The Plucky Puppy Team

Marley Muffin-Face is the original plucky puppy. Katrin adopted him from the San Diego Animal Shelter when he was a puppy. Without many new or positive experiences during his critical socialization period, he was terrified of everything, especially people. As he was getting used to his new family and environment, Marley showed remarkable strength and courage. With lots of remedial socialization, training, and behavior modification, he eventually adapted to his new home and feline and avian companions. He went on to have a distinguished career as puppy socializer and training assistant to Katrin. He passed away from old age and a life well lived at the ripe old age of 16, and continues to be the inspiration for our work.

Plucky Puppy was founded for dogs like Marley, whose spirit could not be vanquished by a bad start in life, and for all the lucky puppies that got everything they needed right from the beginning. We believe that a committed owner—along with ample socialization and effective training—can bring out the plucky puppy in any dog.

Angela Grey, CPDT-KA is a Certified Professional Dog Trainer, lifelong dog lover, and puppy enthusiast. From a very young age she knew she wanted to work with animals, but it wasn’t until her beloved Pit Bull, Bones, entered her life that she realized her truest passion was training. Currently a student of The Academy for Dog Trainers, Angela is committed to force-free dog training that is both easy to understand and enjoyable for dog and owner alike. She especially enjoys working with new puppy owners to get training and socialization started on the right foot. Angela lives in SE Portland with her partner, their three dogs, Bones, Klayton, and Mars, and their very patient cat, Garry.

She and her husband Anrey have one human baby, Charlie, and two small canine companions, Cocoa and Ashe.


Joanna Meleiro, CTC unexpectedly found her calling while photographing adoptable dogs for local rescues several years ago. She became fascinated by the process of making the dogs feel comfortable and happy in front of the camera so their personalities could shine for potential future families. After adopting one of her models, complete with a long list of behavior challenges, she dove into the science of animal learning and quickly changed her career plans. She graduated with honors from the Academy For Dog Trainers and enjoys working with fearful and worried dogs.


Lorena Jasis-Wallace is originally from Kentucky and grew up on a petting zoo and farm, complete with all sorts of creatures- from llamas and camels, to foxes and coatimundis. But dogs were always her favorite. She has a BA from Portland State, and is fascinated by the behavior of both animals and humans. From wilderness leadership to public schools to residential psychiatric, and now to Plucky Puppy, she is excited to help dog parents build lasting and wonderful relationships with their furry friends. Her approach to dog training (and people training!) is based on shaping personality concepts and life skills, with emphasis on fun, optimism, and play. A student of the AbsoluteDogs Training Academy, Lorena is particularly interested in finding creative and stress-free solutions to challenging behavior problems. She lives in SE Portland with her two dogs, two snakes, and an ancient cockatiel.
