Sponsor a Clinic

We need sponsors to keep our clinic fees low.

Without sponsorship, what we must charge to cover our costs ($200,000 annually) is still not affordable to some families. While we have the support of a few amazing animal welfare organizations, we would love to have the support of businesses, citizens, clubs and local government from within the areas we serve.

Call us at 719-581-9285 to discuss!
