Our Faculty

Our students are guided by master trainers who are deeply experienced, highly educated, and are endlessly engaged in continuing education in order to maintain our high standards of the most up-to-date instruction. They have worked extensively in shelters and training organizations, run training businesses of their own, and continue to help individual clients and their dogs. This means that you get a real-world education, allowing you to confidently apply your skills after graduation.


Mac has helped thousands of dogs and their people lead happier lives in each other’s company for the last 10+ years as an accomplished trainer and behavior consultant.

While focusing intently on fear and aggression for several years, Mac developed an insatiable passion for prevention. This is currently evidenced in her leadership of SF Puppy Prep, Outdoor Education SF, and Puppy Talk with Mac, training organizations that support puppies in various stages of development.

Mac loves to teach and talk dog. A 2009 honors graduate of the SFSPCA Academy for Dog Trainers, upon graduation Mac immediately returned to coach students in two subsequent cohorts. Concurrently, she volunteered for over 300 hours, training volunteers, teaching classes, and working directly with shelter dogs needing behavioral modification.

Mac’s continuing education has included courses of study with Bob Bailey and Susan Friedman, as well as a litany of multi-day seminars and conferences throughout her years as a professional trainer.

Mac shares her life with Gaby, a 2002 UC Davis Vet Med graduate who has since retired from veterinary practice, and their 4 Greater Swiss Mountain Dogs.

Jennifer Sims

Jen began her animal career in sheltering at Peninsula Humane Society more than 20 years ago.  As Shelter Manager she met thousands of animals learning about dogs and cats as well as pigs, goats, and chickens, and became fascinated with animal health and behavior.

She left PHS and started Busy Pets, a pet care business caring for animals with special health and behavior needs.  But, it wasn’t until an untrained, undersocialized, and fearful Great Dane became a client, and then became her own dog that she developed a passion for positive dog training.  As he grew to 160 pounds she realized that there was no forcing him to do anything he didn’t want to do.  She bought The Culture Clash and After You Get Your Puppy and most important, hired an Academy grad to help.  He became a well-behaved member of the canine community.

Jennifer graduated from Academy for Dog Trainers, indulging herself in six weeks of bliss doing nothing but talking about, learning about, and training dogs, which hooked her on training for good.  She opened Happy Home Dog Training specializing in private training for dog aggression.

Jen started working in shelters again, first at Humane Indiana then PAWS Chicago.  She worked with shy dogs and those with aggression issues and staffed a behavior helpline.

As a people trainer she developed and taught classes about dog behavior evaluations, dog body language, and dog handling to certify volunteers and staff to work with challenging shelter dogs.  She’s also created animal health and dog training protocols and earned a certificate in Workplace Learning and Performance.

Jen became a Certified Behavior Consultant – Canine (CBCC-KA) and has attended multi-day seminars with Ian Dunbar, Susan Friedman, Pat Miller, and graduated from a Wolf Behavior Intensive course.

Jennifer lives with a Cattle Dog mix, a wayward rabbit, and a bunch of foster kittens.

Keshau Henderson

Keshau lives in San Francisco, California where she is the owner of The Mindful Pup Behavior & Training. She has presented seminars and talks on a variety of topics, ranging from reactive dog classes, working with fearful dogs, and force free husbandry training. 

Starting her canine journey a decade ago as a professional dog walker in San Francisco, Keshau’s curiosity and a desire to help the dogs in her walking groups motivated her to further her education and seek certification as a dog trainer and behavior consultant. A DTIA graduate, her passion for learning and expanding her skills continues with the best in the field and she remains committed to continuing her education and professional development.

Amrit Khalsa

Amrit is a San Francisco native who has had the opportunity to work with thousands of young puppies and parents to build a strong foundation for happy lives together.

She holds a BS in Ecology, Behavior, and Evolution and a Minor in Psychology from The University of California at San Diego (2014). Growing up in San Francisco, she began her training and animal education career working with exotic animals.

Starting in 2004, she worked at the San Francisco Zoo, the Suisun Wildlife Rehabilitation Center, the Houston Zoo, and at the Living Coast Discovery Center.  After many years working with exotic animals, in 2015, Amrit turned her attention to training dogs (her favorite learners!) as a puppy counselor with SF Puppy Prep’s Puppy DaySchool.

In 2017, Amrit connected with Mac, graduate of the Jean Donaldson Academy for Dog Trainers and Owner of SF Puppy Prep and Outdoor Education SF. Her extensive mentorship deeply expanded and continues to grow Amrit’s abilities.

Amrit played an instrumental role in the development of the Outdoor Education program, training adolescent dogs and parents all over San Francisco before returning to SF Puppy Prep in a leadership position. She now works as SF Puppy Prep’s Program Director managing dayschool, classes and private training as well as training puppies, parents and staff alike.
