Meet Max Seifert, CDBC

Behavior Specialist Focused on Aggression

For as long as I can remember, I've wanted to understand animals — not just teach them tricks, but help them behave predictably and safely in the world. My early experience in horse training and dog-assisted therapy gave me a foundation in reading subtle behavioral signals and managing stress responses before they escalate.

But it was behavior rehabilitation that became my focus, especially for dogs whose reactions had real consequences.

I developed our Connection Over Control method to meet these complex cases with structure, clarity, and evidence-based behavior modification.

Cases we specialize in

  • Dogs who have bitten other dogs
  • Dogs owners feared might escalate into a bite
  • Dogs whose reactivity has limited their family's life
  • Dogs who are suffering from severe anxiety

What makes our approach different

Aggressive behavior isn't a nuisance or a funny quirk. It is a risk. That means our work starts with assessment. Every plan is designed around real-world context, thresholds, and proactive management so you can prevent escalation before it happens.

We don't promise magic or guarantees — we promise:

  • Clear understanding of why aggression occurs
  • Tools to manage and reduce risk
  • Practical ways to improve predictability and control
  • Realistic expectations set with you, not for you

You deserve training that respects how serious this is — and how human it feels.

Credentials that matter

Handling aggression cases requires experience, judgment, and commitment to safety. That's what every client interaction centers on.
