Tony to check his email in case he has forgotten that we already discussed and fixed this issue and all that I owed was in the email he sent me . Tony replied "what email." At this point I was completely disappointed because I really trusted this dental office and what was supposed to be "an honest mistake" certainly is starting to seem like manipulation. Once he saw the email we agreed on the balance due that was stated on the email and he never apologized for them trying to overcharge me TWICE ! He was very rude and unapologetic.I thought getting my braces off would be a happy experience but instead, my experience was the complete opposite. I cannot believe such a nice looking establishment like this would try to rob me blindly not once, but TWICE . Which proves to me that this was NEVER "an honest mistake" . When I first came to Glen dental I fully trusted them, after my experience I would never recommend this dental office unless they get new friendly people at the front desk who actually know how to calculate and understand the balance due, And a new manager that knows how to be a leader and calculate and remember correctly what was calculated . I am so glad that I kept a paper trail because they would've been perfectly fine robbing me blind and no one apologized. I would like to say that doctor Glen is a good dentist and I love the way my teeth look once my braces were off, but the anxiety that came with dealing with the rudest staff member of all Anna , and a manager who isn't a good leader (Tony ) was not worth it . The dental assistants Jen and Ashley were very nice and understanding of how I felt and they did the best they could to make me feel comfortable while they were taking my braces off . I really appreciate those two lady's for helping to re assure me that they would take care of me and get my braces off because at this point I completely forgot about the end goal of being happy with my new smile and having my braces taken off, all I was happy for was that I would never have to come back to this corrupt dental office again! I really hope doctor Glen takes a good look into his staff because they are killing his reputation. My only advice to anyone who is currently a patient here , or thinking about becoming a patient here, is that YOU MUST THOROUGHLY EXAMINE YOUR CONTRACT AND MAKE SURE THE MATH IS RIGHT AND THAT THEY DIDNT SNEAK ANY EXTRA CHARGES IN. I definitely learned a huge lesson from this dental office and I will never come back here . Good luck to current patients and future patients . Hopefully I was the last person they tried to rob blind . read more

My first visit was great, but couldn't tell you about my second visit because I have been trying to schedule something since November and they don't respond to my confirmation texts. They text to schedule appointments and when I reply to confirm (which is in the instructions as an option), they don't respond. After the texts clearly not working, I had called and left a message explaining the situation, and crickets. Surprise, they don't respond to phone calls either! It's going to be a laugh when they finally respond to me in a month again to set up my appointment that they never schedule, when it's already gonna be taken care of by another dentist. They have been giving me the run around for months. Apparently when I spoke to other clients that used to go with them, this is something they always had a problem with. read more

Terrible customer service. Don't bother coming here if you need any type of authorization for dental work. You will never receive a phone call to follow up on things. 3 months will go by and 10 phone calls later, NOBODY calls you back. The High Desert is going to pure crap with lousy help in the offices. I don't think Dr Ong-Velloso does not know what is going on in his office. I would not ever recommend this office to anyone. Look elsewhere. This place is a pure headache and high blood pressure. Seek care elsewhere. read more

Dr. Glenn and his staff are THE best! I am new to Apple Valley and researched comments online. His practice had all positive reviews. And I'm not talking about two or three ... there were about 45 glowing reviews. I went there this Saturday for a consult and he was able to do a filling same appointment. Flawless and excellent work ... truly a cosmetic and caring dentist. He listens to what his patients want. The appointment process was easy to schedule over the phone, as well as filling out my medical history on a touch screen in their reception area. Everyone was so professional and polite. The office was also immaculate and comfortable. You can't ask for anything better in every respect. Thank you Dr. Glenn and entire staff! You made my day, my month. I have found my jewel in the desert. read more

I have had to have a crown replaced several times by this dentist. Doctor Joy has made this mistake. I am left with a open root canal that has been re-infected due to the crown not being causing a uneven bit and TMJ. Ask around town before going here they don't care about their patients just money. read more

So happy to have found this dentist. Dr Joy is wonderful and both she and Dr Glenn go above and beyond with our entire family. My son has one of the most complicated Ortho cases, and Dr Glenn has been so thoughtful and creative in his approach to keep him from having serious problems down the road, as well as losing permanent teeth. His treatment plan saved my son from really having an issue. I wouldn't recommend any other dentist up here for adults. We switched the kids here just because of location, and have not regretted it. The kids miss their old dentist (he was equally awesome!), but having ortho and dentist in the same office, close to our house, makes it easier with how much time we spend here. Our family appreciates this staff and their care and attention! read more

Very expensive! Dental work i was very satisfied with but when it comes to billing you and your insurance, WATCH OUT! They try to sneak things on the invoice to insurance company that you didn't have done. They also use a 3rd party biller and when you try to talk to someone in the office you get the run around. If you like feeling frustrated with invoices, billing and insurance by all means go to Glenn Dental. Oh and if you like the way the ladies treat you (rudely) when asking billing questions. This is the place for you. Don't let the other good reviews fool you, again WATCH OUT for this place!! read more
