Our People
  • Shawn DeRemer, MD President, Founder
    Shawn DeRemer, MD

    Ever wonder why AANW has such a vibrant culture of customer service excellence? It all starts with Dr. Shawn DeRemer. He’s the charismatic leader, the hard-working, passionate champion people want to follow. He grew up with a “work hard, play hard” mentality, values which have helped him build an organization that’s less about corporate rhetoric and more about the AANW family. His entrepreneurial spirit guides AANW as it grows and expands from a powerful Pacific Northwest anesthesia force into a strong national presence.

  • Gregg White, CRNA CEO, Co-Founder
    Gregg White, CRNA

    Before he entered the anesthesia field, Gregg White was a successful entrepreneur. His experience as a hands-on leader and a savvy businessman gives him the unique perspective of both medicine and the bottom line. He began his career in anesthesia as a Certified Registered Nurse Anesthetist in a busy trauma center where, over the course of several years, he’ll tell you he learned the business end of anesthesia in “the school of hard knocks”. Growing up on a horse ranch in Western Oregon, he’s still an avid outdoorsman. He says he’s a fisherman who happens to love math, running, and spending time on the golf course. He’s busy saving so his kids will have a college education, but jokes, “As soon as they are all educated, I’m going fishing!”

    As the daughter of a doctor and a teacher, it’s no surprise that Molly is a giver; her heart for service is evident in everything she does. As the head of HR and compliance, she minds the company’s regulatory Ps and Qs and oversees credentialing and onboarding of new staff. Molly says her degree in biology taught her how much small things matter. She says “no job is too big or too small for me,” and believes in giving her all because “you might as well get it done and do it right!” She’s a traveler, a world-class gift giver, dog lover, and enjoys frequent science pub lectures. She thinks it’s amazing what you can learn over a plate of nachos.

Prior to joining AANW, Kelty worked for the State of Oregon and an accounting firm. Growing up on the island of Guam gave her a love for travel and the ocean, and as a kid you could find her stomping around in the jungle, barefoot, building forts and picking coconuts and mangoes.
