Email: RBuchholz@equinepi.com

Dr. Buchholz is from Howell, Michigan and has been around horses for as long as she can remember. She rode a variety of disciplines growing up and showed her horse “Romeo” all-around on the Pinto circuit. She has wanted to become an equine veterinarian since childhood and went to Michigan State University for both her Bachelors in Animal Science and her Doctorate of Veterinary Medicine. During her time at MSU, Rachel worked at McPhail Equine Performance Center, assisting with research in equine back and neck anatomy.

Rachel is thrilled to be joining the staff at Northwest Equine Performance for her veterinary internship. She has always had a devoted interest to equine sports medicine and is excited to gain more experience in advanced diagnostic imaging, lameness evaluation and therapeutic options.

When not at the clinic, Rachel enjoys wine tasting, hiking and trips to the Oregon coast with friends. Her dog “Dempsey” loves Oregon so far, though he is afraid of the ocean waves.

VETERINARY STAFF

Rebeccah Lee, CVT, Veterinary Technician

Email: rebeccah@equinepi.com

At the age of 6 Rebeccah was forced to take horseback riding lessons to help get over a bad equine encounter with a friendly looking but vicious pony.  It took several years of being "stuck" out at the barn with her horse crazy siblings before any interest in horses truly developed. Since then, being around horses quickly turned into a full blown passion. She now enjoys actively riding her two Arabians "Robbie" and "Kastane". In addition to her own horses she also enjoys starting young horses and working with behavior problems in horses. 

Amy Rathburn, Veterinary Assistant

Email: amy@equinepi.com

Ever since Amy can remember she has had a passion for horses. Now that she’s older, she has taken it to the next level and enjoys competing in local hunter/jumper schooling shows. When she’s not in the show ring she very much enjoys helping others cultivate a love and respect for horses through riding lessons. She loves seeing a young horse crazy kid evolve from a shy, timid rider into a confident, skilled, young rider. Although she does love her time teaching people about horses, her heart goes to teaching young horses about people. Molding a young horse’s mind is the highlight of her free time. Although there are many bucks, bolts, and rears, she feels the end result is completely worth it.

Ramiro Chavez

Ramiro has been with NWEP for almost two years, becoming an integral part of our practice both as a veterinary assistant and general maintenance and grounds keeper. He is an avid competitor in calf roping and enjoys training horses for himself and others.

Jon Armstead

Jon has been with NWEP since 2002. John is active in all facets of the practice and has been involved in the horse industry most of his life. Jon has also operated his own horse transport company for over 10 years. Between these two businesses Jon is kept quite busy. However he can still be found riding his motorcycle, or his mountain bike in his spare time.

OFFICE STAFF

Email: HollieB@equinepi.com

As a young girl, Hollie was raised on a farm in Sisters, OR.  She enjoyed spending all her time with her 2 sisters.  They enjoyed riding their horses, chasing chickens and exploring and playing in the big barns.  She later found her interest to be working with children.  She received her Associates in Early Childhood Education and worked with children in the Elem. and Jr. High School setting for the past 15 years. 

She was given the opportunity to make a career change and manage an office environment. She found it to be enjoyable and became her new passion.  Being at NWEP gives her opportunity to do what she enjoys best and rekindles fond memories of her childhood living in the country. 

At home, she is happily married and has 2 daughters.  She lives for being a Mom, from soccer games to dance recital, not to mention all the shopping trips.  Hollie enjoys family and friend time.
