Reviews
I had a question about how my partial fit after having two temporary caps. I was given an appointment that day, taken in as soon as I arrived and given VIP service to fix the problem. The nurse was beyond nice and was determined to fix the problem ... which she did. I could not have been treated nicer or more professionally.
Quality service, friendly personnel, good atmosphere, good dentist!
My experience with the Grelot Dental Group was very good! Very friendly personnel with beautiful smiles and I felt very welcome. Loved the Christian music playing in the Waiting Room! Hygienist was very thorough and did a good job cleaning my teeth! Dr. Sitz took his time explaining answers to questions thoroughly. My husband and I both agree our experience with everyone at the Grelot Dental Group was an excellent one.
Very friendly, competent staff all around
My dental hygienist, Mary Katherine, caused me no discomfort; very friendly and put me at ease. Dr. Stine always very professional and puts me at ease, answers all my questions. The front desk personnel and insurance personnel provided good resources regarding dental insurance needs.
Painless
Another great experience. Thank you to Doctor and staff.

Top notch service
The hygienists and dentist there are all friendly, professional, and you can tell they love what they do. During my procedure and my recovery I felt no pain at all. If you are nerves of the needle this is a place of no worries.
Professional and informative. I'm a nervous patient and they were reassuring.
Excellent service with no delays.
I have never been disappointed with my service at Grelot Dental. Among the things I like most are: timely reminders, ease of changing an appointment if necessary, and courteous and helpful staff at all levels.
Great service. Great Quality. Good friendship feeling. Everybody was positive and cheerful. Excellent staff. George Sumrall
I was very surprised to find I had a different dental tech. I feel you should advise your customers of such changes before they arrive for the appointment. Jana did a fine job, no problem with her. It is just I had used Debra for nearly 20 years and I missed her.
Good Visit
I needed exam to determine issue with tooth pain. Got into sear To quickly, X-ray was done and Dr Steen diagnosed problem very professionally.
Very nice and professional staff
There were a lot of new faces, but all were very friendly and knew their job well. They were also informative about everything they were doing.
The cleaning I received today from Jana is the best I have ever had. The office personnel are so friendly and helpful.
Pleasant visit with a good amount of smiling :)
A streamlined and fun visit to Grelot Dental. I laughed and smiled a good bit talking to my hygienist and dentist. Thank you for doing a great job!!
Great experience
I have been a long time patient at grelot dental. Over the last couple of years with the sale of the practice, there have been numerous changes in staff. Typically, this would deter me from returning. However, i have yet to have a bad experience with any new staff. Have had the pleasure of meeting both new doctors in the practice. Dr. Steen and Dr. Sitz are both friendly and professional. I have had extensive work done by Dr.Sitz- all was a pleasant experience. Mary Katherine did a wonderful job cleaning my teeth today. I will continue to be a loyal Grelot Dental patient and recommend to others!
Friendly, Caring, and Professional
Getting my dental needs taken care of at Grelot Dental Group is always a pleasurable experience. Whether it is routine or emergent, I am always greeted with a friendly smile and caring environment. Nothing is left to chance by anyone, from the Doctors to the receptionists... everyone is there to see that your needs are met.
Great staff!!
Everyone was so kind and courteous. I enjoyed my visit.
Very good appointment
Every thing went as I hoped. First time I ever got the shots where it didn't hurt at all. Made the whole deal so much better.
Excellent service!
Everyone is extremely nice and helpful. I have been going there for years and never wait more than 5 minutes for my services to start.
It was my first visit and I loved it!!! The staff made me feel at home and they were extremely nice. I went to get a cleaning by Mary Katherine and she did a fabulous job. I smile with pride now!! She was fantastic and she did a wonderful job. Thank you!! Will see them soon!!
Cleaning
Missed Donna. Hope she is feeling better. Enjoyed meeting Toni. She did a good job cleaning my teeth. Really like Dr Steen.
Calming atmosphere
The staff is very friendly and knowledgeable. I used to be afraid of dentist but not anymore
Great service, positive employees
Everyone was friendly and helpful. Good job done. They were very positive. It was overall a very positive experience.
Excellent care with a professional staff
I showed up at Grelot Dental with an emergency. Three hours later I'd had the procedure that took care of it--was feeling much, much better. Home now with minimal pain.
Professional job on me with crown work.
I like my Dr. and assistant. Friendly. They explain the procedures ; no guessing what will be next. Have been using Grelot Dental for many years. Also my hygienist has been doing my teeth a great job.
Nervous
Yes I was nervous going in for my new crown. But I cannot say enough about my visit. Dr Steen put me at ease from the very start. He explained everything he was going to be doing and even distracted me enough that I forgot I was nervous. I had no discomfort and the procedure went very quickly.
Enjoyed my visit
Dr Sitz and his assistant took care of my problem of my problem in an efficient manor. Post procedure Haase been good. Pain has not been a problem.
Today was my first visit to Grelot Dental Group. The entire visit was like a breath of fresh air. Deborah, the hygienist was thorough and took time to explain to me her procedure. Although I have had every-six-month dental care for many years, I have not had such a thorough inspection and cleaning in over five years. Dr. Steen was very personable and impessed me with his knowledge and professionalism. He recommended services to me and provided the estimated cost. He referred me to a periodontist for a specialty opinion. He understood that as an older person I would not want to invest vast amounts on optional treatment. I look forward to my return visit next week.
I visited Grelot Dental for a cleaning after seeing rave reviews online. The reviews were accurate. I had the most pleasant experience. Debora is a FABULOUS hygienist. I will never go anywhere else!!!
Wisdom teeth removal
Was very well done ^^ comfortable environment and professional service by Dr. Sikz. I hope I heal well and keep my record of good healthy teeth ;)
Very good service and dental work was excellent
I will continue to recommend them to anyone needing a dentist. I have had a lot of work on my teeth, both here,in Florida, and from when I was younger. Everything was explained before it was done which was relaxing for me.
Hygienist - 6 monthly check & clean!
Debra has been my hygienist for more years than I can almost count and I think she's the greatest. Very professional, friendly and reassuring. The lady at reception who booked me in for treatment was very polite and efficient too.
Good service, very professional, friendly atmosphere
Appointment was on time, no waiting. Work was very through. A good experience.
Great experience every time I visit Friendly and courteous people.
I appreciate the manner in which my Dentist strived to determine the nature of my issue and attempting to identify the matter. Hopefully, on the follow up visit, the discomfort will have subsided.
Professional and friendly staff and dentist!
Dr. Sitz and his staff are friendly and professional.
First time seeing Dr Stein. Loved him.

