Cheri Campbell

Training Director

In 2001, Cheri began her career in the Department of Corrections. Beginning 2005, she became a Narcotics Canine Handler, where her duties included searching cells for narcotics in multiple correctional facilities, as well as inmates, visitors and employees of the Virginia Department of Corrections.

In 2007, Cheri’s experience in dog training strengthened, when her career as a Narcotics Canine Handler Instructor began. She participated in the Narcotics Canine Handler Schools teaching new Handlers and their dogs on how to do searches as well as training the dogs on how to locate Narcotics.

After years of working alongside canine training, Cheri finally joined SDWR, starting off training puppies at the facilities. She described her duties,

“[Training puppies] included Socializing them, teaching them sit, down, stay, come and proper leash walking. I then progressed to delivering the puppies into the homes of our clients. I have been delivering and training Diabetic Alert Dogs, Seizure Response Dogs and Autism Service Dogs. I am currently the Training Director for SDWR. During my time with SDWR I have trained over 300 very successful Service Dogs.”

Cheri has also helped to supply dogs for the local Police Departments as well as USDA.


Phil Farris

Senior Trainer

Phil has been a trainer for over eight years. Phil’s father, grandfather and grandmother were diabetics, so he is familiar with invisible disabilities. He was the District Trainer in Tidewater for PetSmart for 6 years. Phil trained and evaluated other trainers. Phil was introduced to Warren Retrievers through one of our families. Little did he know Riley-Anne was only the first Warren Retriever he would meet.

“I love making life easier for those with Diabetes through training D.A.D.s and their families. All of the staff is very knowledgeable. Trainers make visits to further training of dogs every 90 days and are not relegated to distance. There is no age limit to receive one of our dogs as with most other organizations. Constant contact is kept with our dog owners to ensure they have the assistance they need. Our dogs are guaranteed for 10 years. Great care is taken to make sure our clients receive a healthy dog. There isn’t an organization that cares more about our clients than we do.”




Erin Coulter


Originally from a small town, Punxsutawney, PA… Yep home of the groundhog. I Started Training my own dogs at age 16. I attended the University of Pittsburgh in PA and graduated in 2006 with a Bachelors of Science Degree in Psychology. I worked as a social worker, counselor and career counselor after graduating college. During that time I trained my two dogs, a Rottweiler and a Bullmastiff. Both dogs have obtained their Canine Good Citizenship (CGC) and Therapy Dog International (TDI) Certifications. Also, I performed private obedience training with friends, family and acquaintances. My husband and I moved to Norfolk, VA in summer 2011 for the warmer weather and the beach, of course. Once we moved, I started working at Petsmart as a Pet Trainer for over a year. There I assisted families with basic obedience training as well as assisting several people with training their service dogs. After learning of the opportunity at Service Dogs by Warren Retrievers in 2012, I welcomed the opportunity to train dogs and help families at the same time. I have been working for the organization since November 2012.

“My whole life I have loved dogs and enjoyed training them.  Shortly after I graduated from West Virginia Canine College in 1992,  I started Southwind Dog Training where I did a wide variety of dog training. This includes individual’s pets and dogs that lived in hospitals, hospice facilities and served as private therapy dogs.
Among my many accomplishments in dog training, I founded BARK (Bluegrass Animal Rescue of Kentucky) where I used rescue pets in therapy roles. And as an advocate for therapy dogs, I placed the first classroom dog in the state of Kentucky. I have also worked as a vet tech for many years and spent quite a bit of time at PetSmart as one of their in-house dog trainers.  I believe in the power of training dogs to heal lives and  I look forward to using my knowledge and experience to help you with your Service Dog from SDWR.”
