DIANE GIESY
VP of Sales

Diane has lived in western Washington all her life. Her decades in Friday Harbor on San Juan Island will always hold a special place in her heart. She currently resides in Mount Vernon, WA where she has grown to love the beauty of the surrounding farmlands and the ever-changing seasonal vistas. The spring daffodil and tulip fields with their dazzling array of colors are a particular favorite!
Over the years, Diane has been fortunate to experience diverse parts of the world, enjoyed many modes of travel and enjoys flying, boating and long road trips. As a musician herself, she loves listening to and supporting live music.
She welcomed the opportunity to join the Cornerstone Healthcare Training team in 2020. Her passion for making a difference, inspiring people to grow and learn, perfectly align with Cornerstone’s commitment to kindness, compassion, and the best quality training and support available for caregivers.
