Tobey Grey Team Leader and Trainer

“Pets can be our friends, our support system, our motivation… our family.”

With today’s busy lifestyles pet owners are often want a life for their animals they simply don’t have the time or energy to execute. Canine Comprehensive was born out of my frustration at how hard it was to give my pets the life I wanted for them, while still balancing my own life.

In my free time, I volunteer with Grateful Dog Rescue fostering dogs who need additional training and performing behavioral assessments for incoming dogs. I also work with MicroMentor helping other small business owners get started. I come from a psychology background and I apply these principles to dogs who have experienced trauma or are coping with aggression.


Carl Fixsen  Assistant 

“I love animals of all shapes and sizes and am excited to get to know each one on a personal level.”

Carl grew up on a farm in Minnesota where he was surrounded by a variety of animals. Carl currently lives with four dogs of his own that he shares with his family! As is a lifetime lover and owner of dogs, he is knowledgeable and has a very gentle, intuitive way with animals. In his spare time, Carl is pursuing a degree in finance or hiking and running with his canine companions.

Joanna Karraker  Assistant 

“As a kid, I raised and trained seeing-eye guide dogs, which gave me a great background in animal care and training.”

Joanna grew up surrounded by German Shepherds, raising many successful working dogs for the blind. In college, she worked at a boarding kennel and from there continued to pursue ways to get her animal fix! After moving to the Bay Area from Pennsylvania, she started volunteering with the Milo Foundation. Neighbors asked her to help with their dogs and she began walking and pet sitting independently and eventually linked up with Canine Comprehensive. 


Leland Wilder  Assistant 

“I’ve been on the client-end of hiring dog walkers and pet sitters in the Bay Area and have clear ideas of what works and what doesn’t when you’re taking care of people’s beloved animals.”

Lee has worked with a large number of trainers and dog schools in the Bay Area for the last 8 years. These have included Bravo Pup, Sirius, Dog Evolve, and SF SPCA puppy training. When he caught the bug for dog training, he took a ton of classes with his dogs learning about everything from puppy socialization, obedience, leash reactivity, tricks, to recall. When Lee isn’t hanging out with clients’ dogs, he shares his life with a very large mutt named Dex. 

Positive Reinforcement

Animals are our companions and our family. I believe in showing them respect and communicating clearly.


I love “problem cases”, aggressive dogs, and special needs pets just as much!
