Erika D. | Executive Assistant

Erika and Maddie

Erika joined the AADT team in May 2018 and is the first person you'll likely speak with! Erika has been an animal enthusiast since she can remember - growing up with both dogs and cats has shaped her outlook on life and made her a lifelong animal advocate. When she heard through the grapevine that AADT was hiring, she jumped at the opportunity to support a company whose mission of fear-free training was helping keep dogs out of shelters and in happy homes with happy families. An undergraduate of Vanderbilt University and a graduate of NYU, she has a strong background in financial services, customer service, office management and operational expertise. Currently Erika is a proud co-owner of Maddie, an 80-lb black Labrador retriever mix who loves watching TV, car rides, snuggling on the sofa, and keeping a sharp eye out for chipmunks and squirrels. She also recently adopted two rescue kittens, Barnaby and Lucy.

Sammy | K9 Assistant

             Samson was born in 2011 in a shelter and was rescued by Dave and his family in 2012 from another owner. Sammy is a Labrador mix with a wonderful temperament. He loves to play fetch with a tennis ball (or any toy for that matter)! Back home, he earns his keep (food, treats, and bones) by accompanying Dave on training sessions with dogs who are dog aggressive. Sammy is what is known as a 'bulletproof' dog. This is because he is non-reactive, especially in the presence of other dogs whom are struggling with aggression, fear, or anxiety towards other dogs. When called upon, he will therapeutically help rehabilitate any dog in need of help. He is just an overall wonderful and lovable guy!
