Animals have been a part of my life for as long as I can remember. I grew up surrounded by dogs, cats, and even hamsters, and I spent my summers on my grandmother’s farm in Greece, where I cared for everything from goats and chickens to bunnies and much more . I was always drawn to animals, especially the strays—I would feed them, care for them, and inevitably start training them & when they would have puppies I would place them to their new home.

After a major earthquake in Greece, I witnessed rescue workers using trained dogs to locate survivors. I was captivated by the connection and teamwork between dog and handler, and it sparked a lifelong passion for dog training. I quickly became known in my village as “the dog girl,” often seen with a small pack of strays happily trotting behind me.

In 2019, I got my first dog as an adult and trained her to be my service dog. That experience deepened my love and respect for the bond between humans and their dogs. After helping a friend run her pet care business, I realized it was time to follow my own path—and that’s how my dog training and care journey officially began.

Now, I’m proud to offer compassionate, personalized care and training for dogs of all breeds and backgrounds. Whether it’s walking, boarding, or behavior work, I bring years of hands-on experience, a deep love for animals, and a commitment to helping both dogs and their people live their best lives together.
