Experience compassionate, confidence-building dentistry

Belterra, Dripping Springs, TX

Dr. Daniel Zaffetti discovered his passion for dentistry through a unique blend of curiosity, communication, and care. With a natural talent for breaking down complex ideas into simple solutions and a deep appreciation for human connection, dentistry became the perfect path—where science meets relationship-building. For Dr. Zaffetti, each day presents an opportunity to help patients feel more confident and empowered in their oral health journey.

Dr. Zaffetti earned his Doctor of Dental Surgery degree from New York University, where he cultivated a strong foundation in comprehensive dental care. Since then, he has continued to grow his expertise through post-graduate training in Dental Implants, Aligner Therapy (including Invisalign), Cosmetic Dentistry, and Occlusion. He remains dedicated to staying on the cutting edge of dentistry by keeping up with evolving technologies and techniques through continuing education.

Outside of the office, Dr. Zaffetti is passionate about fitness and movement. He enjoys working out, hiking, practicing jiu jitsu, and paddleboarding. His creative side shows through playing guitar, while his grounded nature is reflected in his love for meditation, breathwork, and deep, meaningful conversations with friends.

He has been a long-time member of the board of The Hope Institute for Children and Families and currently serves the organization as chairman of the Hope Foundation Board of Directors.

This partnership has made it possible for the dental practice to meaningfully employ and support a team member with developmental differences.

Besides caring for patients full-time, Dr Renken continues to create innovative solutions for the dental industry. As dentists and their teams are now providing a range of advanced procedures, he wanted to add a structure that would lend itself to consistent, and reliable outcomes for patients. Maximizing efficiency and organization in the dental care delivery system, Dr Renken invented and patented the Drop Delivery System where a dental practice can routinely provide any procedure in any dental setting. More recently, Dr Renken has been testing an innovative scheduling and rewards automation software called CareSchedule. The software is meant to optimize and simplify dental care appointments for patients and their dental practice. Currently testing, it is set to launch summer of 2020.  CareSchedule and the web-based patient subscription management platform, Health Assurance Plan, are part of the Springfield startup incubator Innovate Springfield.

As time goes on Dr Renken is devoted to finding new, tangible ways to express the values associated with the five values of Smile From Within Way. The sum of these efforts has become the Smile From Within Growth Platform. The goal continues to be creating greater health for team members, patients, and practices.Dr. Renken and his wife, Leigh have four children: Reilly, Miles, Oscar, and Lorelai, and a dog named Stella.
