The Place for Carroll Gardens Smiles

Tree-lined streets. Incredible diversity. Cultural heritage. And the feeling of a vibrant and flourishing community. We know why you love Carroll Gardens – we love it too and have created a dental office with all the neighborhood vibes anyone could ever wish for.

This is Wellspring’s startup location, and we have modeled our other offices on the creative blend of hospitality, elegant technique, and the lively but laid-back energy Brooklyn is famous for.

In fact, many of our patients tell us that coming to see us is more like a visit with friends than a trip to the dental office. You and your smile count. Every visit – every day.

Dr. Mitchell Zientz & Dr. Phillip Claassen

The dynamic, collaborative atmosphere at Wellspring’s Brooklyn location stems from the friendship and bond that was created between Dr. Mitchell Zientz and Dr. Phillip Claassen in dental school.

These roommates had a dream of creating a personal dental experience like no other – in a space that’s comfortable, welcoming, and warm. In other words, a place you actually look forward to visiting for your dental care.

Now, after several years in Brooklyn, this team is expanding their vision to other areas of the City, making high-level care accessible to everyone.

And because dentistry is their shared passion, both dentists spend all the time they can expanding their training, embracing new technology, and implementing the newest techniques modern dentistry has to offer.
