The short version

Born in Texas, raised in Colorado, Marine Corps at eighteen.

The Marine Corps brought me to San Diego and I never left. I got a business degree afterwards and spent a while doing work I did not care about.

Then I adopted a dog who was tied to a pole at the beach.

He got harder as he got older. Kicked out of multiple daycares. Training facilities would not take his case. The experts all pointed one direction and I was not doing it.

So I learned to train him myself, enrolled at Animal Behavior College, and found the thing I actually wanted to do. That dog is the reason In Line K9 exists, and the reason I take the cases other people pass on.

I refused to allow my dog to be put down and on the verge of giving up I finally decided who better to train him than myself.

Your dog does not need more commands. Your relationship needs better communication.

How I train.

Balanced, which means tools are picked for the dog in front of me rather than ruled in or out by category. Anything I use has to be humane, appropriate for that specific dog, and genuinely useful. If a tool is not right for your dog, I do not use it.

Plenty of trainers here advertise a list of things they will never do. I am not going to pretend a rule written before meeting your dog is the same as judgment. What I will do is explain the whole method before training starts, so you can decide before any money changes hands.

If you want a purely positive only program, I am not the right trainer and I will say so on the call. There are good people in San Diego who do that work.

What I will not do.

No protection work, no bite sport, no service dog tasks. Those deserve specialists, which is not me. My work is behavior: reactivity, aggression, anxiety, obedience, and puppies who should not become any of the above.

What clients say about the person

Calm, non judgmental, and reachable.

What comes up most across the reviews is not only results. It is calm.

From the very first session, Aaron was calm, confident, and incredibly knowledgeable.

He immediately made a stressful situation feel manageable.

Angela Labadie · Google review

He addressed every single concern I had with patience and detail, and he explained his entire training process so clearly.
