Garrison Forest School

Meet Our Staff

A team of talented, experienced professionals and dedicated teacher-coaches leads Garrison Forest School’s equestrian program, which includes nationally ranked individuals and teams in riding and polo. From left: Virginia Shriver '06, Riding Instructor; Rick Harris, Director of Riding; Cindy Halle, Polo Coach; Karen Zinkhan, Riding Instructor; Kaycie Campbell, Assistant Polo Coach.

In addition to teaching the skills required to ride and play polo, each member of the team is deeply committed to the teaching of exceptional horsemanship. Working collaboratively with student-athletes, they foster a high level of confidence, competence and character in the ring, paddock or field—qualities which have long distinguished Garrison Forest’s century-old equestrian program.

Cindy Halle, Head Polo Coach

Renowned nationally for her high standards of play, knowledge of polo, horsemanship and commitment to excellence in sportsmanship coaching, Cindy Halle brings exceptional skills to the polo arena as a player, coach, instructor and umpire. Her polo career while a student at University of California-Davis led her to win four women's intercollegiate titles, acquiring a three-handicap in the arena and a two-handicap outdoors. Ms. Halle was head polo coach at GFS from 1986-1997, during which she led the Varsity Team to five Women's National Interscholastic Championship titles. In 1998, Ms. Halle was awarded Polo Magazine’s Coach of the Year Award. After raising her family, she returned to GFS in 2007 and promptly guided the team to national Championship titles in 2009 and in 2011. Ms. Halle also has a large number of junior and adult polo students from the surrounding community and schools who take lessons utilizing the GFS ponies and facilities. She helped establish the 4th and 5th grade Riding and Polo segment as part of the GFS PE curriculum giving all of the girls in those grades the chance to ride and hit a polo ball. In addition to her coaching and teaching, Ms. Halle also cares for and manages the string of 16-20 school-owned polo ponies.

One of only five U.S. Polo Association (USPA) certifiers for the new USPA certified polo instructor program and certified as an USPA umpire, Ms. Halle frequently officiates across the country at the collegiate and club levels and offers national training workshops for umpires and players. She is an active playing member of the Maryland Polo Club. In 2011, she founded the ongoing "Introduction to Horsemanship and Polo" program for GFS’s Middle Grades Partnership (MGP) program, a community outreach program through the Baltimore Community Foundation.

Kaycie Campbell, Assistant Polo Coach

Kaycie Campbell has worked in many areas of the horse industry, from managing a trail riding stable and breeding racehorses to teaching polo. She graduated from Michigan State University with a B.S. in animal science and a concentration in animal industry and minor in agribusiness management. At Michigan State, she was a member of the university’s Polo Club and traveling varsity team and helped to care for the club’s string of ponies. Playing intercollegiate polo gave Ms. Campbell the chance to learn from several players in the Great Lakes area and the opportunity to teach many beginners the sport of polo. Following graduation until her appointment at Garrison Forest in fall 2016, Ms. Campbell worked at a nationally renowned equine embryo transfer facility in Oklahoma where she bred racehorses, assisted with veterinary procedures, managed pregnant mares and delivered foals. While in Oklahoma, she groomed and played polo throughout the Great Plains circuit.
