Meet Our Team Of Experienced Dog Trainers

Sonny Madsen – Owner/Master Dog Trainer

Madsen is a master certified dog trainer and owner-operator of our Sit Means Sit Dog Training of Northern Virginia franchise. She is also the founder/president of K-9 Caring Angels Therapy and Service Dogs. An award-winning manager and public speaker with an emphasis on sales, training and motivation, she has always felt an internal drive to help people improve their lives.

Madsen started her business in 2012, wherein just three short years, she grew from a start-up to a top 10 franchise out of 130 nationally, most recently achieving #3 in the nation for 2017. During that time, she also founded K-9 Caring Angels — a 501c3 dedicated to providing therapy and service dogs to the community, including our veterans and service personnel. In 2017, she placed the first full-time, live-in firehouse therapy dog with Fairfax County.


Ted Madsen – Owner/Master Dog Trainer

Madsen is a master trainer and co-owner/operator of Sit Means Dog Training. He is also vice president of K-9 Caring Angels Therapy and Service Dogs. Ted joined his wife Sonny in starting K-9 Caring Angels Therapy Dogs to give back to the community, and through the Warrior’s Angels Service Dogs service, he strives to help our soldiers and veterans by donating psychiatric service dogs to those with challenges like PTSD.

Before becoming a dog trainer, Ted worked in the corporate world as an executive in the travel and tourism industry with Hilton, Wyndham and Resort Condominiums International (RCI). He was also a managing partner with Quintessential Consulting Group. It was in 2010 that Sonny came to Ted with the idea of starting a dog training business after meeting with the founder of Sit Means Sit, Fred Hassen, in Las Vegas, Nev. She thought Ted would think it was a crazy idea, but his support and her drive made it happen — the same is true for K-9 Caring Angels.


Angela Moxley – Lead Dog Trainer

Moxley is a natural-born dog trainer who came to Northern Virginia by way of Wisconsin in 2015. Angela works as a professional dog trainer for Sit Means Sit dog training. There, she first trained her own dog, a small Shih Tzu named Avicci, for her daughter. After experiencing the pride of her own dog receiving the Canine Good Citizen Certification from the AKC, she joined the Caring Angel’s therapy team. Using her dog to teach dog safety in elementary schools and making appearances in nursing homes and hospitals, Avicci’s love spread happiness to everyone wherever she went — even other dogs can’t resist her charm!


Joanna Thomas – Lead Dog Trainer

Thomas has had a passion for dogs since childhood, which led to her starting her career working in animal hospitals. There, she gained a lot of knowledge about the health and care of dogs. She has been a long-time handler for Virginia Search and Rescue and she has taken her training and handling skills to the next level with Sit Means Sit of Northern Virginia.

A goal of hers is to get involved with training and producing fully trained Diabetic Alert Dogs.


Samone Puffenbarger – Dog Trainer

Puffenbarger works double duty as both a dog trainer and as office manager. She teaches several regular group classes, tricks classes and beginner agility classes. Samone is certified with AKC to perform S.T.A.R Puppy, CGC, CGCA and UCGC tests for the public.

“I love it when a client has one of those ‘aha’ moments with their dog and they have success with something that they have been working on for a little while. It feels great! I always tell my clients that baby steps are the way we get to great things, so don’t get upset if things don’t happen as quickly as you think it should. Every dog can succeed, we just need to be there to show them the way.”

Goals for the year:

  • Start training dogs a little more outside of group class.
  • Learn more about scent work.
  • Learn more about training a service dog.
  • Advance my knowledge about agility work.
