Mary Cella is a lifelong dog lover based in Bed-Stuy Brooklyn who has been working with dogs professionally since 2017. She’s a graduate of Tufts University and before working with dogs, she was a television news producer who covered animal rights issues (and true crime, back when it was still trashy). She’s a Certified Professional Dog Trainer-Knowledge Assessed (CPDT-KA), is an American Kennel Club Canine Good Citizen Evaluator, and graduated from the International School for Certified Dog Trainers as a Certified Dog Trainer - Comprehension (CDT-C). She’s committed to using only science-based positive reinforcement methods and is passionate about teaching clients how to train their dogs without the use of force or aversive methods of any kind. She specializes in working with young dogs, from brand-new puppies to rebellious teenagers. She’s available for private training sessions in Brooklyn, lower Manhattan and Southwestern Queens.

P.S. That’s her dog Bear. Yes, he is really cute.

  • "Mary is fantastic. Hands down. She has become a vital support for my pup and I as we go through our journey today. She helps him feel at ease and cared for while also teaching him how to be comfortable in the world. I am so grateful to have Mary in our lives! Couldn't imagine our weeks without her."

  • “We love Mary! She. is. a. dog whisperer. I say this most sincerely and with the deepest depths of gratitude and joy! Our dogs are super anxious and hate other dogs, kids, some humans lol but they both love it when we say ‘ready to see mary?!’ Their ears perk up. She’s calming, attentive, generous and discerning. Don’t hesitate to entrust Mary with your special fur babies! she’s the B E S T!!!”
