Logan Portillo
Logan’s love for dogs started early. He grew up surrounded by them, thanks to his aunt who bred American Bulldogs. He always knew he wanted to work with dogs in some way.
Born in Mexico and raised in Tucson, Arizona (fluent in Spanish), Logan took an internship at a veterinary clinic where he gained hands-on experience with hundreds of dogs.

About LOGAN
Who is Logan Portillo?
After a few years, Logan decided it was time for a change and relocated to Denver, Colorado. He then spent three years focused on boundary training and studying animal behavior, eventually leading a team of technicians and helping to train over 800 dogs.
Along the way, Logan discovered a passion for obedience training and began to share his skills with friends and family in need of help with their dogs.
When it came time to turn that passion into a career, Sit Happens was the obvious choice. Our team’s commitment to living beyond the leash resonated with Logan, and he knew it was the perfect place to continue his journey as a trainer.
