Mary Marquis, Partners and Events Coordinator

What Mary lacks in horse knowledge, she makes up for in her ability to organize and manage events. With 20+ years of experience in the hospitality industry, including 8 seasons as the event coordinator at a local golf resort, she brings passion, creativity, and experience to Pegasus. When not working, Mary’s hobbies include her family including her 4 children, cooking, traveling, wine tasting and moonlighting at local eateries.

Amy Stoothoff, Program Coordinator

Amy fell in love with animals early on, especially horses. In junior high, she took hunter jumper lessons from Liz Lawrence and spent almost every waking moment at her barn. When she moved to Indonesia in 2001, she lost her horse connection for a while. Later she studied Biology at Biola University and CWU and learned to take care of all kinds of critters. When some health issues came up, she moved home to Yakima. Since then, she’s worked mostly retail, which taught her how to find common ground with anyone. “The Christmas rushes taught me to keep calm despite the chaos and focus on what’s right in front of me.”  Amy started off as a volunteer at Pegasus, and we are so excited to now have her as part of the team!

Heather Born, PATH Certified Therapeutic Riding Instructor, ESMHL Certified

Heather was born in MN, where her love of horses was ignited as her mom was a horse trainer. She was raised in Vancouver, WA area and connected with horses however she could. After high school she completed a 2 year Christian equestrian college in Silverton, OR and received a Certificate of Completion in Equine Studies as well as Instructor Certification through CHA. During this time, she also interned with a hunter/jumper trainer, worked with an equine veterinarian, and volunteered at Forward Stride Therapeutic Riding, where she was introduced to PATH. In 2010, she received her certification as a Registered Instructor and has been teaching ever since. Heather says,” Teaching therapeutic riding lessons is a combination of two of my passions: teaching people and working with horses. Personal experience and observation have made me a true believer in the therapeutic benefits of our relationship with horses.”

Karrie Myre, PATH Certified Therapeutic Riding Instructor

Karrie first became certified in October of 2008 and has been teaching lessons at Pegasus on and off since.  She also holds a Bachelor of Science degree from CWU in Exercise Science and enjoys numerous outdoor activities, including horses, running, skiing, and water sports. Her lifelong love of horses began in a small town on the Washington coast (Westport) where she started riding horses at the age of 10.  She was active in horse 4-H and open shows and enjoyed showing Arabian horses both Western and English.   She became interested in Pegasus due to her love of horses, which lead to her love of the program, its mission, and of course the riders.

Michelle Koffler, Barn Manager

Michelle Koffler, born and raised in the Yakima Valley, now resides in West Valley with her family and horses.  She has lived and breathed horses for as long as she can remember, from the moment she took the reins of her own Shetland pony as a toddler. She spent her own childhood and teen years relishing every opportunity to be in the saddle both for fun and competition. Now she and her daughters show their Arabian and Half-Arabian horses together in both Hunt Seat and Western Divisions.  In 2013 Michelle became involved with the Pegasus Project as a volunteer and has never looked back. Now as a staff member, caring for our herd and seeing first hand on a daily basis the impact these special horses have on the lives they touch is just her favorite thing.  Her experiences have led to a firm belief that horses respond to and show you who you are, how you feel, what you think, and the impact of what you do.  They are here to enable you to learn how to be a better version of you, that is a blessing and something she loves being a part of.
