MEET THE TEAM
Bio: Alex’s work is grounded in over five years of hands-on experience, ongoing study, and a ongoing passion for canine behavior. He specializes in behavior modification and building functional obedience that fits into real life.
Before opening up Riverview Bark and transitioning to this field full-time, he worked in a fast-paced corporate world, where he developed a strong foundation in leadership and communication. That experience taught him how to break down complex concepts, meet people where they are, and build trust - skills that now play a central role in his coaching style.
Alex’s approach is straightforward, honest, and centered on what will actually move the needle for you and your dog. His philosophy is simple: real progress starts with the human. When owners feel confident and consistent in their guidance, dogs naturally follow. Every program is tailored to the unique dog-and-owner team, with a focus on trust, structure, and clear communication to create meaningful, lasting change.
Training Philosophy: Lead with empathy, guide with structure. Behavior change starts with trust—and ends with empowerment on both ends of the leash.
Pack Member: Proud dog dad to Jodie (English Staffy).
