Meet The Dentist


Brady Keller

Hello, I am Dr. Brady Keller. I moved to Billings, MT in July of 2010 after having purchased Dr. Thomas Wickliffe’s pediatric dental practice. I completed my undergraduate training at Brigham Young University in Provo, UT and then received my dental degree from Case School of Dental Medicine in Cleveland, OH. My pediatric dental training was performed at Primary Children’s Medical Center in Salt Lake City, UT.  I am board certified in pediatric dentistry and have been practicing pediatric dentistry for over 14 years–all here in Billings. My wife Jaime and I have been married since August 2000 and have 8 amazing children.  I feel grateful and very blessed to have ended up in such a wonderful community and am excited to see where the future will lead my family and this amazing dental practice.


Clint Chlarson

I am Dr. Clint Chlarson. I have been living in the Midwest for the last 6 years receiving my dental training and look forward to being around mountains again and working with the great team at Rimrock Pediatric Dentistry. I completed my undergraduate training at Southern Utah University. I then went on to receive my dental degree at The University of Oklahoma Health Science Center in Oklahoma City. My pediatric dental residency was completed at the NYU Lutheran Medical Center in Springfield, MO. I have been married to my wife Laci since 2006. We have three (soon to be four) children. We like to spend time outdoors, travel, and hang with the family. I love kids and love to make their experience at the dentist a great experience. I get excited seeing the same kids come back for appointments and do better and better each time. I look forward to serving the little ones at RPD and helping them achieve a healthy smile.


Nathan Stanley

Hello guys, I am Dr. Nathan Stanley. I have been married to my lovely wife Catie Stanley for 12 years and we have three rugrats of our own at home. I attended BYU for my bachelor’s degree in Food Science. I went on to continue my education by obtaining my dental degree from Indiana School of Dentistry. I then spent 2 years as a general dentist, during which, I cultivated my love for treating pediatric patients. I went on to do a pediatric residency through NYU-Langone, and shortly afterwards became a board certified pediatric diplomate. I have never regretted moving to Billings and love all the outdoors which includes fishing and hunting. I am delighted to be part of this community and provide dental needs to its children. I love what I do and working with your kiddos is the bees knees.


Krystal Kazemba

Krystal Kazemba was born in Oconomowoc, Wisconsin, and lived in Wisconsin until the middle of third grade. After leaving Wisconsin, she moved with her mom, brother, and stepdad to Gainesville, Florida where she spent the remainder of her youth. As a child all the way through her time as a high school student, Krystal was a competitive swimmer, helping lead her team to a state championship during her Sophomore year of high school.

After growing up in the “Gator Nation”, Krystal was proud and excited to attend the University of Florida while obtaining her B.S. degree in microbiology and further earning an M.S. degree in Forensic DNA and Serology.

 During the time she was working toward her Master’s degree Krystal was employed as a dental assistant at the University of Florida Pediatric Dental Residency, where she truly learned the value of helping children. It is here where the foundation was laid for her love of Pediatric Dentistry. After receiving her second degree from the University of Florida, she was accepted into LECOM School of Dental Medicine. After receiving her dental degree, Krystal continued her training and received her certificate in Pediatric Dentistry from NYU Langone Health in Holyoke, MA.

Krystal loves the outdoors, sunshine, and friendly people. She has a dog and a loving husband who are her partners in crime and are the first to volunteer to accompany her on any adventure. She believes that you can learn something from everyone and knows not to judge a book by its cover. Above all, she is eager to see what life has in store for her.


Scott Randall

Dr. Scott Randall grew up in the hot sunny desert of Mesa Arizona. After completing his undergraduate degree from Brigham Young University, he attended Western University of Dental Medicine and graduated in 2014. He was awarded the HPSP Health Professions Scholarship for the Navy and went on to serve in the United States Navy as a general dentist. After completing a one year General Practice Residency with the Navy in San Diego, he moved to Atsugi Japan and provided dental care to military families for three years. During this time he deployed on the USS Ronald Reagan and was able to experience life as a dentist aboard an aircraft carrier for four months. After living abroad in Japan, he was stationed in Oahu Hawaii where he provided dental care to members of the United States Marine Corps for 2 years.

Although Dr. Randall loved working with the military, his heart was set on Pediatrics. He was accepted to the NYU Langone Pediatric Residency in Phoenix, AZ and was excited to finally be “going home”. After completing a two year residency in Pediatric Dentistry in Arizona, he quickly realized that his heart no longer belonged to the desert… the Montana mountains were calling his name.

Dr. Randall believes it is very important for all children to have access to the quality dental care they need and enjoys sharing his knowledge with patients and parents alike. His main goal as a pediatric dentist is to have a shared vision with parents regarding treatment options for their child and also provide an experience and atmosphere that the child enjoys!

When not in the office, Dr. Randall enjoys spending time with his wife and three children! Sports are a passion of his and he loves coaching his kids sports and cheering on his favorite sports teams. He loves being active outside, enjoying many outdoor hobbies such as hiking, camping, snowboarding, and fitness training, making Montana a perfect final home for him and his family.
