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.

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.

“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.

Michele Brown – Dog Trainer

Michele enjoys to work with clients and loves helping people. With Sit Means Sit, she feels that is being fulfilled.

“All of the board and train dogs I have had, I see them gain a great deal of confidence and balance. It is due to the Sit Means Sit dog training system and a trainer who understands dog behavior and knows how to communicate with a dog in a way that they will succeed. That is why I feel I am so well suited for what I do and I am so very thankful to be a trainer for Sit Means Sit. I stay humble but confident in my growth. For once in my life, I actually look forward to the work of the next day and don’t mind working as long as it takes.”

Cody McClosky – Dog Trainer

Cody is a dog trainer that has been training alongside a Master Trainer with more than 10 years of experience. She is very driven and has already helped train more than 50 different dogs with all kinds of aggression and behavioral problems. She said working with Sit Means Sit will provide her with an opportunity to make a difference in the area and save as many dogs as possible.

A girl she went to high school with inspired her to become a dog trainer — the girl had rescued a puppy from the local shelter and over the course of a year, she watched her puppy grow up and become a sweet loving dog. One day, he bit her after she tried to take a toy from him. In the following weeks, the aggression became worse, so she offered to help her and her dog but she had her mind set. The next day, her friend took the dog to be euthanized. Her dog is what drives me to better other people’s dogs, including my own.


Cindy Rohrs – K-9 Evaluator

“I’m a long-time animal lover originally from Wisconsin. Proud mother of three children (1 Navy), a son-in-law (Army), and two beautiful grandchildren. I’m thankful for the opportunity to team up with such a great group of dog trainers to help families build healthy/happy relationships with their dogs.”
