I was very impressed I have A 2 year old and he was very patient and he gave me advice on how to hold him during his cleaning and my son took to him well he didn’t put his self on him he didn’t scare him he understood that that was a fearful experience for two you’re old so we will definitely be back.

Amazing staff! The blonde women who helped re cement my crown was surperb. She tried for 30 minutes to fit and re fit my crown. At any point, she could have given up and said it would not fit. She saved me a lot of money by allowing me to re use my old crown instead of having to pay for a new one. It gave me a sense that this company is not about squeezing every penny out of their patients. I really appreciated that. Also, the decor and atmosphere of the building is great. Design is very welcoming and warm. Love the candles

Had my first appointment since my teeth have completely decayed and was terrified of treatment and judgment. Dr. Sefcik was very personal and caring with me, and although I was getting bad news he made sure to be supportive and optimistic. Felicia also came and explained how we could pull this off financially in a manageable fashion and continued to talk me through the harsh news and made me feel much much better about what my future was gonna end up looking like. It was very rough news but I’m so glad it was through them. If my previous dental experiences had been this comfortable I wouldn’t be in the position I am today. I’m very thankful that I have something to look forward to now!

I had been terrified to go to the dentist but a wisdom tooth became an issue and I knew I had to get it taken care of. I found Dr. Sefcik and was able to get an appointment the next day. I was called back within 15 minutes of finishing the initial paperwork and had an amazing assistant take all my x-rays and the doctor was in right after that. I never once had to question where the doctor was and he was sincerely interested in calming my fears and addresing the issues to be taken care of. I had two wisdom teeth pulled and a deep cleaning of my upper jaw. After a short nap I was up and feeling great for the rest of the day! I could not have asked for a better experience and would recommend Dr. Sefcik to ANYONE!

Most helpful dentist we’ve seen! I have been looking for someone that will work with us on my husbands mouth and I’ve finally found one. I’ve heard “I can’t help you” or given a referral and left to deal with it on our own. Its really hard to explain the whole situation but I am very thankful for the way this appointment has panned out.

I’ve already recommended this office to everyone that will listen! I had the most wonderful experience. I’m so happy to have finally found a dentist that I feel comfortable around and trust. Everyone was so great with both of my boys (1 and 3), during their very first dental exam. They made sure they were always smiling and allowed them the time to adjust. I never felt rushed or like we were annoying anyone when

Dr. Sefcik is very patient focused and engages the patient in the processes and possible treatments. We thought he was thorough and gave every evidence of high professional standards, His office and technical staff appear well qualified and the reception and general atmosphere is very pleasant.

I thought I was going in for a cleaning – as I chose on ZocDoc, but only received Xrays and a quick exam. The whole thing took less than ten minutes. I had to schedule another time for cleaning and cavities, which was weird. Also, the country music playing was awful, but the treatment I received was still very good, fast, and the dental assistant was great.

Very nice and welcoming place to have your dental work done!!! Everyone that I encountered at Lighthouse was friendly and caring… made me feel comfortable and at ease. Also if you get the sisters they will crack you up 🙂 it was a great distraction from my anxiety as I was getting my work done… Just a great place, I will defiantly go back and recommend to anyone who needs a dentist. I had the pleasure of working with Gregory Sefcik, DDS. He was also very caring and fixed up a tooth that was fudged up by comfort dental years later. Lighthouse blows Comfort Dental out of the water. Thanks Lighthouse!

Dr. Sefcik took the time to answer my questions yet again, including which procedures I need to have done immediately, and the importance of schedualing them A.S.A.P. He is extremely knowledgeable and very good at explaining coditions, procedures, and outcomes, as well as the consequences if these aren’t done. He did not talk “down” to me,either. Oh, one other tiny little comment, he’s really easy on the eyes!

Tiana M (Source: Zocdoc)


He was very friendly and knowledgeable, he explained everything in ways I could understand and was patient with me. The whole staff was amazing and made sure to take their time so that my teeth were fixed right the first time. I have always had a lot of problems with my teeth and past dentists always made me feel self conscious and rushed. Dr. Gregory actually sat down and listened to what I had to say and took into account what i wanted for my teeth as well, instead of just telling me what he wanted. He made sure we were both happy

I really enjoyed my visit with Dr. Sefcik, he was thorough and gentle in his exam, he cleaned my teeth himself and his work was painless and quick. He showed genuine care for me as a person and patient. His staff were warm, respectful and welcoming. I loved that my whole visit was interactive, inclusive, and informative. The rates are very reasonable and they tell right up front what the cost is before doing work and everything was all done in one visit! When I left his staff made sure I booked my 6 month follow up cleaning.

It was quite comfortable, and quick. Mr. Sefcik was very informative, understanding, and very professional. The office technology was impressive and very organized. The staff was very kind and opening, specially Felicia. I definitely will continue to come back and definitely plan to recommend this office to many others. Thank you all so much. Until next time, Lakerisha.

Gregory Sefcik and his staff were amazing. They were very nice and easy to talk to about any treatment or diagnosis. Very understanding about pricing and also would give you a breakdown On what needed to be done. Staffing was very polite and professional. I would highly recommend Lighthouse dental to anyone.

I took my daughter to see Dr. Sefcik, and we really liked the nice, family feel of the place. The ladies who work with him were friendly and helpful. She was seen right away, and the Doctor was nice, professional, and knew the ins and outs of insurance well enough to advise us exactly what would be covered. He was insistent on good dental practices without scolding or making my daughter feel wrong. He made us both feel very comfortable.

The dentist Dr Sefcik was through. He answered every question I had for him. I will totally trust him with all my dental problems. I also would send my family and friends to go see him In fact my daughter recommended him . Thanks to you and your courteous staff.

Pretty long wait time when you show up for your appointment on time however, everyone was friendly. The room where you are seen has huge windows (which is nice). Dr. Greg was confident and flexible and his staff was awesome. My only complaint? I am in extreme pain and left with an earache and shooting pain up my face. I think that a prescription of some sort would have been a better resolution in waiting for a future appointment. All in all when the work is done I will be a happy return customer.
