Celina Schmucker is the Deer Creek’s Office Manager. Celina was raised in Southside and Western Virginia where her love of horses began as a child. She and her husband, John, owned Aspen Hill Quarter Horses, a training and boarding facility of AQHA Show and trail horses located along High Bridge Trail State Park in Rice, VA. They coordinated with numerous professionals over the years to provide training, instruction, shows and clinics to their clients and the community. It was during this time that Aspen Hill became home to the Longwood University Equestrian Dressage team. John and Celina enjoyed sharing Aspen Hill and all they were blessed with.

Celina comes to us with years of business office, equine and veterinary clinic office experience. She has been devoted to horses, their care and the success of those that love them. She now owns a small farm in Dillwyn, VA and enjoys spending time with her family, two horses, Joey and Rylee, and her baby – and Australian Shepherd named “Austin.”



Mickey is our littlest herd member. He came to the clinic in May of 2015 through Powhatan Equine Rescue League as a 1 year old stud colt. The plan was for him to find an adoptive family after he was gelded. However, while he waited for the procedure, Dr Arledge fell in love with him and decided to adopt him herself. Mickey has since settled in and has become the clinic mascot. He   made his first public appearance at the 2015 Powhatan Christmas parade. He always loves to meet new people and enjoys running around & kicking up his hooves.
