Katie MaclaskeyKatie Stenhouse - Owner

Katie Stenhouse is the owner & trainer of Happy Valley Adventure Boot Camp, & is an avid fitness & nutrition enthusiast.  Her love of sports & the outdoors began on the slopes of Mt. Hood at the tender age of 5, where she was proudly known on the mountain as a “Powder Pig!”  Growing up in Portland, Katie’s love of sports grew to include volleyball, basketball, snowboarding & wakeboarding, all of which she pursued throughout her high school career. 

In search of a new adventure, Katie moved to California at the age of 20 to pursue two of her greatest passions: fitness & fashion.  After managing & owning her own boutique in La Quinta, CA called “Divas of the Desert,” Katie realized that, while she loved fashion, her greatest passion was in fact for fitness & nutrition.  At this point, she became an NFPT (National Federation of Personal Trainers) Certified Personal Trainer, & began training clients at her local gym, where she gained her Gravity Training Certification as well.  In 2009, she started her own successful boot camp on the bay in San Diego, CA. This is when she fell in love with the group fitness concept & training people outside in the fresh air!  Seeing how well her clients responded to the format, she found that everyone LOOKED FORWARD to working out together, making it not just about working out, but about being together & being outside. 

 Moving back to her hometown of Portland in 2011, Katie intends to bring this type of fun, outdoor workout to the women of Lake Oswego with her own Adventure Boot Camp, on the shores of the Willamette River. A year later she moved to the east side to open her Happy Valley location. In addition to being a Certified Personal Trainer, Katie is also a Nutrition Consultant, believing that good nutrition is fundamental to a healthy lifestyle.  Katie is dedicated to continual education in all things health & fitness-related, and brings her unique enthusiasm for this field to her clients with fun, safe, & challenging workouts.  To end in Katie’s own words:  “I can’t wait to meet you & help you  achieve your goals for a fit & healthy lifestyle - this is my passion, & I hope it will become yours too!”
