Of the professional memberships that Rover recognizes on our profiles, does anyone know what APSE stands for?

Thanks! All I was finding was something about sports writers and something about workplace equality, but neither one sounded great. Are you a member of this service? Or are there others you like better? I am gathering information, and am looking for word of mouth yeses and nos.

Right now, I am gathering information, as I am slowly working to become a full time pet sitter, and would like to separate myself from some of the other Rover sitters in my area. I am looking into several professional organization (NAPPS, PSI, Petsit USA) and am wondering which ones are the best.

To be honest I do not like APSE, I think they are relatively new and have a lot to work on. I won't be renewing with them again. I have heard good things about NAPPS and PSI. I have a few certifications under my belt and I am interested in looking into PSI certification program.

Thanks, I thought their site looked a little cluttered or less professional than others and for the price, I could get just as much from one of the other organizations, Word of mouth is super valuable here and I am just looking into my best options to market my business and to be improving.
