Johnna received her bachelor’s degree in psychology at Baylor University in Texas. She also minored in pre-med. Her original intention was to become a surgeon, but an encounter as a patient seeing a physician assistant influenced her to seek her master’s degree in Physician Assistant Studies in Lock Haven University in Pennsylvania. During her studies she focused on orthopaedic surgery.
