Founder/CEO, Head of Training, Canine Behavior Expert
Sandy’s work with DASH, its employees, its customers, and the community, taught her the importance of communication when it comes to bringing people together for a common cause. She believes communication is equally important in training dogs. Luckily, Sandy speaks both canine and human!  When a Vizsla rescue named Brooklyn came into Sandy’s life and home many years ago, it set in motion her journey to becoming one of the area’s top positive trainers. Brooklyn was two years old and spent most of her life in an outdoor kennel. She had no prior training, no enrichment, and no socialization. Sandy knew she would need some professional help training this dog, who was pretty much out of control. Sandy sought the help of one of the few trainers around at the time, who, as she learned, used harsh training methods. Following her instincts, she knew there was a better way and discovered the world of positive training at a camp up in Vermont, which was just beginning to take hold in the dog training industry. She was hooked! For the next 23 years, Sandy has attended Camp Gone to the Dogs, learning from some of the pioneers and leaders of the positive training movement, including Patty Ruzzo, Leslie Nelson, Sue Sternberg, and others.
After training Brooklyn using positive methods, she moved on to helping others do the same. Sandy developed the only dog training group class program offered through the City of Alexandria Recreation Department and conducted private lessons in people’s homes on weekends and evenings. Through mostly word of mouth, more and more people began contacting her for help in training their dogs. DASH and DOGS have been Sandy’s two passions for a long time. In 2017, she retired from DASH to realize her dream of opening the Wholistic Hound Academy.
Today, Sandy continues her mission of empowering dog owners by teaching them how to communicate with their dogs, how to reinforce the behaviors that they want, and how to respond to both their dog’s good and the bad behaviors. Her goal is to teach people how to train their dogs to make incredibly brilliant choices, so that they can both live better, happier, and easier lives together.
For over 20 years, Sandy has been training dogs using rewards-based, positive reinforcement methods. She is a Certified Professional Dog Trainer (CPDT-KA), a member of the Board of Directors of the Association of Professional Dog Trainers (APDT), a licensed certified Family Paws Parent Educator (FPPE), a member of the Pet Professional Guild (PPG), and on the list of national Truly Dog-Friendly Trainers.
Named one of Alexandria’s Living Legends for her work in developing and leading DASH, the area’s award-winning transit system, Sandy brings this same commitment and devotion to her clients at Wholistic Hound Academy. While all good trainers love working with dogs, the best trainers have the people skills necessary to work with humans.

Christine Yeannakis, CPDT-KA

Senior Trainer
Chris’ interest in dog training began in early 2010 when she adopted two young adult rescued dogs. Both needed training and help with behavior challenges. After lots of reading, viewing videos and volunteering for Homeward Trails Animal Rescue, Chris decided she wanted to become a certified dog trainer. In January 2014, she entered the apprentice trainer program at a local training center. Many hours of seminars, studying and observing later, Chris was hired as an assistant trainer. In the fall of 2017 she became a Certified Professional Dog Trainer-Knowledge Assessed (CPDT-KA).
After several years as a lead trainer with the organization where she trained, Chris became the “resident” trainer at a dog daycare facility.  During the quarantine, Chris taught private lessons on her front lawn.
In June 2021, Chris joined the Wholistic Hound Academy staff. Recently, she successfully completed a service dog coach training program and is now a Certified Service Dog Coach.

Nina Tingley, CPDT-KA

Born and raised in Stuttgart, Germany Nina grew up with a family dog since the age of 12.
In 2014, her and her husband adopted a one year old German Shepard-Collie Mix named Mickey, who had prior lived on the streets of  Romania. Overwhelmed by all the triggers in Mickey’s new environment, his behavioral challenges soon made it necessary for Nina to reach out to the helping hands of a dog trainer.

As the positive reinforcement training progressed, it was incredible to see the changes in a dog who had to learn from scratch how to function in “the real world”.

