Here are a few of our instructors — this page is a work in progress, more biographies and photos to come.

Mary Flood

Mary Flood is renowned in dressage circles for her FEI level success as a competitor and trainer of scores of successful dressage horses and riders, but to Tri-State, she is a voice of reason to a group of enthusiastic equestrians, many with little or no formal dressage show experience.

In addition to her long list of accolades in the saddle, which include numerous USDF Horse of the Year Awards from second level to Grand Prix, Mary, a USDF Certified National Level Instructor, is adept at breaking down the complicated and the sophisticated for novice level consumption.  She will get to the root cause of issues and provide exercises to help riders help their horses find balance and progress.

For over five years, Mary has generously provided regularly scheduled group and semi-private lessons, generally twice weekly, woven in among her full training business at her expansive Wildfire Farm in Lovettsville.  Her facility provides both indoor and outdoor riding arenas, facilitating all year lesson opportunities.  Mary has also participated as an instructor in Tri-State’s adult summer camps, hosted at her farm.


Melissa Hunsberger

Melissa is a Pennsylvania transplant operating as a trainer in the eventing discipline out of Lovettesville VA. She is a Level 3 ICP Instructor, and has been providing regular Tri-State instruction at several venues for many years.  Her teaching style appeals to riders and horses of all personalities and abilities, Melissa is committed to working with each horse and rider as an individual, and structuring a program to help them reach their individual goals, whatever they may be.


Alyssa Peterson

Alyssa is Last Frontier Farm’s Assistant Trainer. She came to Last Frontier Farm in 2011 from Maryland, having successfully competed her own Stormin’s Barbie through the Advanced level and earning Team Silver at the NAJYRC. A truly superb horsewoman, Alyssa is an “A” Rated Pony Clubber and retrains Off-the-Track Thoroughbreds and also breeds her own. She competes Last Frontier Farm’s young and sale horses along with her homebred Stormin’ Truth and R Perfect Storm. She is a fabulous teacher and patient rider, and we all appreciate her never-ending patience and kindness!

Charlie Wacker

Charli Wacker is a local horse trainer and riding instructor specializing in western riding and horsemanship. Her love for horses began at an early age and since her first pony, Charli has set her goals to understanding and bettering the human and horse relationship.  Charli has provided Tri-State western riding lessons and has given several cow clinics to Tri-State members.  Tri-State’s mechanical cow resides at Ride On Ranch and is used in many of the club’s lessons/clinics.

Ride On Ranch offers equine assisted Hippotherapy and Charli manages the herd of therapy horses and facilitates the day to day operations.


Sharon White

Sharon White, an established advanced level event rider, operates out of her Last Frontier Farm in Berryville, VA.  Sharon, and members of her team, have been providing dressage, stadium and cross-country lessons to Tri-State members for over a decade.   Also, Sharon has generously provided several weeks of adult summer camp for Tri-State riders.

Sharon is known for her absolute dedication to her horses, her students, and Last Frontier Farm. Sharon credits her success as a rider to the years of quality training she received from the best international event riders in the world. These include Bruce and Buck Davidson, whom she worked for at their Chesterland Farm, Torrance Watkins, for whom she worked while obtaining her degree, and Mary Flood who steadfastly built the foundation Sharon needed to succeed. More recently the coaching of the inimitable Jimmy Wofford and Jules Nyssen has been instrumental in giving Sharon a competitive edge.
