Found Lowry Advanced Dentistry through a mail advertisement. Came in, and their check in was so professional and polite. Check in was done on an iPad, quickly. Then the hygienist was so pleasant! By far one of the best bed-sode manners I have ever had. She explained everything in detail that wad understandable for me. I was not shamed for my lack of flossing. X-rays were quick and easy, with a handheld xray gun! Very positive experience, I will absolutely make them my regular stop for cleanings and such!

My brother recommended this place, as my old dentist closed shop and moved along. My dental hygienist Kristy took her time to explain things and most importantly took her time while cleaning to avoid discomfort. I didn't feel like the appointment was rushed at all, contrary to other experiences at other dental offices. In a business, it's understandable that quantity matters, yet striking the right balance between that and quality was clearly evident here.

She really made my experience extraordinary. The DMD, Leif Gambee was also personable, knowledgeable, and delivered great service. If you're looking for a dentist, you need look no further.

We are so happy we found Dr. Gambee and his team. My husband struggled over the years with an implant and this is the first time he has seen progress and he is feeling confortable with his dental work. He spoke so highly about his new experience that we decided to move as a family to Dr. Gambee's practice. From the moment we stepped into the office, being greeted warmly by Kirt, to the friendly and caring dental hygienists Kristi and Michelle, to Dr. Gambee's compassionate approach, we could not be more pleased with Lowry Advanced Dentistry.

Great staff, great experience, up-front with all procedures and prices. Highly recommended! Edit: Can't stress enough how great Dr. Gambee and the entire team are. If your current dentist is "just a dentist, " (or you don't have one) LAD is worth going out of your way for. They made it extremely easy and painless for me to switch over and get current on everything.

The atmosphere is just fun and it makes going to the dentist fun. Dr. Gambee is so helpful and generous with time and resources, he and the rest of the staff really take the time to make sure I'm comfortable and happy with the way things are going. This will be my home office as long as I'm in the Denver Metro area, and potentially beyond that.

I had an emergency tooth extraction within an hour of calling. The doctor and staff are the best. Treated my discomfort and medical issue in a professional, kind, and caring manner. If I lived in Denver, this would most definitely be my dental service provider.

Dr. Gambee fixed my front teeth by multiple adjustments, and calls back and forth with the lab. It was a challenge because I have a 20+ year old implant. I call him "Michelangelo", because he made my new teeth look like they belonged in my smile. And they look 10X better than the last time work was done. Thanks Dr. Gambee and Team at Lowry Advanced Dentistry. Appreciate it very much!

I'm always tentative when going to a new dentist because I have had so many bad experiences, however, this was the best dentist experience I have ever had. First, they took my insurance info when I scheduled the appointment so it helped alleviate some of the work I had to do when checking in as a new patient. Second, the entire staff was extremely warm and welcoming. Third, the hygienist, Kristi didn't rush the job and was very thorough.

It was the first time in my life where I had my teeth cleaned and didn't feel any pain. Fourth, Dr. Gambee was very nice and professional and didn't make me feel any type of anxiety that typically comes with going to the dentist. Would HIGHLY recommend if you are looking for a new dentist.

Amazing experience with Dr. Gambee and his staff! Thanks to Dr. Gambee, I feel so much better about going to the dentist. I had a root canal done and it was virtually painless. I feel it's because he takes great pride in his workmanship and truly cares about his patients! Dr. Gambee clearly explained everything he was going to do before and during the procedure. I highly recommend Dr. Gambee! Oh, and by the way, I loved the music that was playing during the procedure! It, too, made me feel relaxed!

Great service; very professional; office staff are super nice, the technician is knowledgeable, offers good feedback and has a great chairside manner. The doctor is very nice, has an even better chairside manner, and is far more knowledgeable. He clearly wants my teeth to last and serve me well. The office does not upsell, though they do suggest inexpensive services ($25) to further my dental health.

Excellent, attentive care from the ENTIRE team. I am on a mission to a healthier smile, and in between jobs so insurance isn't an option considering waiting periods. They gave me a proper evaluation with a roadmap of things to tackle, and didn't even hesitate when asked. I get extremely nervous at the dentists and within 10 mins of arriving I felt. relieved.

I left feeling informed and in control of my health. I would recommend this practice to anyone, especially anyone feeling dreadful about going to the dentists. Being in between jobs I also signed up for their discount plan, which is fantastic for savings during routine maintenance and reduced my initial visit and evaluation to $50. I don't even live that close, but I'm not going anywhere else!

