Lisa Martin,

Jumping Clinician 
Lisa is a 25 year old horse professional, who loves being in the horse world, not only as a hobby, but as a profession she truly loves. She started riding at the age of 10 and knew this was what she wanted to do with her life. Soon after, she began working in the industry and riding with several hunter / jumper instructors in and around Brewster, NY. In 2015 she was offered a position in NJ as the assistant manager / trainer at an eventing facility. There she taught lessons from beginners to 3'. She also rode with Jane Cory and discovered her love for eventing. She has competed successfully through novice level eventing and schooled training level. When she wasn't competing at one-day horse trials, she was attending jumper shows and clinics with top event riders such as Marilyn Payne. Lisa is now

working at Avalon Farm, where she has developed a strong dressage foundation, riding with top trainer Heather Mason and Jannike Gray. This all around education makes Lisa the perfect jumping clinician for us at Sonnenhof!

Kirsten Gray, Owner & Head Trainer

Kirsten is the backbone to this program and you will see her out and about everyday at the farm.  She was born and raised near Hamburg/Germany and came to the States in 1992.  Her experience with horses reaches back to her cousin Bernd breeding Hanoverians and putting her on a horse as a 5 year old - from there, it was no turning back....

Kirsten has successfully imported a variety of horses, holds her German FN Bronze Driving Certification, German Trainer Certification for the Disabled, USDF Bronze and Silver medals and the ASFA Pilates Certification. She also organized many clinics with top German  and local trainers.

Kirsten has competed her Friesian gelding, Jannus, at third level and is bringing up more horses every year. She is currentle showing her Andalusian mare Ravenna at 3rd Level, and Jannike Gray's Lusitano stallion  Teimir at Inter 1.  In 2017 she won the First Level East Coast Pony Cup on Anke Ott's 'Legolas', whom she worked with for only 16 months.

Being interested in the 'less-than-perfect' horse, she believes strongly that Dressage is FOR the horse, and that we learn from and about each of them. 

Since 2012 Kirsten trains consistently with David Collins and lately rode in clinics with Laura Graves, Heather Mason, Felicitas von Neumann-Cosel and Frank Henning, Mastermind of the "Old Masters" Clinic Series. Among others, she has trained with Sabine Schut-Kerry in 2006/2007, Lendon Gray and Fie Studnitz Andersen.

Aside from her German FN Bronze Driving Certification and her German Trainer Certification for the Disabled, Kirsten holds her USDF Bronze and Silver  Medals and strongly believes in education on and off the horse in order to give her students the best lesson experience and knowledge possible.

Rafael is our barn and farm manager. He has established a great routine to keep the horses healthy and happy, help clients and keep the grounds groomed and paddocks clean.

Our horses adore him, and he always stops and checks on everyone during the day, even if they just need a pet or scratch. 

Beth Anne Voight-Jause,

Weekend Instructor 
Beth Anne has been riding horses for over 20 years. Starting as a little girl jumping and eventing, but Beth Anne realized that dressage was the discipline she was most passionate about and has since focused her showing and riding on that. She worked at Cricket Hill Farm in Ancramdale, NY for many summers while in school, and rode with them at the Youth Dressage Festival. At Cricket Hill, Beth Anne worked around the farm, exercised horses, and taught children's camps and lessons focusing on developing horsemanship and horse knowledge as well as riding skills. 
A graduate of Fairfield University and Boston College, Beth Anne currently works in Residential Life at Sacred Heart University, and has been riding at Sonnenhof Equestrian Center with Kirsten Gray since she began at Sacred Heart 6 years ago. She is excited to begin teaching again and help riders achieve their goals, create a dynamic and harmonious partnership with their horse, and never lose sight of the joy of riding.
