Behavior Team of the Bay Area, CA

Erika Liljefelt

Certified Trainer & Behavior Consultant, Accredited Dynamic Dog Practitioner, Certified Separation Anxiety Pro Behavior Consultant

Erika is a force-free, multi-certified dog professional who takes a holistic approach when working with dogs and their guardians. She believes in taking a bottom-up approach to look a little deeper at why a dog might be behaving in a particular way.

As an Accredited Dynamic Dog Practitioner, she specializes in assessing dogs to identify potential physical discomfort that may be contributing to behavioral issues. Because a subtle shift in behavior may signify that a dog is experiencing a high level of pain, she believes that it is important to assess a dog with behavioral issues for potential discomfort prior to starting any type of training program.

Erika is committed to always putting kindness to dogs and their guardians first and foremost. She is a proud member of the Pet Professional Guild, Project tRade, and the Shock-Free Coalition.

Mary Kniskern, Fear-Free Certified, KPA-CTP

Professional Dog Groomer

I began my career as a kennel tech and service dog trainer in 2006. In 2011, I began my career in pet grooming. I was unhappy with the treatment I saw in various grooming salons I was employed in. I opened my own salon in 2016 and built my business on the promise that I would never put any dog through what I wouldn’t put my own dog through. I graduated from the Karen Pryor Academy in 2022 and have been Fear-Free Certified Professional since 2021. I use my skills as a positive reinforcement trainer in the grooming salon to ensure every dog in my care learns to trust me and the grooming.

Suzi Moore, LVT, CPDT-KA, CBCC-KA

Cat Behavior Consultant

Suzi Moore is a licensed veterinary technician and certified behavior consultant with 35+ years of professional experience and a special focus on cat behavior issues. She sees cases virtually since her physical presence most often alters the cat’s behavior and focus—she doesn’t need to see the problem in action to fix it! She starts her virtual consultation with a tour of your home so she can see where the cat’s resources are and where the problem is happening. She then creates a custom behavior plan for your unique situation, using only positive, non-punishment methods. By sharing her screen, she can show you various example videos of other clients working through diverse solutions so you’ll see exactly what YOU will be doing with your cat(s). You then receive an abundance of support as you and Suzi implement your plan.
