Dr. Robbie Keels

As an undergraduate at Gardner-Webb University, what started as a summer medical mission trip to Honduras, through God’s very hand and comedic timing, a medical team who never showed, a group of dental students with welcoming arms and many many prayers, a passion for dentistry was ignited. After graduation, Dr. Keels attended the Medical University of South Carolina, receiving his Doctorate in Dental Medicine in 2006, along with the Award of Excellence in General Dentistry. Dr. Keels returned to his hometown to join and help continue to build one of the leading dental practices in the Upstate. At only 34 years old, Dr. Keels was named one of Greenville Magazine’s “Best and Brightest.”
Those weeks in Honduras translated into what has become his overarching philosophy in dentistry, “Always deliver the highest quality of dental care while forming a life-time relationship with the patient.” This philosophy is why Dr. Keels spends countless hours staying on the cutting edge of his profession to ensure his patients have only the very best in treatment.
Dr. Keels and his wife Tara have three sons, Austin, Harrison and Asher, and are rooted in the community they serve. Dr. Keels is an active member of Fellowship Greenville Church and Dental Community Fellowship, a chapter of the Christian Medical and Dental Association. Dr. Keels also provides services at the Greenville and Spartanburg Free Clinic offices and services as the official team dentist for Byrnes High School Rebels.
When Dr. Keels is not in the office you’ll find him with his family spending time outdoors, camping, boating and coaching or volunteering with each of his son’s various sports teams…and if it’s Friday, you’ll likely find him on a golf course somewhere.
“Treat others as you want to be treated” is more than a catch phrase, it si the philosophy Dr. Keels lives by.
