Check out what some of our happy patients are saying about us:

Matt K. from Tampa, FL (Source: Yelp)


I am probably a unique patient in that I can compare the LANAP surgery to traditional scalpel “peel and scrape” surgery as I like to call it. This is needed when gingivitis gets below the gumline and can not be reached with less invasive cleaning methods 3 years ago, I had the scalpel surgery and was not informed I would need to come every 3 months for a regular cleaning to keep gingivitis at bay. Thus I find myself in need of getting the same surgery all over again. This time I went with the LANAP surgery. Here is what I experienced with peel and scrape: Post-Surgery cotton packing Several days of spitting blood out High level of post-surgery pain and inflammation for days afterward Moderate level of post-surgery pain and inflammation for weeks after that High level of sensitivity to cold and heat for months afterward Here is what I have had so far with LANAP: No packing No blood Mild to Moderate pain and inflammation first few days afterward Mild soreness the next few days No sensitivity to cold or heat afterward. The decision wasn’t whether or not to have the procedure done again. I like having my teeth and want to keep them. The choice came down to scalpel again or LANAP. Without a doubt, I am glad I went the LANAP route. The price differential between scalpel and LANAP ( I have no dental insurance so it may be better for others) comes out to a little over $1,000. That slight difference is money very well spent. I would advise anyone getting Perio surgery done not to even consider the scalpel as an option. As for Dr Diez’ office over others, I would recommend they see him. I went for a consult to a Dr that advertises laser in the TBT. Their entire process made me feel like I was working with a used car lot and the stereotypical sleazy sales tactics. I felt like I needed a shower after talking to them. I had even scheduled an appointment with them to have the laser surgery done. After another conversation with them went sideways I decided to look for another Doctor. The next morning I was in for a consult with Dr Diez. The week after that I was getting the right side of my mouth treated with LANAP. Later that night, his wife called me to see how I was doing post-surgery. Twice more after that during the following week his staff called me to make sure I did not have any problems or complications. 1 week after the first surgery, I had the left side done and had a similar experience. Staff and Dr are very friendly and make you feel at ease. I did not have a regular dentist but I will be going to him regularly now.

If you are looking for implant work, periodontal work or just a normal cleaning, you got to go see Dr. Randall Diez and his office staff. I just received my tooth implant (lower left quad) and it feels amazing. No numbing agent was required because Dr. Diez gave me a step by step documents on how to get the best results. the offices staff is very friendly and knowledgeable in what they do. Tampa is very lucky to have him practice in the Gunn Highway area.

I am a dentist from the Central Florida area with over 25 years of experience. I needed a full mouth reconstruction (I was not born a dentist!) and Dr. Diez was the man for the plan! My case was complicated, but seemed routine for Dr. Diez. He has a wonderful staff, a clean, modern office with high-tech equipment and up to the minute techniques. Thank you for my great smile! My patients compliment my smile every day. Dr. Diez is the dentists dentist! 5 stars

I went to Dr. Randall Diez to have two crowns put in. One of the reasons I was so impressed with his service is that he uses state of the art equipment. With this equipment he was able to make the crowns right there in his office. This way you don’t have to use up a lot of your own valuable time going back and forth to the Dentist office until the work is finally done. I was very satisfied with how professional the work was and yet quick and easy. They have a very nice clean office with a very professional and friendly staff. I would highly recommend Dr. Diez to anyone who needs general or cosmetic dental work.

If you are even “slightly” considering a new dentist, do yourself a favor and set up an initial appointment at General & Cosmetic Dentistry of Tampa. I’m a current patient at their Gunn Highway location and have consistently received outstanding care from the entire staff. I have received outstanding care from both Dr Randall Diaz and his son Dr. Michael Diaz over the last ~7 years. They have the latest equipment, a friendly well trained staff and a solid team of experienced dental hygienists. They also host an amazing year end holiday party each year as a way to thank their current patients! Highly recommend!

What a fantastic experience. Everyone was so friendly and a pleasure to speak with. Very professional on every level. I had never been there. They were able to get me immediately. Every thing was explained in detail and there was absolutely no discomfort or pain durning the procedure. I also received a follow call in the evening to see everything is going well. Dr Diez, to you and your team Thanks so much you all are Awesome!

I started coming to see Dr. Diez because my husband has been a long time patient. I do not regret my decision to switch dentists. Both Dr. Diez (Randall and Michael) are incredible. I feel that they genuinely care about my dental health. I absolutely love my dental hygienist Melanie and look forward to my teeth cleanings. Thank you for the wonderful experience every time I come!