Grelot dental group
I have been going to this dental group for over 20 years and I have never considered seeing any other dental office. Group staff are always friendly and professional . Dental hygienist Debra is the best.
Grelot Dental is the number one place to go for great dental service! When entering the front door each person is greeted with a big smile and a friendly hello. Dr Steen always explains each procedure so thoroughly. Upon completion rest assured that you will be highly satisfied with long lasting results!
High Quality Professional Dental Service
I had a root canal done and the procedure was a very good experience. Dr Steen is excellent........I did not even feel the dreaded shot to numb my mouth. Very pleased with my new dentist .............he also has a great personality.
Superb service, very friendly
My daughter and I really like the new doctor, very friendly and detail oriented. Our new dental hygienist was also great. Oh yea, the office staff was also great.
It was great!! Everyone is so friendly
Awesome Dental Office
As someone who is weary and embarrassed to go to the dentist, I was pleasantly surprised by the staff at Grelot Dental Group. From the time I stepped foot in the office, I felt at home. When I went to the room to be seen, there was a sense of being comfortable with the down home nature of the staff. I'm in the military and I've been seen by many dentists all over the country and I can honestly say that I've never felt more comfortable than I did today. If you're considering them for your dental work, do it! You won't be disappointed!
Fast service, very friendly dentist.
Dr. Sitz was extremely nice and very thorough.
Great service
The staff was helpful and patient.
High Quality Professional Dental Service
I recently had an appointment for my 6 months check-up. The entire staff of support and professional personnel made my dental visit a most pleasant one. I also had the pleasure of meeting the new dentist, Dr. Steen (a really good fit). :) If anyone needs a new dental group, Grelot Dental Group, is the place to go. Always friendly, warm, and smiling people greet you and you get a sense of "home" while receiving high quality dental service. My husband and I feel like part of their family!

Best in Professionalism
The Staff and Dr. Sitz were very professional and helpful, in my having several crowns and dental cleanings done.

Dr.Sitz is very good with patients, and does excellent work.
I feel comfortable at Grelot Dental
I've been going to them for some years and love them more every time..Dr Sitz is a great new addition and came to my rescue this morning when my jaw locked up during my cleaning
Good experience this morning getting first step of crown done. Staff and dental tech very courteous and polite.
Very professional and friendly.
My experience was great! I had a tooth extracted to prepare for a "4-tooth" bridge. Dr. Sitz and assistants were wonderful getting me through the work that I needed. The bridge looks terrific. I am grateful for the care I received.
Excellent service with no delays.

The doctor is very knowledgeable, efficient and personable. The assistant was very helpful and personable also. I would recommend their services. Appointment reminders via text and e-mail are very beneficial.
Very professional and caring.
They took very good care of me.
Very friendly staff. The dental assistant did a wonderful job of making me feel comfortable with my procedure as well as informing me of exactly what was being done and why. I did not feel as if I was talking to a stranger at all.
That are good to me. I like them all
That are good to me. I like them all
This group of dental care has been my favorite for years. Great service, great people, and the best customer service ever. I'm proud to be a client of this group. Dr Miller (my doctor for years has retired) sad face. He was very nice.
My first two (2) experiences with the new group were been very positive and I look forward to another long term run with the new group.
The reception area is clean and comfortable. The front office staff are all very friendly, pleasant and helpful. I love my Hygienist, Debby. Dr. Riley and his Assistant were both gentle and kind. All in all I had a very pleasant experience even though my treatment required a lot of time.
Could not have asked for a better experience undergoing a procedure that was no fun at all except for the good service. Regina was excellent!
Everyone here is so nice, caring and thorough! !
Dr. Pousson made me feel relaxed and comfortable. I also am confident in his ability to provide quality dental care. I feel sure he will be a great fit at Grelot Dental, and succeed in providing the standard of care created it's founders. He has some big shoes to fill (I was a loyal Dr. Miller patient), but I must admit, he is off to a great start. I will definitely be returning and recommending this practice to others.
You guys are awesome and I thank you very much and Dr. Riley is going to be great God bless
I had a great experience in the office. My hygienist Michelle was so sweet, and very thorough.
Very good in caring for patients. " Professional dental work is their style; you will be very happy with your smile."
