Our Team

Erik Marksberry DDS

Dr Erik believes we must take our patients’ concerns to heart, and we should approach each appointment as if we were treating a member of our own family. Our only measures of success are the comfort, satisfaction, and appreciation of our patients.

Dr Erik attended the University of Iowa for 9 years and graduated in 1999. He lived in 7 different states growing up, with the longest stay in Dallas, Texas for 8 years.

Dr Erik enjoys race car driving and has driven at Road America, Laguna Seca Raceway, BIR, and the Mid America Motorplex. His favorite vacation spot is Napa Valley and his favorite vacation companion is his wife Krista.

Kayla Libby DDS

Dr. Libby approaches all patients by the Golden Rule; treat them as you would like to be treated. She graduated with distinction from the University of Minnesota School of Dentistry, and was one of four students recognized for their excellence with the Quality Care Given in a Caring Manner award. Dr. Libby not only seeks to provide compassionate care, but to also stay abreast of the latest and most beneficial technologies available.

Dr. Libby can usually be found enjoying the great Minnesota outdoors. She also puts family first, spending time with her and her husband’s family nearly every weekend. She enjoys all Minnesota sports, particularly the Wild, Twins, and Vikings. Unfortunately, her husband Ryan is a Detroit Tigers and Detroit Lions fan, but no one’s perfect, right?