Angel Robles (Source: Google)


I’ve been going to GCD for about a year and some change now and honestly I’m pretty mad I hadn’t made the switch sooner. This practice is very warm, welcoming, and has a strong sense of professionalism and family. So far I’ve had two procedures done at this facility and it was well worth everything. One being total wisdom teeth removal and the other being a root canal+crown with a separate filling. Dr. Randall Diez was very meticulous, swift and best of all gentle. I didn’t feel a thing during or EVEN AFTER the procedure. To feel nothing after a root canal is incredible. No headache, no discomfort, nada. The crown was even made IN HOUSE in all of about 30 minutes and needed no adjustment. It was perfect. Clearly the staff at this establishment are forged professionals and most importantly human beings who give 100% of their time, dedication, and expertise to their patrons. If you need to know something, they’ll tell you; if you want to know something, they’ll tell you. The fleet is very transparent and hides zero information from it’s customers. If you’re looking for real dentistry, then stop scrolling and click on this place ’cause these guys are the real deal. Stop trusting a hack with a photo shopped degree with your teeth, and make the upgrade to the golden standard of Dentistry. You deserve it.

My family and I have been seeing Dr. Diez for years, and we are delighted with the high quality of care and professionalism they show us. I also appreciate how much everyone there cares about us as people, not just as a source of revenue. Going to the dentist isn’t supposed to be fun, but the kind folks at G&CDT make it a pretty good time!

Lynn Roberts (Source: Google)


I have a fear of dentists and have for as long as I can remember. I have been referred to practices that have been a nightmare. I am proud to recommend this practice. I have been treated with great care and respect. Dr. Diez is honest and forthright. My smile has never looked better I highly recommend Dr. Randall Diez and his team.

Jamie Massey (Source: Google)


I have been going to Dr Diez since I was 9 years old and I am now 34! He is the BEST!!! I actually enjoy going to the dentist and no one ever says that! His office staff and dental hygienists are top notch and just so sweet and nice! I would HIGHLY recommend him and his office to ANYONE that is looking for a dentist in the Tampa area. Thank you Dr Diez for everything, you really are amazing!

Love this office! Never a fan of the dentist in the past and anyways dreaded any visits. Since I’ve started a a patient at this office, I’ve been nothing but pleased. The whole staff is very professional, welcoming and friendly. I look forward to seeing their bright and happy faces(covered by masks now of course). The transition from my previous dentist to here was much smoother than anticipated, and a much welcomed change for the better. I’ve dealt personal with Julie, Melanie, and Dr. Diez. Every encounter is like freaking with friends and family members. I no longer cringe at the idea of a dentist visit, and look forward to another friendly gathering for the betterment of my health. If you’re dissatisfied with your current dental office, do yourself a favor and give Dr. Diez’s practice a shot.

I’ve been a patient of Dr Diaz for about 20 years. He truly has your best interest at heart. He’ll provide the best options for you and complete them using the best products. The office staff is very professional, efficient and friendly. Like a family. I highly recommend General & Cosmetic Dentistry of Tampa for all your dental needs

Joshua Robinson (Source: Google)


i highly recommend Dr.Diez to anyone in need of an exceptional dentist. He is extremely thorough, professional, yet very easy to communicate.I had a crown that was done the same day which was good so i didnt have to take another day off of work. He personally called me to check on me. I have since returned for follow up visits and I can not express how gentle and how much of a perfectionist he is from a major procedure to routine visits. His office staff and dental assistants are so friendly, caring and accommodating. My family and I will never go anywhere else for our dental care.

Cristina Pantella (Source: Google)


I cannot say enough about the staff and Dr.Diez. Also,Melanie fixed my bonding on my front tooth so I don’t look like I’m buck tooth McBucky! I am so happy that I change dentist.I feel better about myself. they’ve helped me feel more confident with my smile, I haven’t been for the past 10 years and all it took was for Melanie to smooth out that bonding!!! I love the Dentist,again!!! Thank you for more confidence!the positivity of the staff is outstanding! Go girls! Dr. Diez yo have a wonderful staff!!! Ty ty ty cristina pantella

Dr Diez is by far the best, most patient and experienced dentist I have ever been to. I generally loath the dentist but Dr Diez is magical at dissipating that sweaty palm, heart racing anxiety that often accompanies me for the visit. I would make one recommendation in that you get the quote in writing for work that needs to be done. Seems like every time I have work done the quote is lower than the actual bill and and I am always surprised at check out. I have been a long time patient and would be happy to pay the set amt if I am told up front. I do not like a 300+ delta in what is quoted and what is actually charged. The Dr is AMAZING.

Jennifer Sells (Source: Google)


I’ve been a patient of Dr. Diez for 3+ years now and he is by far the best dentist I’ve ever seen. He is very knowledgeable, thorough and takes the time to explain every thing in detail. He is honest as to what needs to be addressed immediately and what can wait. Dr. Diez’s staff is just as wonderful. They are warm, friendly, kind and know you by name. Pam goes out of her way to address any concerns with your insurance as well. I highly recommend Dr. Diez and his staff for any of your dental needs!

