Wellspring Dental

Your Dentist for Smile-Music in Motion

This Florida native is more than excited to call Brooklyn his home – he is activated. “Someone told me a long time ago that you can judge the quality of a doctor by how much time they spend with you the first time they meet you – that’s something I’ve taken to heart. Dr. Zientz and I were inspired to start Wellspring Dental with the hope that we could really get to know our patients as neighbors, really take care of them and treat them properly. We are working to build a relationship with you so that by the time you leave you’ll feel you’re better off than you were when you came in.”

Dr. Claassen attended the University of Miami Frost School of Music before pursuing a career in dentistry. He may be a classically-trained cellist, but he absolutely lives for dentistry. He graduated from the University of Florida College of Dentistry and completed his residency in Bangor, Maine – spending much of his time serving the less privileged of the community.

Outside the Office

Before he moved to the city, Dr. Claassen had his own hops farm in Florida. No wonder he is such a fan of Brooklyn Brewery! On the weekends, Dr. Claassen likes to practice the cello, spend his time outdoors playing sports such as basketball, exploring the city, or eating his way through all the cuisines and flavors that NY has to offer. “I enjoy Music of all kinds! I enjoy playing and attending classical performances as well as all the small music venues across Brooklyn.”

Professional Associations, Certifications, & Continuing Ed

Never one to rest on his laurels, Dr. Claassen is committed to continuing education. He finds introducing his Brooklyn Wellspring patients to advances in dentistry so motivating that constantly learning new dental techniques and technologies is one of his main priorities. On an ongoing basis, he furthers his training at the Dawson Academy for advanced dental education where he has achieved status as Scholar. He has also completed training in dental implants at the University of Miami, and he holds memberships with the ADA, NYSDA, and SDDS. Now that’s the dedication you can count on!
