Our mission is to offer patients the finest dental care. We recognize that your time is valuable, we do not double book patients, you will be seated at your appointment time and we will work hard to get you on your way. Your first appointment will take time, once we figure out your needs and parallel them with what we can do we are confident we can deliver the smile you are looking for.

I recently moved to this area and needed a new dentist for my boys (ages 2 and 3) and myself. We tried out Tambrini and loved it. They have toys in the waiting room for the kids. My oldest son warmed up to the idea of seeing a dentist right away. My youngest was unsure the first visit but was much more receptive by the second visit.
Services
Dr. Seth Tambrini knew he wanted to be a dentist as early as his freshman year in high school when he was still living in Lansing, IL. After graduating with a degree in Biology from The University of Illinois at Chicago he attended Indiana University School of Dentistry. After working in Indianapolis for 2 years he returned to the area and opened up Tambrini family Dentistry.
As a new patient, being well-prepared for your appointment will ensure that the doctor has all of the needed information to provide the best possible care for you. For your convenience, we have made the new patient forms available for you as PDF documents, which you can print out in advance and complete in the comfort of your own home (you should have a total of 4 forms).

Dr Tamburini and his staff are absolutely informative, knowledgeable and most of all caring. Amanda and Bobby have impeccable bedside manners. They are very intelligent and experienced. I have never met a dentist like Dr Tamburini who is absolutely the #1 most caring, professional, intelligent dentist in NW Indiana. This office is highly recommended.

This morning I had the first visit for some extensive dental work, including filling repairs and replacement, along with a crown replacement. I have been to approximately five dentists in Illinois and Indiana, as well as orthodontists. I have NEVER received such thorough examination, diagnosis and treatment as I have with Tambrini Family Dentistry. Dr. Tambrini and his staff are PHENOMENAL! I tend to be quite anxious when I need fillings and Novocain shots. However, the nitrous gas offered while having work done was the best thing for me. I did not feel anxious, the pain of the shot was not intense

If you are looking for a dentist, I highly recommend Tambrini Family Dentistry. My previous dentist retired and I found myself dealing with the new group that took over the office and patients. I never knew what dentist would be attending to my needs. I received a referral to Tambrini Family Dentistry from another dental professional and have been very pleased. They are very professional, knowledgeable and caring. I've never had an issue having to reschedule an appointment (Donna and Holly at the front desk are awesome!) They don't keep you waiting to be seen. Dr. Seth and Amanda replaced a front

Beware if you cancel they want to shame you if life happens and you call and want to reschedule your appointment. Smh. Really sad they’ll deny you and not help you. Life happens!!! Especially with Covid and everything going on they should be the most understanding at this time!! Never again will I ever step foot in there!!

The moment I walked in I felt the positive energy!
Love The Crew. It was so many names I forgot lol. Very clean and all smiles. They work together as a team while doing my gum check. I’m very attentive to detail. And they are very organized and well kept up. It was very first time here. From the signing of the papers to the end with dealing with my insurance. It was a breeze. Even tho my insurance didn’t take them , I will still be back for my cleaning and maintenance. Thank You Tambrini Family! You guys really made my day !

2 words! Hands down….. Dr. Seth and his staff are amazing, from the front desk all the way to the other rooms. May I add it’s very clean and Dr. Seth and his staff makes you feel welcome and like family. What I love most about Dr.Seth is he’s very through and any questions you may have he will answer them for you and he don’t hurt you. The 2nd thing I love is all the staff they make you feel comfortable as well. Everyone has smiley faces and they talk which I love. I would recommend Dr.Seth to anyone. Thankyou Dr.Seth for all that you do and your staff.

I had a wonderful experience at Tambrini Family Dentistry. The staff was very patient and understanding. The procedures was explained to me in details.on one occasion, I was more than an hour late, the staff made it possible for me to see the dentist. I pray that GOD will continue to bless and keep all of them.

I went to Tambrini Family Dentistry as a new patient. From making an appointment with Holly and checking in and out with Donna was a real pleasure. From my experience usually dealing with the front desk has not been so easy. So thankfully no worries there. Kim and Kylee the Hygienists are very thorough and take their time to go over everything with a calm and patient manner. Dr Tambrini is also thorough and take time to examine you and explain things to use. You don’t feel rushed. I felt like I was cared for and I feel that every one knows their job very well. I was seen about 5 minutes after

Dr. Tambrini and his staff are AMAZING! I have never been to a dentist where everyone there has been so kind, understanding, compassionate, and incredibly knowledgeable. I have lots of anxiety when it comes to dental work, but this office has put me at ease and I know I am in good hands. I will recommend them to everyone I know! If you are looking for a dentist, look no further!

I can't speak highly enough about Dr. Tambrini, his staff or his office! I've had extensive dental work this year and consider myself blessed that I chose him after moving to Dyer last year.
He and his staff are talented, kind and personable. The office is new, modern and spotless. They even have TVs mounted to the ceiling so you can view them from your dental chair with a back massager option!

My initial impression was good given my family referred me to this dentist. My first visit was to review work from another dentist that led me to another referral to fix a tooth via root canal. His referral was another great dentist that fixed and saved my tooth. The next step was going to schedule time with Dr. Tambrini to place a crown.

This is when I started having issues with the practice so I am unsure if the issue is management or the doctor. When they reviewed my work they started to invoice me after they said they would not charge me for the visit and review. They made that promise and

I would go somewhere else. There are plenty of other dental offices in Northwest Indiana that would provide better customer service.
Canceled an appointment and provided over 48hrs notice. Later the next week, received a $45 cancellation fee in the mail. Spoke to manager and she stated it has to be 48hrs business days. The form on their web site and the form you fill out does not state "business days", it clearly states 48 hours notice. The manager says to me in a snide remark, "well its obvious its business days".

Why would I want to go back and be treated like that? I&apos

Great staff all together. As soon as you walk in the door the front desk is very welcoming. Dr. Tambrini was very informational. He was great letting you know exactly what you need. The hygienist Kim was also great! She explained everything step by step. The office is extremely clean. I highly recommend this dentist office!

FINALLY! A dentist I love with a great staff. They fit me in right before the end of the year when I lost a crown. They are always on time and upfront about the costs.

Dr. Seth is funny and kind. He is experienced but still young enough to be up on dentisty stuff. They offer gas and know what I can and cannot do without it.

I'm as happy here as it is possible to be with a dentist.

Dr. Tambrini is a young and coming dentist with alot to learn in regards to customer/patient satisfaction as well as learning to make better business decisions for his practice.
I was a patient of Dr. Tambrini for only two years and I am very dissappointed with his unprofessional behavior. I was scheduled for a recheck on a tooth that was supposed to be free, however, I was being charged for the visit. I respectfully questioned the charges to the receptionist. During the visit I asked Dr. Tambrini to check another tooth since I was partially charged for the visit. Dr. Tambrini wasn't happy