There are Dentists & then there are BETTER Dentists.. I broke a filling & had to get some emergency work done. I had a hard time getting an appointment with anyone for emergency repair. I finally get an appointment and I go to a dentist and he tells me that he’s just going to do an evaluation and set up an appointment for someone else to do the repair! I asked him why not do the repair now because it hurts? He said that he couldn’t do it! So I just wasted 2 hours driving an extra 40 miles to get to someone that I can get an appointment with but couldn’t do anything! I was very upset! I left that office and went straight to Randall Diez. With no appointment I explained the situation to them and to my surprise they accepted me in because they knew I was hurting. I walked in so angry and I left so happy! I cannot say enough about these people , they went out of their way to help me get it taken care of. Now here’s the real kicker! I had to have a crown done, where else can you go that is capable of doing the entire job including making the new crown in one appointment! They have the equipment necessary to get this job done in one appointment instead of making someone wait to have the new crown made somewhere else. Not to mention this is a second generation dentist working here. These people have the best bedside manner of any dentist office I’ve ever been in. I hate the dentist because it always means pain for me and they took the time to take care of me properly and I cannot say thank you enough! Job well done guys!

I will not go anywhere else for my dental health needs. I have been a patient of Dr. Diez since the early to mid 90’s. I had very serious gum disease and Dr. Diez along with my periodontist were able to do gum surgery and literally build bridges to save my teeth. IT WORKED! As it stands, I am at 23 years post surgery/treatment and they are still holding strong. After my initial diagnosis, I sought 2nd opinions at 2 different practices and both of them said they could not even accomplish what Dr. Diez did. They said I would need dentures and partials. They were wrong! I cannot stress enough the quality of work that was done. Thank you, thank you, thank you.

Alice O. from Hernando, FL (Source: Yelp)


I have been coming to Dr. Diez for over 20 years. I drive from Hernando Florida and he is worth the drive! He did a bridge for me today and I am so grateful for him and the girls in his office. Everyone is kind and very professional. As long as I can make the drive to Tampa, he will be my dentist. Thank you Dr. Diez

Emry S. from Tampa, FL (Source: Yelp)


I’ve been going to Dr. Diez and the crew for the last 3 years and they are wonderful. Dr. Diez is straightforward and kind and does not try to upsell or overcharge you for unnecessary services like most other dental practices. He is very knowledgeable. Apparently your mouth and teeth and tongue can tell a lot. Dr. Diez was able to see signs of a sleeping disorder by looking in my mouth, helped test for further indicators with a taje home device (no extra charge), and ultimately got me informed enough to go seek outside help. This did not benefit his practice by doing all this. He just cares about his patients! Also, the whole staff is incredible! The hygienists are really sweet and gentle. The front office staff are kind and make sure to get you scheduled for your appointments and check ups to take advantage of the cleanings and services that are typically covered already by insurance!

I have been going to Dr. Diez for over 20 years but last week I had a problem and had to have a bridge done and a tooth removed. It was the first time in years that I’ve had any major work done by Dr. Diez. I have to say he is wonderful! And his assistants Clarissa and Cristy made me feel so comfortable. I even got a call from Dr. Diez’ wife that night to see how I was feeling…Great Caring office and Great People that work there!

Sabie Bartoo (Source: Google)


My husband & I are long time patients. When I met my husband he was not a fan of the dentist, however because of his experience with Dr. Diez’s (both Dad & son) he now takes really great care of his teeth! I have always taken good care of my teeth, but truly they are the very best dentist I have ever been to. They also have awesome hygienist and amazing office staff. Both my husband & I look forward to our semi annual visits, we feel like we are visiting old friends. I have referred many friends to G & C Dentistry & will continue to do so, they are the best in the bay! Sabie Bartoo

I was referred to Dr.Randall Diez and I’m forever grateful to have found this wonderful practice. It was by far the best dental experience I’ve ever had! From the warm welcome by Lori at the front desk to Claudia who was assisting Dr.Diez, I can truly say I have never felt more relaxed at a dental office. Throughout the procedure, I was asked about my comfort level and most importantly, I never felt any pain. Dr.Diez is truly the best at his job and has erased any anxiety and fear I had prior to finding General & Cosmetic Dentistry of Tampa.

