Dr. Rachel Gottlieb
Dr. Rachel Gottlieb creates lasting relationships with her clients and patients, built on a foundation of compassion and confidence. She is trusted by the industry’s top equine professionals and veterinarians for her judgment and reliability. She found a true professional partner in Dr. Mark Revenaugh when she interned with his practice, sharing his passion for seeing patients compete successfully and clients achieve their goals.
A native of Cleveland, Ohio, she began riding and caring for horses at age four and never wavered from her childhood dream of becoming an equine veterinarian. She developed an early interest in equine lameness and diagnostic imaging under the tutelage of one of the world's pioneers in diagnostic ultrasound, “Doc” Ron Genovese. She graduated with honors in animal science from the University of Massachusetts, received her Doctor of Veterinary Medicine degree from the University of California-Davis, where she was also selected for the prestigious Large Animal Ultrasound Fellowship (one of two such training programs in the nation).
As the only fellowship trained ultrasonographer in the Pacific Northwest, Dr. Gottlieb consults on complex lameness cases, and teaches veterinarians nationally and internationally on the use of ultrasound in diagnosis and in rehabilitative therapies.
Dr. Gottlieb frequently travels to horse shows to provide point-of-care service when the stakes are high. She was an Associate Team Veterinarian for the US Eventing Team, performing ultrasound examinations on all team horses as a part of the selection criteria for the 2014 World Equestrian Games. She served as Team Veterinarian for the USEA Area VII Young Riders Eventing Team. Dr. Gottlieb is currently on the board of the National Alliance of Equine Practitioners (NAEP). She also served as President of the Northwest Equine Practitioners Association (NEPA) and was a reviewer for the AAEP Scientific Review Committee. Dr. Gottlieb enjoys teaching and has been honored to speak on numerous occasions for both client and veterinarian education events.
Dr. Gottlieb actively rides and competes in dressage with her Dutch Warmblood mare, Justice. In 2024, they earned the USDF championship for region 6 adult amateurs at first level and were ranked 4th in the nation! Dr. Gottlieb also enjoys exploring the local food scene with her husband Daniel, and daughters Lilly and Devyn.
Dr. Mark Revenaugh
Dr. Mark Revenaugh is the owner of NWEP. He is a renowned expert in the diagnosis and treatment of lameness and performance issues, attracting clients from all over the northwest. His fascination with equine medicine and competitive performance began long before opening his specialty clinic in the Oregon.
Though he studied riding under eventing icon Bruce Davidson, and spent several years in human medical research, his passion was always focused on helping owners and horses maximize their performance potential.
He pursued that passion at the University of Illinois College of Veterinary Medicine, graduating in 1991. Dr. Revenaugh worked with some of the leading sport horse veterinarians in the world, including Dr. Kent Allen, Dr. Haynes Stevens, and Dr. Brendon Furlong. During this time, Dr. Revenaugh authored the first license for use of scintigraphy (bone scan) in the state of New Jersey in 1996. In 1997, Dr. Revenaugh took his first trip as official USET Team Veterinarian, traveling to Germany for a pairs Driving World Championship. Dr. Revenaugh has been honored to serve as a Team Veterinarian or Assistant Team Veterinarian since that time. Duties have included selecting, treating and advising elite level professionals in the equine industry, maintaining health and maximizing performance.
Dr. Revenaugh moved to the Pacific Northwest in 2002 where he intended to create a small and unique practice to work exclusively with equine performance issues and lameness. The clinic quickly grew into one of the premier equine sports medicine practices in the western United States reflecting Dr. Revenaugh's investment in advanced technologies, imaging modalities, and leading edge therapies. Dr. Revenaugh has also served as the Director of Ignite for Equine Athletes (formerly High Performance Sports Group) since 2013 in an effort to help further not only the sport, but the profession as well.
His greatest professional joy remains being part of a winning team; helping horses and owners make good decisions to advance equine health and maximize performance.
Dr. Revenaugh lives on a farm in Mulino with his wife and 2 children. They enjoy outdoor activities including bicycling, camping, and exploring this beautiful region.
Staff
Sierra Parshall
Sierra was essentially raised in a barn in Monroe, WA, surrounded by horses. Her mother specialized in barn maintenance and management, working closely with trainers, and was actually bumped by a horse while pregnant with Sierra, precipitating Sierra’s birth just hours later!
That’s how Sierra explains her passion for sport horses, first competing in eventing and then dressage.
Currently, she owns, cares for and competes in dressage with her thoroughbred cross, Dallan, and earned her silver medal in 2024.
She worked as an equine veterinary assistant for several years before joining the team at Seattle Equine Performance, where she now splits her time between the office doing administrative work and the barns serving horses and owners she has come to know and love.
Hollie Beck
Hollie was raised on a farm in Sisters, OR, where she loved riding horses with her two sisters, chasing chickens and exploring the big barns.
Ultimately, her love for adventure and learning led her to pursue a degree in early childhood education. For more than 15 years, she worked with children in elementary and middle schools.
She was drawn “back to the barn” by the chance to manage the office at NWEP, rekindling fond memories of her childhood living in the country.
She is happily married and has two daughters. She lives for being a Mom, from soccer games to dance recitals (not to mention all the shopping trips).
Haleigh Cepurno
Haleigh grew up in Sandy, OR, in a family of people and pets, including a backyard horse that her parents bought for her when she was a little girl.
She competed in Western cutting and still enjoys riding, but is now focused on showing her award-winning German Shorthaired Pointer named Arrow, who has earned Senior and Master titles in dock diving.
Haleigh worked for five years in a small animal veterinary practice before pursuing her passion in the equine world, joining the team at NWEP.
When not in the office, Haleigh enjoys camping, hunting and keeping her yard beautiful with her three dogs (Arrow, Goose & Diesel) and three cats.
