David Besseler

Northern California
Certified Behaviorist

David currently runs his own full-time dog walking business, where he works hands-on with dogs of all temperaments and energy levels every day. Through this work, he gained a deep appreciation for canine behavior, communication, and the importance of structure and consistency.

His interest in training grew after working with one of Koru K9’s top trainers to help his own reactive dog, an experience that showed him how powerful the right training approach can be in improving both behavior and quality of life. Inspired by those results, David decided to pursue dog training to help other owners build stronger, clearer relationships with their dogs.

He uses a balanced approach, combining positive reinforcement with fair, appropriate corrections, and focuses on practical, real-world skills that help dogs and humans succeed together.

Becca Contreras

Northern California
Dog BehavioristBalanced School for Dog Trainers

Becca has been training dogs professionally since 2011. During that time, she has made the transition from a purely positive trainer to balanced training, after seeing the limitations of purely positive training, particularly when it comes to behavior modification. Becca managed a successful daycare, and board & training facility in her home town of Chico, CA.

Her experience at this facility allowed her to gain invaluable experience in dog behavior through working with a wide variety of dog breeds in diverse environments. Becca’s own personal dog, Smokey, a German Shepherd mix, proves that, at 12 years young, it’s never too late to train! A year later Becca adopted an Australian Shepherd, named Bentley, who had resource guarding issues as well as reactivity towards people.

We are happy to report that, through balanced training, Bentley is a calm, cool, and collected guy, and is one of our staff dogs used to help other reactive dogs. Becca has continued expanding her training by obtaining her certification through the Balanced School for Dog Trainers.

Jourdan Murphy

Northern California
Dog Behaviorist

Jourdan was born and raised in Santa Cruz County. Her passion and love for dogs started at a very young age. Jourdan has owned high drive, working breeds her entire life, and realized, at a young age, that she had a natural affinity for training. The beginning of Jourdan’s career in canine training started with her seeking a higher level of training for her Australian Cattle Dogs.

She took them to an Obedience & Agility class at a local police K9 training facility. The facility owner had been training dogs fro over 30 years, and immediately identified Jourdan’s potential, and offered Jourdan her first apprenticeship.

Upon completion of this apprenticeship, Jourdan began private lessons, and group classes in obedience, protection, and agility, as well as board and trains for dogs with behavior issues, and for mobility and medical alert service dogs, and puppy raising. Jourdan’s interest for protection training and sports was peaked, and she began attending protection and obedience seminar or workshop she could.

Through these seminars and workshops, Jourdan has trained with some of the best, and most inspiring trainers in the world. She has competed at a national, and International level with her personal Belgian Malinois, and has trained and titled multiple dogs / breeds.

Jourdan who is forever a student of her craft, is happy to pass along her years of experienced, and education to her clients, and is excited to see her client dogs become happy, confident, engaged dogs.

Celeste Schmidt

Northern California
Dog Behaviorist

From the time she was young Celeste always had a deep passion for animals. Learning as much as she could and spending her free time with the family dogs. In her early teens she got her first dog Dakota, who had severe fear aggression towards people, and fear-based reactivity towards other dogs.

She reached out to local trainers to work with him. That turned into Celeste mentoring with those trainers and eventually becoming their assistant trainer. These trainers worked for an animal shelter, and Celeste assisted them in training and rehabilitating the shelter dogs that had behavior issues.

She learned the importance of timing, consistency, and balance, and worked Dakota through his behavior issues. Dakota was such a success story that he became their go-to demo and training dog! Little did Celeste know at that time that she would eventually end up fulfilling her mentors’ role, and become the lead trainer for the shelter.

Celeste was also responsible for evaluating the temperament of all the dogs at the shelter, giving her a tremendous depth of experience in dealing with a wide variety of breeds, temperaments, and behavior issues. In her spare time, she began training Dakota in sport work — successful competing with and titling Dakota.

It was through this process she discovered her passion for German Shepherds, and went on to compete with and title her first GSD, as well as train him up to be her Medical Service Alert Dog. Since that time, she has also gone on to start her own, successful breeding program for German Shepherds as well.

Maddie Galati

Northern California
Dog Trainer & Behaviorist

Maddie has always had a passion for dogs. Aside from growing up with them, as soon as she graduated high school she was volunteering with a local German Shepherd rescue and shadowing a balanced trainer. After that, she began working for a company that did behavior modification and working dogs.

From there, her passion grew for working dogs and she started working with detection canines in the school system and conservation detection canines that detect invasive species. Maddie was a competitor on Americas Top Dog Season 2 and is now working towards PSA (Protection Sport Association) titles with her Malinois.

When Maddie is not working with dogs she enjoys working out, traveling and hiking (dogs are typically still included here though!).

Izzy Gutierrez

Northern California
Dog Trainer & Behaviorist

Izzy has spent her entire lifetime surrounded by animals and was always the resident expert for all family and friends with pet questions. At an early age, Izzy began pet sitting and quickly became comfortable with a plethora of animals and animal husbandry techniques. As she continued to expand her animal care network, she remained close with her two family dogs, Scout and Sequoia.

Although her love for all animals persists, her true passion remains in dog behavior. Izzy began studying her own two German Shepherd’s behavior and researching operant conditioning and classical conditioning. Her German Shepherds sparked an ongoing curiosity obedience training and she was inspired by her dogs’ ever-present drive to learn and engage.

This continued interest in training led her to volunteer countless hours at the Humane Society of Ventura County. Her time working with high risk shelter dogs gave her the opportunity to work hands on with many difficult cases and observe behavioral changes brought on by a highly stressful kennel situation.

Her natural ability to read canine body language made her one of the few volunteers who could handle the more difficult dogs in the shelter. She committed to help as many reactive dogs as she could and make training her career. While seeking a training school, Izzy met Heather, an animal behaviorist with 10 years of experience and a degree in behavior and neuroscience.

Heather recognized Izzy’s natural talent and immediately took her under her wing and into her internship program. Under the guidance of a behaviorist, Izzy practiced training fundamentals with several dogs with varying degrees of reactivity. Over the course of her internship, Izzy worked with several challenging cases of human aggression, dog aggression, fear reactivity, resource guarding and more.

It quickly became clear, training dogs saves lives, and this constantly fuels her passion to learn more and grow as a behaviorist. Izzy continues her education by attending seminars and seeking her perfect working dog companion who will most likely be another German Shepherd. Once she finds her future working dog, Izzy wants to continue to expand her knowledge of the field by competing in PSA, GRC and scent work.

Dog Trainer & BehavioristAKC CGC Evaluator

Kathi has been working with dogs professionally for over 13 years. Her parents allowed her to get her first dog at 14 years old only because she promised to train him. She signed up for obedience classes and overtook it by week 5, helping the other students and becoming the instructor’s assistant.

She started going to client’s homes to teach private lessons when she got her driver’s license at 16 years old, and started teaching group classes for the Auburn parks and recreation department. After a little while, she wanted to do more than obedience and behavior modification, so at 18, she got her first German Shepherd and started dog sports and Search and Rescue.

She has titled several dogs in AKC obedience and rally, National Association of Canine Scent Work, Schutzhund/IPO/IGP, and Working Dogs of America venues, as well as certified in Search and Rescue for live find and human remains detection.