Camaron A. from Riverview, FL (Source: Yelp)


I was referred to Dr. Diez by a good friend who has been going to him for some time and can never say enough about how wonderful he and his office staff are. A recent change in my dental insurance made it possible for me to give them a try. Normally I wouldn’t write a review about a dentist but after my experience I felt compelled to. Dr Diez and his staff were the best dentist I have ever been to and I have been to some posh dentists in NYC and they don’t even compare to the overall friendliness , professionalism , care and concern that I received today at their office on W. Kennedy Blvd. Everyone at his office was exceptionally friendly, they honestly make you feel like they are there to help you and not like as in most dentists I have been to in my life that are more unfortunately concerned about their bottom line than what’s best for the patient. I as most people fear the dentist and usually put it off until I am in pain and scrambling to find a dentist for fast relief. My first visit was mainly for X rays and a check up and cleaning, sounds simple enough but as in the past , even those procedures have been painful. My experience today went flawlessly without the slightest discomfort and during the procedure Alicia the super friendly hygienist was constantly attentive to make sure I was not experiencing any pain. If your looking for a new dentist or if you haven’t been to the dentist in too long, I sincerely recommend calling Dr Diez and his staff, I assure you won’t be disappointed and you too will be here sharing your great experience as well. Parking is a bit tight upfront and can be difficult backing out on to Kennedy Blvd, but they do offer parking in the rear as well.

Everyone that I came in contact with from the front desk up until I saw the dentist were polite, professional and knowledgeable. They explained what procedure they were doing and the reason why. After completing the exam they explained what they had found and suggested treatment options. Felt no pressure. Today was my second visit…interacted with different employees but the results were the same…excellent.

Gene Steff (Source: Google)


I came here for a second opinion after another dentist recommended what turned out to be a completely unnecessary procedure. Dr Diez was great at explaining the situation and helped resolve my issue in a much easier, and cheaper, way. He also performed some fillings and they were practically painless. So happy I found this practice.

Fay Kazbour (Source: Google)


I’ve never been more satisfied with a Dentist before! I was referred here and glad I made the change. All the girls in the front were very welcoming and nice especially Pam, she thoroughly went through the costs of a procedure and wrote down all the dates the surgeon was available. The Dr. made sure all my questions were answered and the hygienist made it such a quick and comfortable cleaning. Such a friendly atmosphere! They all made me smile and laugh and I wouldn’t go anywhere else. They deserve more then 5 stars.

Heather Hubertz (Source: Google)


I was referred to this dentist office by my boss who has been coming here for years and now I know why. This is a family dentist unlike those corporate dental offices where you feel like a number. I feel so welcomed by friendly staff but more importantly my dental cleanings are always pain free and very thorough. The health of my teeth and gums have improved since I’ve been coming here. I’m a very satisfied patient.

Amanda Gallo (Source: Google)


I received a crown at this location and had a pleasant experience overall. From the front desk to the exam room, everyone I encountered was polite and kind. I was able to get fitted and have my crown implanted in the same day by Dr. Diez. He is a very patient and kind dentist, taking the time to explain everything in a way that is comprehensive and thorough. I am very pleased with my experience here and would highly recommend coming here for any dental work.

Erin Green (Source: Google)


I love this practice! Everyone is so nice and helpful. The hygienist are amazing, my teeth have never been cleaner. Dr. Diez is honest and very informative, best dentist I have ever had. I have never waited more then a couple minutes (if any) past my appointment time to be called back, which is very rare at many medical offices. This is a great dental practice and I highly recommend it.

Lee Ann Macy (Source: Google)


I highly recommend Dr. Diez. He explains everything so well and l always trust him. He is gentle and always makes me feel comfortable , which is hard to do because I get nervous when I go to the dentist. As a bonus, he has a great staff. The employees are kind, cheerful and helpful. They always have a smile and great attitude.

Chris Rizzo (Source: Google)


I selected Dr Diez about 5 years ago and I’m extremely happy with the service, staff and most importantly the dental care I’ve received. The entire staff goes out of their way to ensure your appreciated. From the greeting when you first arrive, to the excellent dental assistants that do the cleanings, to the extensive knowledge of Dr Diez and his son. If your smile is important to you, give this team a try, you will be very happy you did!

Hannah Robson (Source: Google)


I am so happy I found this office! I am new(wish) to the Tampa area and had been putting off finding a dentist because I was scared of being judged for having so many dental problems so young. After breaking a front tooth I had no choice but to find someone to fix it and being a completely new patient Dr. Diez fit me in 2 hours after I called, after a Holiday weekend, on a Monday. The entire staff was so friendly and made me feel so welcomed and I really feel that I am in good hands here and will finally get the smile I’ve been wanting. I am so happy I am now a patient of this office and just wish I had found it sooner!

Chad Zintel (Source: Google)


My old dentist passed away a few years back and I struggled to find a new dentist that was as knowledgeable, caring, and friendly until I came across Dr. Diez and his staff. Right when you walk in you get a warm greeting and that experience continues all the way until you walk out the door. Dr. Diez takes care of everything in house – anything I’ve ever needed done has been taken care of in his office. This wasn’t the case for many dentists I have been at in the past who would refer you out to other specialists, surgeons, etc. If you are in the market for a new dentist I would highly recommend Dr. Diez.