The vision of helping other dogs to be at their best and assisting fellow dog owners to make this beautiful connection with their canine companions sparked the idea in Nina to become a dog trainer.
In 2016 Nina, husband Jim and Mickey moved to Alexandria, Virginia and it wasn’t until then,  she followed her calling.
She became a volunteer at Animal Welfare League of Alexandria (AWLA) where she soon joined the “Behavior and Training” team and to this day works with dogs that show high arousal, or shy and fearful behavior.
Through a fellow volunteer Nina found her way to Wholistic Hound Academy (WHA) in July 2020 where she became part of the apprentice program.

Thanks to the experience and knowledge gained at WHA she managed to achieve professional certification by the Certification Council for Professional Dog Trainers (CCPDT) in April 2021.

Christopher Fedorchak, CPDT-KA

Christopher is a Certified Professional Dog Trainer, Knowledge-Assessed (CPDT-KA), a Pat Miller Certified Trainer (PMCT-1), and is currently pursuing a Master's Degree in Applied Animal Behavior and Welfare at Virginia Tech. Christopher's first experience with animal behavior came when studying Biology at the College of William & Mary. After a short detour into the practice of law, he moved to Virginia and began volunteering in various roles for local animal rescues, including fostering dogs. He rediscovered a passion for animal training after adopting a fearful stray hound in 2017. Struggling with the behavioral challenges of his new dog, he reached out to one of the rescues for referrals to local trainers and behaviorists and assembled a wonderful team that guided him in making the world less scary for his hound. Amazed by the positive change in his dog, he was reminded of his earlier interest in animal behavior and set out to learn about current science-based training methods and how to apply that knowledge in everyday life with companion animals. 
Christopher spends his free time studying, hiking, and pursuing Nose Work with his foxhound, George.

Paul Johns, Ph.D., CPDT-KA

Growing up, Paul enjoyed playing with his friends' and neighbors' dogs but wasn't able to have his own dog until later in life. On February 14, 2020, Paul drove to Stuart, VA to pick up his first dog: a 10-week-old border collie puppy named Ria. Some people would think that getting a highly intelligent and energetic border collie puppy would be a bit of a challenge for an apartment-dwelling, single, first-time dog-owning, working professional—and they'd be right!
But having made new scientific discoveries while obtaining a Ph.D. in Physical Chemistry from the University of Notre Dame, Paul was used to tackling challenges. His educational background provided him with an ability to quickly and independently learn and acquire new knowledge and skills and teach those skills to others. He quickly became immersed in the world of dog training, learning as much as he could as fast as he could so that he could face these new challenges head-on. He is also starting to train his dog to compete in agility. Paul believes that learning concepts through games can inspire a dog to make great choices, build relationships, and transform a dog's struggles into its strengths. Games-based training avoids the use of force, intimidation, or deprivation.
Paul is an Absolute Dogs Training Academy and Agility Academy member. He hopes to join the Absolute Dogs Pro Dog Trainer program the next time registration is available.

Christine Tschech

Agility Instructor
Christine started agility with her Labrador Brownie - the family pet - 10 years ago and she is now competing with her two Border Collie boys, Jack and Kwik. Christine’s dogs have several MACHS and have made Finals and Podiums many times at Regionals and Nationals. They compete mostly in AKC, UKI and ISC. Christine believes working small skills and concepts will lay the foundation for success later on and that keeping training fun for dogs and leaving them wanting more is just as important! Christine truly loves teaching and tries to instill joy and confidence in the teams working with her. She feels that “if agility isn’t fun then we’re not doing it right!” :)

Zoe Philippides

Nosework Instructor
Zoe's first experience with dogs began when she was just two years old and her parents brought home an Irish Red and White Setter puppy. She helped raise her family's Golden Retriever and second Irish Red and White Setter, and in 2017, Zoe bought her first dog. She now competes in nosework at the Elite level and in lure coursing with her five-year-old Pharaoh Hound. 
Zoe has a significant background in education, teaching everything from math at Mathnasium to environmental justice during undergrad, to legal writing at The George Washington Law School, where she attends law school full time. She feels happiest when she is teaching others, so it made sense to marry interests and help others learn about the amazing sport of canine nosework.
