Meet The Off Leash K9 Team

Matthew Sulhoff - Head Trainer

Matthew Sulhoff is the Head Trainer for OLK9 St Louis. He was raised in the Lindbergh South County District, after graduating high school he joined the Navy. After serving his country, he used his military training to become a chef, and he eventually moved back to Missouri.

His interest in animal training is a result of being raised by a mother who often fostered animals and volunteered at shelters. Matthew attended the Tom Rose school and has spent time independently training service animals for disabled veterans. In addition, he has trained police dogs for several officers in the Missouri and Illinois areas. From there, he furthered his education in canine training by attending Off Leash K9. Matthew loves watching the dogs he trains transform into respectable canine citizens, and looks forward to the opportunity to do the same with your furry friend!

Brody Hassel - Trainer

Brody Hassel graduated from Culver-Stockton College, where he received a BA in Communications. A college athlete turned personal trainer, Brody grew up with personal dogs and hunting dogs and always had a history of rescuing dogs and bringing them home to mom.

During Covid, Brody found Raya, his 1-year-old brindle hound mix, and as he spent more and more time training her and taking her on camping and backpacking trips, he grew fond of the process. He then found Off Leash K9 Training to take his training to new heights and has been with OLK9 since!
