I went in for a cleaning and everyone was so kind. Alex took my x-rays and did my cleaning and was really quick and gentle. Lindsey Peaton did my check-up and was so fun to chat with. Dr. Genen… (sorry Doc, i don’t remember your full name) was also caring and listened to what my concerns were and ensured a great visit. VERY HIGH QUALITY DENTISTRY!! Huge thanks to all three

This was the first dentist in a long time that helped fix my teeth and they did a fantastic job! I had a dental emergency and wasn’t even a patient of their’s yet but went to 3 different places with no luck- they squeezed me in and fixed my cavity! I really loved them. Their staff was so kind and caring. My husband had a great experience with them as well.

This practice was night and day from the last dentist I saw, and has restored my faith in the industry. The staff is positive, honest, kind, and experts in their positions. I had just enough time to pour myself complimentary coffee before I was being called back, and with out delay I had X rays, gum checks, and oral examine done and a treatment plan presented. We went over the options, my budget, my needs and wants, and drafted something that worked for me. There was no pressure and no judgement for my financial limitations or neglected dental health. They are professional, warm, and the office is fully equipped with state the art dental equipment. I went in with a general distrust of dental offices based on my last experience, and they restored my confidence in the profession.

I cannot express how much I love and appreciate the wonderful people in this office! My hygienist, Mrs. Kristina Radovic, is AMAZING. She’s so very nice, enthusiastic, and is amazing at what she does. I always walk away smiling until my cheeks hurt! I had my initial Periodontal treatment in October of last year which Kristina preformed for me. Did I mention I never enjoyed going to the dentist? So I was rather anxious and nervous for my appointment. I tell you what though, everyone made me feel so comfortable and confident that I was going to make it through just fine. Kristina was very informative and let me know what she was doing the whole time. I had my second Periodontal Maintenance appointment today and am looking forward to my third! My teeth and gums feel and look wonderful! I am so very happy with my results and would recommend anyone and everyone to this dental office. You will be treated with excellent customer service and honesty, and most of all you will be more than happy with your smile! Thank you all for being awesome! 🙂

We have been going to Gateway Smiles for many years and Dr. G is the best, most honest and gentle dentist we have ever had. Everyone there is always professional and listens and takes care of each of us as our needs are different. They give us options for payments and are very fair! I would suggest anyone to go to this Gateway Smiles and see Dr. G!

I had my first dental exam in about six years this past Wednesday. I knew it was going to be bad since it had been so long, and it was. The staff made me feel so comfortable and really explained to me what was going on with my teeth and gums. I was very nervous, but once Barbra (the office manager) told me my treatment plan and payment options I felt very comforted and informed. They told me I had Periodontal Gum Disease just from years of not having a through cleaning. They scheduled me in the following Friday (only TWO days after my visit!) to come in and have the Periodontal treatment. The treatment was preformed by Kristina who was nothing but AMAZING. She let me know exactly what she was doing at all times during my treatment, and was able to remove ALL of the plaque and tarter from my teeth/gums. The treatment session lasted and hour and a half, and it just flew by. I did not have to be put under, and did not receive “laughing gas”. I was given Oraqix and local anesthetic shots. After my mouth was numbed I didn’t feel a thing. I HIGHLY recommend this facility, and that you ask for Kristina! I will definitely be going back for all of my dental maintenance and procedures. -Tori D.

Unlike most people, I actually enjoy the dentist. So when I come across a good dental office I feel obligated to tell everyone about it! First off, the office staff was very personable and professional. I was really impressed when I went in for an aching tooth and found out I had a cavity elsewhere. Dr. Genenbacher took care of my cavity along with my achy tooth and I was out in no time! I was also very pleased with the ease and comfort of the dental x-rays. For those of you that have had any, you know how uncomfortable they can be. I am very pleased with the service and compassion that Gateway Smiles provides. Their office is very clean and the whole office staff is amazing! I was lucky to meet both Dr. Genenbacher and Dr. Oates and to say the least, I was incredibility impressed! I, as well as the rest of my family will definitely be returning to Gateway Smiles.

Been a patient about four years or so now, and I am a major mouth pain weenie. However, dental health is important and so I go as recommended and never got anything but good care here, and that includes two oral surgery sessions. Even with my insurance dental care is expensive no matter what, but they offer different options to help you out as needed, too.

I was anxious going to the dentist after like 2 years,but going to Gateway Smiles was the best choice.The dentist and dental hygienist gave me all the information I needed in improving my dental health.They were very friendly ,and I felt like all my questions were answered.The dental hygienist there made the cleaning process less painful(only painful due to gingivitis),and calmed my anxiety by making me laugh.Definitely will be back.

Gateway Smiles sets the bar for friendliness, professionalism, and efficiency. Years ago I had some bad experiences with another dental office in town, and it made me very leery of choosing a new dentist. But I’ve been going to Dr. G. at Gateway Smiles now for at least 3 or 4 years, and have always been happy with my experience. From the pre-appointment confirmation calls to the quick and easy check-in process to the x-rays, cleaning, and visit with the dentist to scheduling my next appointment, the staff here makes what could be a chore a real bright spot in my week.

Carolyne S. from Apache Junction, AZ (Source: Yelp)


I’ve been going to Gateway Smiles for more than a year now and have had all the basic dental work I had been putting off for years–including two partial dentures and several crowns. I am very happy with the new technology that makes crowns right in the office via something like a reverse 3-D printer in less than an hour. No more walking around with little tin cans over the root canal site for a week waiting for crowns to be made. Thanks to Cigna Medicare Advantage dental plan, the cost was affordable even to someone on Medicare, and it was possible to spread out even the copays on a financial payment plan. I am greeted by name as I walk into the office and it is never a long wait, and everyone in the office is friendly and helpful. Finally, at age 72, for the first time in my life, all my teeth are in good shape, I no longer have ugly metal cavity repairs showing all over my mouth, I’m in no pain, and I don’t dread going to the dentist any more!

