Jonathan Montoya, DDS
Dr. Jonathan Montoya began his dental journey as a dental assistant at a pediatric dental office where he quickly realized: we are all kids at heart.
As a military child and son of two mental health care professionals, Dr. Montoya decided to dedicate his life to making the dental experience as minimally miserable as possible and, dare he say, enjoyable!
Dr. Montoya spent three years working closely with world-renowned dentist Gordon Christensen at CRA now known as Clinicians Report®. He spent years studying dental materials, assisting with material and dental science projects, and even attending all available advanced training for experienced dentists given through Practical Clinical Courses. This experience set the foundation to a powerful early career.
Dr. Montoya started his college career at Utah Valley University studying Business Management, and he went on to earn his Doctor of Dental Surgery from the University of North Carolina-Chapel Hill, which is considered to be one of the top three dental schools in the world.
Post-dental school, Dr. Montoya launched his career in an extremely busy corporate clinic in southern Chicago. He averaged doing the same procedures in a month that most dentists complete in a whole year! Dr. Montoya’s wife decided she wanted to further advance her career in orthodontics and got the news she was accepted to UF College of Dentistry.
As part of his post-dental school training, Dr. Montoya invested nearly all his income into receiving the most prestigious and advanced training in cosmetic and implant dentistry. Dr. Montoya is now a Fellow of the International Congress of Implantology, an Implant Pathways Fellow, a Fellow of the American Academy of Cosmetic Dentistry, an Accredited Member of the Academy of Facial Esthetics, and a member of the American Academy of Implant Dentistry.
He recently also completed advanced training for oral and IV sedation from the world-renowned Stanley Malamed and Ken Reed. Dr. Montoya has rehabilitated over 300 wonderful patient smiles and is currently a Roving Implant Specialist for several dental offices around the state of Florida. In 2023, he will complete his advanced training in Biologic Bone Augmentation in Frankfurt, Germany, as well as more training in IV sedation at ASAASD.
When Dr. Montoya isn’t doing dentistry or dental-related training, you can find him doing other dental-related philanthropic work (he’s a dental nerd). Dr. Montoya is a Clinical Adjunct Professor at the UF College of Dentistry, where he teaches general dentistry and volunteers at the Freedom Clinic in Ocala offering community members free dentistry from the students via his supervision.
Other than anything actually dental-related, Dr. Montoya has a wonderful wife and two sons (Jett and Jaden). He enjoys spending time with them, as well as going camping, playing soccer, free diving, and traveling. If Dr. Montoya looks vaguely familiar, it’s because he appeared on America’s Got Talent in 2015 as a singer…he ultimately had to choose between being a dentist or a professional musician!
Rose Johnson, DDS
Dr. Rose Johnson spends a bit of every day simply being thankful. Part of this is being thankful that her profession is her passion. Dr. Rose and her husband (and fellow dentist) are self-proclaimed dental nerds. They love what they do and it shows every day with every patient interaction. They met in dental school and welcomed their first baby girl this January!
Dr. Rose is now continuing her education at the University of Florida and will soon earn a Mastership in the Academy of General Dentistry.
Dr. Rose grew up in Arizona. After graduating from college in Flagstaff, she moved to Denver to study dentistry. After earning her DDS, they moved to sunny Jacksonville where she joined our dental office. Outside of the office, she enjoys dining, traveling, and the outdoors.

Samuel Posze, DDS
Dr. Samuel B. Posze brings a compassionate, patient-centered approach to dentistry, rooted in a deep belief that quality care begins with communication and trust. Born in St. Paul, Minnesota, Dr. Sam spent much of his childhood on the move—including two formative years living in Asia—which gave him a broad perspective and a genuine love for connecting with people from all walks of life.
Homeschooled throughout high school, Dr. Sam pursued higher education at Mississippi College, where he earned his degree in Biomedical Sciences with a minor in Chemistry, graduating Magna Cum Laude. He went on to complete his dental training at the University of Tennessee Health Science Center in Memphis, where he honed his clinical skills and deepened his passion for serving others through dentistry.
Dr. Sam is known for his calm demeanor and ability to put even the most anxious patients at ease. He takes great pride in transforming nervous newcomers into confident, relaxed patients—many of whom leave the office with a newfound appreciation for dental visits. While he practices the full scope of general dentistry, he has a particular passion for oral surgery, crowns and bridges, and esthetic dentistry. For Dr. Sam, there’s nothing more rewarding than helping a patient rediscover the joy of their smile—especially when that smile has long been a source of discomfort or embarrassment.
A lifelong learner, Dr. Sam is committed to staying at the forefront of his field through continuing education and self-directed study. He also volunteers his time at a local free dental clinic, helping to provide care to those who need it most.
Outside the office, Dr. Sam enjoys an active lifestyle filled with weightlifting, golf, and outdoor adventures. He’s also an avid reader, and loves spending time with his family and girlfriend, Kelsey. He is deeply involved with his church, and his faith plays a central role in both his personal and professional life as the driving force behind his commitment to excellence and his belief in treating every patient with honesty, dignity, and love.
Dr. Sam is honored to be part of your dental journey and looks forward to helping you feel confident, comfortable, and cared for—every step of the way.

He attended hands-on implant courses from coast to coast, where he learned directly from leading surgeons and prosthodontists in the field. He continues to refine his surgical and prosthetic skills through intensive CE on complex cases involving full-arch restorations, overdentures, and immediate loading.
From guided surgery to restorative excellence, Dr. Asturia brings a thoughtful, evidence-based approach to implant dentistry, blending surgical precision with a deep understanding of prosthetic aesthetics and biomechanics.
Outside the operatory, Dr. Asturia is an adventurer at heart. He enjoys cooking, traveling, kayaking, fishing, and playing guitar. He remains actively involved in community service through dental outreach programs and mission trips, including international work in the Dominican Republic.
Whether restoring a single tooth or transforming an entire smile, Dr. Asturia approaches each case with the same care, dedication, and passion that brought him into dentistry in the first place.
