owner and integrative health coach
Dr. Holly Peng
I believe the foundation of "being the best version of you" and "living life to its fullest" is having HEALTH. And health is not the absence of disease but an optimal state of mental, physical and spiritual well being. I believe that everybody in this world can tap into that deserved authentic health and there is nothing more important.
Growing up with my grandmother (who lived until she was 105) I would hear her mantra in my ears -"watch over your health- without it, nothing else matters". All the money in the world would be useless without your health. Without your health, you cannot be en effective parent, worker, or leader.
I believe furthermore that we were put on this earth to experience an exuberant life and the power to attain it is inside each one of us.
Here at Island Trek Fitness, we are dedicated to helping you achieve this exuberant life."
Dr. Peng is the founder, owner, and manager of Island Trek. With a 22-year career in clinical medicine, she has worked for several institutions such as Group Health and Kaiser Permanente. As a self-employed contract/llocums physician, she brings a wealth of experience and expertise to the fitness retreat. Hailing from Tucson, Arizona, Holly pursued her undergraduate degree at the University of Chicago and obtained her medical degree from the University of Arizona School of Medicine. She completed her residency in family medicine at the University of Washington and Group Health, becoming board certified in the field. Additionally, Dr. Peng holds a diploma in tropical medicine and disease from the London School of Tropical Medicine and Hygiene.

yoga instructor, hiking guide
"I believe everyone should be able to access yoga and fitness no matter their ethnicity, gender, orientation, religion, or body type. I am creating a baseline of mindfulness in everything that the people I teach and work with do. People should feel strong in their beautiful bodies and that the work first starts inside the mind, not what the number is on the scale".

Andreas, a Pacific Northwest native, has dedicated the past 13 years of his culinary journey to Seattle, Anacortes, and currently Kitsap County. In 2013, he pursued his passion for the culinary arts at the esteemed Seattle Central Culinary Academy. Since then, Andreas has actively sought inspiration by collaborating with renowned chefs, constantly enriching his repertoire.
His culinary style is a delightful fusion, drawing influence from his immersive experiences at local gems like Atown Bistro, the enticing Hawaiian-inspired fried chicken haven of Maono Fried Chicken and Whiskey, and the worldly delights of Tallulahs, among others. These distinctive culinary environments have shaped Andreas' unique approach to food, resulting in a harmonious blend of flavors and techniques.
During his leisure hours, you'll often find Andreas tending to his thriving vegetable garden, where his bountiful produce is always shared generously with others.