Great experience here! Dr. Genebacher is friendly and efficient and does a good job noticing things and giving feedback on my teeth. No guilt trips, just good recommendations. Staff is experienced and great as well, I almost enjoy going to the dentist!

Alexandra W. from Globe, AZ (Source: Yelp)


Gateway Smiles Dental helped me with a last minute visit to heal a cracked tooth, toothache. I left educated and with a treatment plan and referral appointment to an in office endodontist. I could not be more pleased with my first visit. The young Dentist and his team were humble and explained every detail to include offering a 4 month payment plan for my treatment without me asking for one. Thank you Gateway Dental

After moving we needed to find a new dentist and I read the reviews and chose Gateway Smiles over other local dentists because of their customer feedback on line. I am SO HAPPY to have found the reviews to be exactly my experience. I was treated with care, joy and respect. With cold sensitivity and nerve exposure, I was not looking forward to my cleaning but it was pain-free and the best experience I have had in many years! The prices are great and the professional service was above and beyond. You do not mind paying more for excellence and in this case excellence is even at an affordable price! WE WILL BE BACK AND REFER OUR FRIENDS TO GATEWAY SMILES – without any hesitation!

I have had terrible experiences with dentists in the past and its left me with anxiety ever since. I tried gateway smiles and was blown away at how attentive and personable they were to my needs and concerns. Both the phenomenal hygienist and the doctor made sure I was comfortable and checked in with me  frequently throughout my procedures. I would recommend this dentistry to my friends and family, they’re wonderful.

Gateway Smiles has impressed me again with the efficiency and painless care that they provide so consistently, Dr. Genenbacher and his dental assistant Brandy were absolutely amazing – I strongly recommend Gateway for anyone’s dental needs!

This place I came here randomly after a quick google search and I was so happy they were opened they fit my daughter into their schedule for an emergency apt took xrays of her teeth and we were able to see a dentist unfortunately my daughter has a problem a little to severe and was referred to a pediatric dentist but the fact that they were able to see her and give us some idea to the problem really put our minds at ease as we are cash pay patients we walked out of there free of charge. They were extremely kind as well. My husband and I will be returning to this location to get work done on ourselves. Thank you guys so much I truly appreciated it.

I have waited to write this review so I could “really” be truthful in my opinion! I am one of the worst patients for a dentist – let my teeth get so bad that it took some major work to help me. I have always had that “fear” since I was a child so coming here took me a long time before making that first move. I opted for the implants because I was tired of fighting the soft food diet I have been on for well over 10 years. I had upper dentures for 20 years now, but no bottoms. I knew from others that those type dentures would give you trouble (chewing etc.) for the rest of your life! It was becoming unbearable to eat like a normal person so I decided to bite the bullet and “do it”, finally. My wife was so supportive throughout all the years, accommodating my eating choices instead of hers. After going through all the consultations, surgery to implant on my bottom jaw, healing then fitting, AND that was all completed some months back. I am now a believer – we have gone out to eat at most types of restaurants now, and I really have tested my NEW teeth on most types of food! I cannot express my joy in eating again (and watching my weight). My teeth fit so perfect and snug, I don’t need any gels, pads or anything like it to feel secure in the fit and usability. I feel re-born! Every time we go out now (let alone picking up food for the week) I can now make the choices most people took for granted. I didn’t remember how tasty it all is to the pleasure my wife now sees in my attitude. Lastly, its not just about eating but also self respect one gets when they feel confident in smiling (all the time now), engaging in conversations knowing my teeth stay in place and an overall well being they have given my life. I also want to give a BIG shout out to Veronica for my after care. I was a pain in the butt making sure they fit “just right”, asking for adjustments. “Just a little bit off the side please”. She worked wonders as well and couldn’t be more pleased with the whole experience! What more could you ask for – a modern office and equipment, very well trained dentist’s on new technology and a staff that should be rated number 1 in anybody’s book. Also no pain – my biggest fear! Respectfully, Mike N.

This place is great, very hi-tech and affordable. I am new here because my last dentist suddenly stopped taking my Insurance. The staff is very friendly, and accommodating. The dentist even came out to the waiting room to introduce himself before I got started. The have some new things I have never seen at a dentist office including a panoramic X-ray and a laser tooth cleaner. I have a follow up appointment in January and will post a follow up review

Raeanne C. from Mesa, AZ (Source: Yelp)


I’m a new patient and was running a little late. The front desk staff was very accommodating and attentive and the check in process was super quick and easy. I haven’t been in for a while and my doctor was very nice and made me very comfortable. My hygienist was super sweet and talked to my the whole time to help keep my mind off everything. All in all a way better experience than my first time around I will definitely be back. Thank you to the whole team for making me feel like this doesn’t have to be so scary!

Krishna P. from Mesa, AZ (Source: Yelp)


My first visit here was very pleasant.  I had been using another dentist for 8 years but wanted to find one closer to home.  The check in process was the most convenient & quickest I’ve ever had at a medical office.  Every single staff member introduced themselves, greeted me promptly & was very friendly.  I have anxiety going to the dentist (due to sensitive teeth) & the hygienist took this into consideration & was extra careful during my cleaning.  Very impressed with my first visit and would highly recommend them based upon the care & attention I have received today.

Just moved to AZ over summer, found gateway smiles, and even though I was terrified (who isn’t) I really appreciated the kindness I was shown from the minute I walked in, to the minute I walked out. The girls at the front are so sweet, the dentist was happy to explain my options and made me feel comfortable. the endodontist was a character. I cannot recommend this place enough.
