Theresa Cahill

Head Sitter, Trainer and Walker

I have been growing A 1 Critter Sitters and Training for 28+ years and have never looked back. We have had previous walkers that have outgrown us and retired. So we are looking for others to fill these positions.

I have trained and certified with Animal Behavior College and have received my Dog Trainer Certificate, as well as Cat Trainer Certificate, Dog Groomer Certificate from PENN Foster University.

I have been First Aid and Pet CPR trained as well.
