Meet The Team

Karen Stock

Operations Director

Karen originally started out at K9 Top Performance as a client, over 23 years ago, with her first working dog, her German Shepherd Nico. She is our longest continuous client!

After spending 30 plus years in the world of banking and brokerage firms, she decided she needed a change and took early retirement to join our team in May of 2018, and never looked back.

She is now our Operations Director for our parent company, overseeing all of our facilities, as well as the acting General Manager for two of our locations.

Besides keeping the businesses running smoothly and watching your dogs learn and grow, her favorite part of the day is greeting every dog as they come into our facility in the morning, and giving out treats and love before they go home. She believes that all of the dogs that participate in our Daycare, Training, and Boarding programs are an integral part of our Family, and treats/ loves every dog as if they were her own.

Karen is a certified AKC Evaluator for the Canine Good Citizen, AKC Community Canine, AKC Urban Canine Good Citizen, AKC Family Dog Program, and the AKC S.T.A.R. Puppy Program. She would like to eventually become a certified dog behavior consultant.

When she’s not at work, she spends her free time with her Dutch Shepherd, Rambo (a familiar face at K9, as he’s usually keeping an eye on things from our main training floor) and they enjoy hiking, training in different environments, swimming and spending time at their other home near Acadia National Park.

Since then, he has become the Director of our training program for our obedience, behavior modification and protection training programs  Nick believes that training is the start to your best relationship with your dog, and wants all of our clients to have as fun and fulfilling a relationship with their dogs as he does with his own.

Nick is working towards becoming a certified AKC Evaluator for the Canine Good Citizen, AKC Community Canine, AKC Urban Canine Good Citizen, AKC Family Dog Program, and the AKC S.T.A.R.

Carleena Sparrow

Assistant Manager

From a very young age ,Carleena has had a passion for animals and especially for dog training. One day, she found a video on Instagram of a man working his dog, and started following his account. As she watched his videos she learned that the trainer she was watching had originally trained at K9 Top Performance, and her interest in the company grew. She reached out to see if the company was hiring, and started out as a kennel technician.

In a short time, we realized that Carleena was a naturally talented handler and had an aptitude for training, and offered her a training position. Since that time, she has worked with all breeds and ages of dogs, and truly enjoys watching her students grow and progress. She is amazing at educating her clients on training and behaviors and believes  that building a relationship between dogs and their handlers is of utmost importance. 

Carleena is working towards becoming a certified AKC Evaluator for the Canine Good Citizen, AKC Community Canine, AKC Urban Canine Good Citizen, AKC Family Dog Program, and the AKC S.T.A.R. Puppy Program.  When she’s not at work, she enjoys spending time with her personal dog.

Jacob Whiteford

Trainer

Jacob joined the K9 Top Performance family originally when he brought his German Shepherd puppy Bella to Steve Roberts for personal training. While working with and talking to Steve, he  was intrigued by the business and asked if we were hiring, and started working in our daycare. He was very interested in canine behaviors and thought training might be something interesting to try, so after working with Steve for his own dog's training, and spending a couple of years managing our daycare and learning pack behavior, he asked Steve to mentor him.

Since he has been with us, Jacob has worked with puppies, adult dogs , senior dogs, and dogs with behavioral issues. He enjoys working with the dogs and their owners and watching the change in their  relationship as the owner gets more confident in their handling skills. He has also started working as a decoy with our protection and competition dogs as well as working with and decoying for other dog clubs.  Jacob is working towards becoming a certified AKC Evaluator for the Canine Good Citizen, AKC Community Canine, AKC Urban Canine Good Citizen, AKC Family Dog Program, and the AKC S.T.A.R. Puppy Program.

When Jacob isn’t at work, he likes to fish in tournaments, is an avid Baltimore sports teams fan, and  spends his time working with his personal dogs: Sully, Bella and Thor. Jacob is hoping to have his long coat German Shepherd, Sully, ready to compete in Protection Sports this upcoming 2024 season.

Best place ever! They truly treat my dog like one of their own! I live in New Hampshire and drive all the way to Reading because I know I can trust them! Karen at the front has been nothing but helpful and friendly. My Benny was trained by Nick who was extremely patient and took the time to form a bond with us. I would recommend K9 Top Performance to anyone who owns a pooch.

I’ve been professionally training dogs for 20+ years. I have my own training facility in NH but wanted a separate place to come train my Belgian Shepherd in protection - something I don’t specialize in. Despite other options in my area, my criteria for a trainer that was positive, motivating, and good with humans and dogs (especially puppies) was imperative so I was very picky about whom I wanted to work with. I was told about Steve from a client who had also worked with him with her GSD and I decided to call. I am thrilled I did. The staff is incredibly welcoming and full of positive feedback, the dogs are happy, and both my dog and I leave wanting to go back. Thank you to Karen and Steve, you’re stuck with us now.

Allison S.

There are many options for training and daycare facilities in the Reading area and the decision to use K9 top performance was based on the methods they use to train dogs and how they treat them. I have been bringing both my dogs here since the eldest was 6 months old, he’s now almost 4. We over the years have used the K9 camps, both individual and group obedience training, and regularly use the doggie daycare.
