Dr. Sam Callister

Dr. Sam Callister is a third-generation dentist who is passionate about providing personalized, patient-centered care. Following in the footsteps of his father and grandfather, he developed an appreciation for dentistry at an early age and was drawn to the profession by the opportunity to serve others and build lasting relationships.

Dr. Callister earned his Bachelor of Science in Biology from Utah Valley University and his Doctor of Dental Medicine degree from the University of Kentucky College of Dentistry. He approaches patient care on an individual basis, recognizing that every patient has unique needs, goals, and concerns. He believes that the foundation of excellent dental care is trust, communication, and genuine relationships.

One of Dr. Callister’s favorite parts of dentistry is getting to know his patients beyond their dental needs. He enjoys hearing their stories, learning about their families, careers, and interests, and helping them feel comfortable and confident throughout their care. His goal is for every patient to feel valued, respected, and well cared for.

Outside the office, Dr. Callister enjoys fitness, golfing, trying new restaurants, and spending time with his wife, their nine-month-old daughter, and the family dog. He looks forward to becoming part of the community and building lasting relationships with the patients and families of our practice.

Dr. Nathan Green

Nathan Green is a Doctor of Dental Medicine and proud 2026 graduate of the University of Kentucky College of Dentistry. Originally from the North Shore of Oahu, Hawaii, he made his way to the Bluegrass State for dental school and never lost his aloha spirit along the way. Nathan has a passion for endodontics and general restorative dentistry, with a commitment to delivering thoughtful, high-quality patient care.
A proud member of the Big Blue Nation, Nathan bleeds blue on game days — though his loyalties also extend to the Utah Jazz, Utah Mammoth, and the Buffalo Bills. When he’s not in the clinic, you’ll find him spending time with his wife and their golden retriever, Gusgus, or out logging miles on the road as a self-described “aspiring hobby jogger” who occasionally tackles a marathon or two.

Dr. Stephen Daniels
