Triple Crown Dentistry was founded by Dr. Shields in 2012 with one mission, to build the best dental practice in the city of Louisville. It was decided from the beginning that our office would provide our patients with a dental experience that is pleasant and comfortable and that we would provide highly skilled compassionate dental care. We designed the office to have a warm elegant atmosphere with a feeling more like a home than a clinic. We invested in the best of modern dental technologies including: a paperless charting system, digital X-rays including 3D cone beam radiography, laser services, same day crowns/bridges (CEREC), and other state of the art equipment.

Our practice was built from the ground up, so we have a deep appreciation for every patient that we have and we treat them like family. Our care for our patients drives us to perform the best dental work possible and to continue to do anything we can to make the experience better. Dr. Eric Nunnally joined the practice in 2014 as the practice grew. With the addition of Dr. Eric and his training in dental implant surgeries and prosthetics, we were able to provide our patients with a full array of services in house without the need to send them elsewhere.  

At Triple Crown Dentistry, we continue to stay on top of the changing world of dentistry and regularly bring in new technologies that raise the level of care as they develop and become available. We are a highly skilled and sophisticated dental practice and plan to stay on the cutting edge of dentistry to always be what we first set out to be, the best dental practice in the city of Louisville.

Meet Our Doctors

Dr. Mary Shields


Dr. Shields is originally from Daytona Beach, Florida, known best for NASCAR, spring break and bike week. She completed her undergraduate degree at Stetson University. Her studies focused on biology, Spanish and art and she was a scholarship athlete (cheerleading). As an only child, it was difficult for her to leave home after college, but she felt like she needed to follow her passion and attend one of the best dental schools in the country. Louisville has been a great place to call “home” since 2004. She has wanted to be a dentist her entire life and fulfilled that dream by graduating from the University of Louisville. Her career goal became a reality when she opened the doors of Triple Crown Dentistry in May of 2012. She is most passionate about patient care and the trust she has earned with her patient family. Clinically, she focuses on cosmetic and family dentistry. Her strengths include working with children and those patients that lack confidence in the appearance of their smile. In addition to her traditional training in dentistry, Dr. Shields is pursuing a board certification in forensic dentistry, which allows her to help reunite loved ones that have passed away and are not identifiable by traditional means. Feel free to ask her more about this aspect of dentistry. She expects to become board-certified in February 2018, becoming one of less than 100 board-certified forensic odontologists in the world.

Dr. Shields loves the opportunity to work alongside her husband, Dr. Eric Nunnally, on a daily basis. She admires and respects his areas of expertise including dental surgery, placement of implants, advanced bone grafting techniques, and full mouth reconstruction. Patients find that having both dentists at the practice lend itself to a comfort to patients knowing that most procedures can be handled at Triple Crown Dentistry, rather than having to be referred out to another office.

Dr. Eric Nunnally


Dr. Eric Nunnally is a Louisville native. In 1999, he received his degree in Dental Laboratory Technology from BCTC, and then went on to earn his bachelor’s degree in 2003 from the University of Kentucky. Dr. Eric Nunnally worked in the dental lab field for years and received his CDT (certification in dental technology) and TE (international technologist certification). After 15 years of working in the laboratory field, he decided to return to school to pursue his love of patient care. He graduated with his doctorate in dental medicine from the University of Louisville.

Dr. Eric Nunnally has a unique skillset, having worked for many years in the laboratory field, before becoming a dentist. He is dedicated to serving his patients with a high level of knowledge about dental prosthetics. He has been published in dental publications dozens of times and serves as a liaison between the dental and dental laboratory industries.

Dr. Eric has a true passion for dental implants, and has received extensive training in the placement and restoring of dental implants. He dedicates himself to providing the top level of implant services from diagnostics to surgery and final prosthetics. He is a fellow of the Midwest Implant Institute and has been invited to train dentists in dental implants internationally. He dedicates a large amount of time every year to education and training to ensure he continues to perform dental implant work at the highest level and uses the absolute best of techniques and equipment.

In his spare time Dr. Eric loves to play golf, cycle, and is a huge fan of UofL sports. Dr. Mary Kathryn and Dr. Eric have been married since 2009 and have two beautiful children, Stone and Scarlett. They are a very active family and love to go on trail walks, traveling, and going to the movies with the kids.

Love these dentists! Super professional, excellent at what they do, and very friendly. The entire office is wonderful.

I highly recommend Triple Crown Dentistry. Their patient staff members worked with my schedule, explained all procedures and costs to me in full detail, helped me utilize my dental insurance correctly and completely restored my faith in my smile. Thank you from the bottom of my heart!

It was my first time visiting this facility. The staff was very welcoming!! Excellent with kids, very informative and took the time to address any questions we had. The office was very clean and provided great information on preventive care. We will definitely be back!

You did a GREAT job! Your office is so pleasant to visit and everyone makes the patient feel welcome. Cannot say enough about you and your staff!! Don't EVER change!! So glad you moved to the neighborhood. Being fairly new to this section of town I had been trying to figure out which dentist I would go to that was close by! Glad I waited until the building was completed and your name went up!! PERFECT!

Thank you is just not enough for all the work you performed on my teeth! Due to your gentle touch and careful work my mouth is pain free! You are such a blessing to me and my family!
