4 Paws Leadership Team

Mark Thomas

In 2018, Mark began volunteering at 4Paws for Ability and was immediately drawn to its mission and the people who accomplish it, and of course the dogs. He volunteered in many ways, but felt a calling to use his experience to help 4 Paws with the campus development, demolition and building remodeling.

Mark brings tremendous experience to his role at 4 Paws. He is a retired Fire Chief from Beavercreek Township Fire Department after a lifetime of service as a first responder. He has a wide variety of safety certifications and has served as a fire safety educator at Sinclair Community College, and has also obtained a commercial real estate license. He shares his wealth of knowledge with 4 Paws as our campus expansion project manager, having served in the same capacity for multiple municipal building projects.

In March 2019, Mark was appointed to the 4 Paws Board of Directors and managed the campus development and construction of future training buildings. in June 2021, Mark accepted the role of Executive Director and his background has been critical as 4 Paws moves forward to the future. Mark lives in Beavercreek with his wife, Betsy, and their Fabulous Flunky, Talbott.

Brian Arney

He loved how much of a positive impact a service dog could make in a child’s or veteran’s life. Having years of experience volunteering at SICSA, a local shelter that promotes the welfare and adoption of companion animals, Brian thought 4 Paws for Ability would be an exciting opportunity and was hired as a Kennel Manager in November 2012. Brian assumed the role of Operations Director in 2015.

Erin is a Dayton, Ohio, native who fell in love with 4 Paws as a volunteer trainer during her college years. Instead of following a career path with her history degree, she joined the 4 Paws team immediately after graduation. Erin oversees the 4 Paws breeding program, which ensures our future service dogs have the health and temperament necessary to be successful when placed with a client family. Her in-depth knowledge of the dogs in the program aids her when evaluating dogs for our advanced training program. As a result, a high percentage of our dogs are successfully placed as task-trained service animals.

Peg Walsh Bernert
Training Director, 4 Paws Alaska

Peg Walsh Bernert has had a lifetime passion for all things pertaining to dogs, but it wasn’t until her 3-year-old autistic son Leo was lost and presumed drowned that she entered the service dog world.

That day, after her son was found safe and her heart had recovered, she realized that a trained dog could have tracked her son.

That’s the day she found 4 Paws for Ability. Since receiving her son’s service dog in 2007 Peg has been affiliated with 4 Paws as a client, foster puppy parent, and finally completed a training internship at 4 Paws in August of 2011. She lives in Anchorage, Alaska with her husband Dave, son Leo and, of course, many dogs.
