Adam Gray


Adam Gray began his riding career at the age of seven.  He trained with various trainers in his hometown of Rochester, New York.  He competed in everything from the Children's Hunters to the Pre-Green Hunters to the Amateur Jumpers, earning multiple championships and reserve championships.


In 1998 Adam became a professional member of the O.P.H.A. and USEF.  During his 30 year riding career he has had many accomplishments.

In 1996 and 1998 he represented Lake Erie College in the I.H.S.A. (Intercollegiate Horse Show Association) National Champion competitions where he helped his team earn 5th place in the nation.  While at Lake Erie College, Adam earned his Bachelor of Science degree in Equine Studies.  Throughout his I.H.S.A. career he was President of the team for 3 years and Champion High Point Rider for many shows.


In 1997 Adam and his horse, A Shot In The Dark, became the O.P.H.A.'s Amateur Jumper Reserve Champion.  In 1999 he became the Director of the Lesson Program and Resident Trainer at a large show barn in the Cleveland area.  Many of his students went on to earn O.P.H.A. and National Year-End Championships and awards.  There, he taught over 150 students per week and attended countless horse shows, both locally and out of state in Pennsylvania, Michigan, Kentucky, and Florida.

In 2001 it was time to move on and go out on his own.  With pride, he introduced Graystone to the hunter/jumper community.  Since the opening of Graystone he had brought many horses and riders through the ranks and has produced many competitive horses and riders.  He has gentle and patient techniques and trains everything from Modified Jumpers to Pre-Green Hunters to Short Stirrup ponies to Baby/Very Green Hunters.  From 2003 to 2015 Adam and his clients have enjoyed much success in the show ring on the "A" circuit and have earned many O.P.H.A and W.Pa.P.H.A. year-end awards.


Liz Mueller


Liz grew up in Illinois where she started riding at the age of 7.  Liz was introduced into the hunter/jumper show world at the age of 8.  Equitation was her specialty, where she went on to win many awards and qualified for Equitation Finals.


From 1990-1997 Liz picked up the art of training ponies and started Eventing.  In 1990 she joined Pony Club where she was given many opportunities to meet and ride with some of the top riders in the country.  Breaking ponies and Eventing was an experience that taught patience and the true art of "staying on."  When Liz was done Eventing she found herself back in the hunter/jumper ring.


From 2000-2002 Liz moved to Vermont to train with a notable dressage trainer.  Liz started teaching lessons while working long hours learning how to manage and equine facility.  In 2002 she became assistant manager for a hunter/jumper facility while critiquing her dressage and going to hunter/jumper shows.


In 2003 Liz moved back to Illinois and continued to ride and train some hunter/jumper horses.  That is where she began teaching her specialty, Equitation.


Liz attended Lake Erie College where she met Adam Gray.  In 2005 she joined up with him to become part of Graystone Hunters/Jumpers where she is currently helping manage the business, teaching lessons, and training ponies and horses.  Liz is proud to be a part of the Graystone family!
