Gretchen Nahkala, Owner, Instructor, EMT, RDH
Gretchen has been in the health field as a dental hygienist for over 25 years. She became a certified CPR instructor so that she could train her coworkers, but her outgoing personality and knowledge soon put her classes in demand. As a result, she created In A Heartbeat to meet the CPR and First Aid needs of the medical field and other vocations that require safety training. In 2006, she returned to school to become a certified EMT, and currently serves as the Ambulance Director with an on-call fire department. She wears many hats, but her favorite role is that of loving wife and mother. Her husband Jeff continues to support all that she does while her kids keep her laughing.
