Had a great experience with Flash Dental and their new ownership. Emily the Hygienist was fantastic. Dr Franzen was great to deal with and did a great job. Happy that Trey Trippet bought the location. Had previous experience with Trey at their Memorial location and he is a great guy. Welcome to the Heights Trey and staff!

Dr. Franzen was great, he made me feel at ease and comfortable, Diana his dental assistant was so sweet and attentive as well as professional. They both made sure I understood everything that was going on and went through my treatment plan thoroughly. The office is beautiful and at a great location. I will be moving my whole family to Flash Dental. Thank you Flash Dental

Everyone here is so kind and knowledgeable! I have never felt so at ease with dental care anywhere else. Huge plus to have them nearby so I could pop in during lunchtime! Thanks to all the staff, I feel like I can Shine again!

I had such an amazing first visit to Flash Dental! Everyone was extremely helpful, honest, and thorough when it came to a treatment plan for my teeth. I went in for a second visit shortly after my first and I felt as if I’ve known the whole staff for years. Impeccable customer service and extremely clean facility. I will be recommending them to everyone I know.

Dr. Franzen and Gina were awesome! The whole experience from start to finish was incredible. It was very warm and welcoming environment. The whole process was explained to me thoroughly without unnecessary added services recommended, as I have experience with other dental offices. Could not have asked for better. This is my new dental office and I highly recommend everyone go here.

Great experience at Flash Dental! Arrived at set appointment time, walked in, and they started my cleaning immediately. No waiting room time. Modern fixtures and office environment with nice music playing. Tools & technology for the x-rays and cleaning were top notch. Friendly staff enabled a very low stress experience. Highly recommend trying them out!

Great experience! Professional and welcoming staff, modern and clean facility, great dental work. I particularly like the business model: they’ll advise you on what you need to get done but with no financial incentive for them to get you to do more dental work than needed; this sets them apart from traditional dentistry IMHO.

The team was so helpful at Flash. I met with Emily who was extremely knowledgeable and was willing to share the process of how things work along with what I was to expect during my appointment and even after! The dentist office is already supposed to be an uncomfortable place but they made it feel inviting.

Saying Flash dental is superb is an understatement. The staff is so friendly. Dr. Franzen is super knowledgeable and thorough. Emily cleaned my teeth and was so kind and made the cleaning feel like a breeze. Gina at the front desk was so helpful and made sure I was taken care of. Diana, the dental assistant took my X-rays and made me feel so comfortable. Usually xrays are uncomfortable for me and she made it so easy. The office is so modern and clean, not to mention they have topo chico! Highly recommend Flash!!

I recently visited flash Dental for a cleaning and had a crown done as well. The staff is very friendly and prompt. I usually hate going to the dentist but they made me feel very comfortable. Gina, Carolina and the Flash Dental crew superseded my expectations! Highly recommend checking it out.

10/10 recommend Flash Dental – my appointment was quick and easy! Everyone was so friendly. Gina, at the front desk, was super helpful and so sweet! I loved how modern, updated, and beautiful the office was too. I initially just went in for a nightguard appointment, but I can’t wait to go back for my cleaning!! (Never thought I’d be excited to go to the dentist.. lol.) Go to Flash! You won’t be disappointed.

I have always had anxiety going to the dentist, but I have to say the team at Flash Dental made me feel relaxed and well taken care of. Dr. Franzen and Diana did a great job on my procedure and made sure I felt comfortable the whole way through. Gina, at the front desk made the check-in and check-out process a breeze. Highly recommend this office for your dental needs!

Normally don’t do reviews for non-restaurants but I had an awesome experience here. And I thought I needed to share it with others. The staff was truly welcoming. Friendly staff. Good communication: Opened to share good places to eat around Houston area, especially the Heights. Offered me sparkling water, which I loved! Ambiance was nice. New and modern. Open layout with a lot of natural lighting. Had a great dental experience. Definitely coming back.

What an awesome experience and I LOVE my white teeth. A little back story…had Zoom 10 years ago and couldn’t finish (35 minutes) because of the pain so my teeth only got about 3 shades whiter. Leslie (who is so nice and informative) told me that Zoom had improved over the years and it’s almost painless. SHE WAS RIGHT! After a full hour under the Zoom light my teeth look amazing. I am beyond thrilled and the results surpassed my expectations. There was also another ZOOM patient there when I checked in and she had the same experience. She couldn’t stop smiling. Her teeth looked equally great. So white and clean. A very clean, professional and FUN environment. I am so glad I found Flash Dental and plan on going back. They know teeth!!

Staff is all very friendly and knowledgeable. From the front desk to the hygienist to the dentist. The office is very nice with all the latest technology. It was very easy to get an appointment and I was seen immediately. I was in and out very quickly and my teeth feel very clean and much whiter than I expected. Thank you!

I had an excellent experience at Flash dental. Dr. Franzen did a very thorough examination and recommended a cleaning. Dr. Franzen and his assistant Diana made the process quick and felt no discomfort whatsoever. I will be referring friends and family to this location for any dental work, thank you.

I have always been incredibly afraid of the dentist, until now. The staff, my dentist, everyone at Flash has been nothing less than superb. They all have been very informative on my procedures and what my treatment plan will be. They all have done everything they can to make me feel comfortable during visits. Their prices are great. The office is very beautiful. I have already recommended them to three family members of my own. All in all if you are looking for a new dental experience, look no further, Flash Dental is absolutely the best place to experience nothing but positive, when visiting a dental office.

I love the flashy, sassy atmosphere; the people are warm, friendly and attentive. Great dentists too who actually take the time to meet and connect with their patients. I did not feel like a number at all, like I do at other dental offices. Thanks for a wonderful experience! I will be back…And I absolutely loved walking out the door with much brighter and whiter teeth too! Thank you!!!

I had a great experience at Flash Dental and will definitely be going back again! I usually hate going to the dentist like most people but at Flash Dental it does not even feel like a dentist. No traditional dentist office smell and it does not even look like a dentist office when you first walk in. On top of this the staff is super welcoming and friendly! I am new to the area and I was very happy when i found a good dentist like this first try.

The overall atmosphere at Flash Dental is so casual yet very trendy. Everyone who works there is very professional and made me feel very comfortable. I first met the team at the Heights Crawfish Festival, and they definitely stood out to me as a “different” kind of dental group. I highly suggest trying them out!

I had an excellent experience at Flash dental. I believe its under new management and staff. Everyone was courteous, the ambiance is quaint and relaxing. My cleaning was quick and thorough, my higegenist explained everything she was doing, which I really liked. I was very impressed with the Dentist. He also did a very thorough examination. I also had zoom whitening, and although the process can be long, I felt very comfortable and even dozed off for a bit.

Had my dental check-up done this past Thursday. Great first impression and energy from the staff when I first stepped in. Had a what i felt to be a really good and thorough cleaning. Also the Dentist followed up after the Dental Hygienist to make the check up complete. Would recommend to anyone looking for a new dental home office. In addition to the cleaning and dental check-up, i also had the Zoom whitening treatment which i was very happy and satisfied with.

What a great experience, especially during the complicated COVID era. The process to check in was simple. I was immediately taken back for X-rays and then cleaning. My hygienist Gina was wonderful! Got a great cleaning and then a great explanation by Greg on what next steps I should take. While it had been a while since my last cleaning, there was no upswell on things that weren’t necessary. Happy to have found this practice!