I've been going to Lowry Advanced Dentistry for over 30 years! Yes, I stepped away a time or two trying to find a dentist closer to my home, but I always returned to Lowry. I x CCD ant ay enough great things about the staff there. Thank you for making my dental visits do comfortable.

I normally don't write reviews however after the exceptional experience I felt I had with Dr. Gambee and his staff I felt compelled to let others know. I came in with two teeth that severely needed help, Dr. Gambee not only fixed the issue with zero complications but he also worked out a financial plan that fit my budget. My visit was literally the most pain free and wonderful experience! This is a dr who really cares about his patients and I am very appreciative of the care and service that I received

Dr. B and his staff are friendly, knowledgeable and they take your fears and concerns seriously and actually listen! I am SO glad I decided to start going here. I have major dental issues and they have helped me find the best route for me without pressuring me into procedures I didnt need or couldn't afford or didn't feel comfortable with. I am almost done fixing my mouth and it looks amazing. I highly recommend them for all of your dental needs. 5 stars for sure!

I visited Lowry Advanced Dentistry for a second opinion. Their price & plan to fix my smile was less than half of the cost and work of my previous dentist. They are professional, listened to what I wanted and found a way to accomplish what I was asking for without major dental work. The best part is all the work should be completed in 5 weeks instead of 6 months with relatively little to no pain!

Doctor Tom is truly the NICEST HUMAN I have ever met in my life. The receptionists are awesome, his nice daughter Christine works there as well. I was truly humbled by the kindness of the dental assistants. One visit here put me in a good mood for the rest of the week! He is very honest and will tell you if you need something or not. I am going to leave my other dentist because they actually have better prices on just about everything, even the cosmetic part. Thanks so much for being so kind to me and helping me! You guys truly went well above and beyond what you should have, and are a blessing to have here in this state!

Dr. Tom is wonderful. I had extremely painful mouth canker sore to the point I could not concentrate, work or sleep. I consulted 3 dentist for help 2 of which told me there is nothing I can do. Dr. Tom not only had an instant cure for me but he met me there on a Saturday before my trip to Africa to help me out. I am so thankful it would had been the worst 24 hour flight I could possibly imagine. The cure was painful but absolutely worth it. Highly recommend Tom and his team!

A great place and even better service. As much as we all dread going to the dentist Dr. Thomas Bonbright and all his staff worked hard to make sure I was comfortable, understanding of my dental needs and all the options I had. Although they may not be the most inexpensive dental office they certainly are one of the better ones, the work they do is beyond amazing and I do recommend them to anyone wanting the best dental work around.

I have been coming here for years. The staff is so attentive. I had an ultrasonic cleaning and a fluoride treatment done. Morgan, the hygienist explained everything she was doing and was very professional and efficient. She called Dr. Bonbright in for a question and quick consultation. It was an overall great experience - I would not hesitate to recommend this dental practice

Save yourself from this mess of a business! There are plenty of great dental options in Denver, this isn't one. In this case, do judge a book by it's cover. The receptionist, Leslee, makes a BAD first (and second) impression. She's got a sassy attitude and is, no doubt, costing this practice new business. You've been warned! They don't care.go elsewhere.

I just had a ultrasonic gum cleaning done this week at this location. I was treated well by the entire staff. The Receptionist Leslee took care of all my insurance needs and told me what was covered and what was not. Amy did my initial exam and brought in Dr. Bonbright to check everything out. Morgan the Dental Hygienist was awesome with the shots and the cleaning.

This office also deals with sleep apnea which I have issues with and was able to send me home with a device to monitor my sleep. My experience here was great and the prices fair. I was treated for my issues and not over charged or sold anything I didn't need.

Do yourself a favor and get a second opinion before you commit to spending money here. After consulting with another dentist, I found out that Lowry Advanced Dentistry subjected both my wife and I to unnecessary 4-hour deep cleaning sessions to the tune of nearly $1200 each, which was even more painful given we don't have dental coverage. Come to find out, it's generally not standard practice to do such an invasive cleaning all at once, or even at all for patients who don't have advanced periodontal disease (neither of us do). Moreover, I had TMJ symptoms for nearly three weeks after this marathon procedure, and my wife was ill for 2 to 3 days after hers (probable bacterial infection), which was only cleared up after taking antibiotics.

On top of it all, Lowry charges substantially more for their procedures than some other perfectly competent dental practices (for crowns, 50% more). We will certainly never use them again, and you should most definitely shop around before having them do any dental work for you. Be warned.
