She also likes to workout and go shopping. Johnna has been in the medical field for almost 10 years and thoroughly enjoys helping people. She started her career by working for a Durable Medical Equipment company promoting respiratory equipment. She quickly learned the importance of obstructive sleep apnea and how it affected people’s lives in a significant way. In addition, she was drawn to the fact that a lot of patients struggled with using their CPAP/BIPAP machines. Later, she began to work for an in home sleep study company and began to work heavily with both doctors and dentists. She worked with many dentists and enjoyed teaching them how to screen their patients for sleep apnea, order sleep studies, and treat them with a dental device. This eventually led her to meet Dr. John Bigler and start working at Oral Sleep Medicine of Arizona. She was able to educate doctors, cardiologists, pulmonologists and so forth and help them understand the dental device. Johnna truly takes pleasure in working with both medical offices as well as the patients in aiding them through the process of getting their appliance.
