After consulting with a few cosmetic dentists, I decided on Dr Kantor, who was also highly recommended by my dermatologist, for my porcelain veneers. I liked that he has over 15 years of experience as a cosmetic dentist, performed thousands of porcelain veneer cases and was very impressed by his patient portfolio photos. I had cosmetic issues that were causing me not to smile: chipped front tooth, gap between my front two teeth, crooked bottom teeth, a crossbite, worn and yellow teeth. My teeth .. Read More

I haven't met a lot of people in my life who are as good at what they do as Dr Brian Kantor. The level of care and professionalism over many years is immeasurable.

One month after receiving a new set of veneers and I can honestly say I am thrilled with the results. Dr. Kantor is an incredible artist, and an even better person. He took the time to listen to all of my requests and thoughtfully weighed all of them and discussed all of them with me. The experience was incredible start to finish and I now have the smile I always wanted. Thank you to Dr. Kantor and all of the wonderful staff that made this experience, and the results, more than worth it!


I have been going to Marc and the team for 33 years, first coming at age 23 because of inflamed gums that occurred after a visit with a different dentist. I thought I had something awful! From that day Marc calmed and assured me, and made me laugh, he is kind and very knowledgable. I feel so lucky for the day my colleague recommended Marc to me. It is something in this day and age to look back and know that there has not been a single visit I felt the need to question the skill or treatment I re.. Read More

If there were 10 stars Marc and the team would get them! Ellyn S.

I am always pleased when I see on my calendar that I have an appointment with Dr. Lowenberg. Without question he is one of the most wonderful people I have ever met. Doctors Lowenberg, Lituchy and Kantor are all experts who with confidence, care, and understanding serve their fiercely loyal patients the best dental care possible. The office staff is a true reflection of the high standards set forth by these three geniuses. But what really makes me smile is knowing that when I leave a visit with .. Read More

When I walked into the LLK office, I didn't realize how great a dentist could be. He was Dr. Brian Kantor who did an amazing veneer job on my teeth which has resulted in innumerable compliments on my youthful smile. I also noticed that it isn't just him, but the other partners work well together as they interact with each other and there seems to be a general feeling of congeniality in the entire practice. I have highly recommended them to others and continue to do so.

I met Dr. Lituchy through a friend. I was not happy with my smile but thought it was "just ok." Dr. "La-Tooch" as I refer to him, showed me how it could look. I was relaxed the entire conversation. Within 30 minutes, I was ready to set the appointments needed and move forward with my new teeth! That was one of the best decisions I have ever made. I am no longer self-conscious when I smile. I just know that my teeth look great and that I can stop worrying if they look "good enough." I am thrilled.. Read More

"Good, better, best. Never let it rest. Til your good is better and your better is your best." - St. Jerome Drs. Lowenberg, Lituchy & Kantor are dedicated to making the good become better and the better become the best. Their office is the total package, and I have ultimate confidence in their entire team. Dr. Lituchy inherited me many years ago when a string of prior dentists, despite being highly competent professionals, could not solve my dental issues and achieve the natural look that I wan..

Dr. Lowenberg has been my dentist for 25 years. He's simply the best!! Both Dr Lituchy and Dr Kantor are as well. During the course of time they all have taken care of me and are equally wonderful!! Everyone there is; I would never go anywhere else. Quality service and a warm and wonderful environment. It feels like home - I know - an odd association with a dentist office. My husband has been with Dr Kantor for a decade and raves too


Drs. Lituchy and Lowenberg and their staff were very friendly and treated us in such a professional manner. Both of us are very happy with our beautiful teeth and great smiles. We both had complete restoration of our upper and lower teeth. Every visit to their office was pleasant and we commented on how quickly the time went considering that our office visits were lengthy. We continue to return for repeat check ups and cleanings and highly recommend both Doctors.

I have been a patient of Greg Lituchy's for longer than I can remember; probably close to 30 years. Greg was actually cleaning my teeth when we first met. I had an intense fear of Dentists; bad childhood experiences, and hadn't been for years. In one visit I was hooked! I LOVE Dr Lituchy. I have had many issues with my front tooth, and Greg figured out the most cutting edge way to deal with it. For a time there, I was seeing him frequently - and he replaced my front tooth with the most precise a.. Read More

I had heard about Dr. Lowenberg for years, read articles about him and seen him on TV shows, so when I finally decided to improve my smile, I went to him for a consultation. I was shocked how expensive transforming my middle age smile into something more youthful would be, but I was so impressed with how down to earth and humble Dr. Lowenberg was that I decided to invest in my mouth and my future. It's a year later and I still cannot believe how amazing he made me look. Every time I look in the .. Read More
