  • At APMSC, we offer all of the medical, diagnostic, surgical and dental care services your animal family member needs to enjoy a long, happy and healthy life. More importantly, we focus on making our patients feel safe and comfortable – whether it’s an extra belly rub, some special play time or bribery by way of treats – so that they not only feel relaxed during their visit, but they actually enjoy being here! Most of the time they never even know they’re being examined or treated! Whether you recently moved to the Diamond Bar or Walnut area, or you’ve been here all your life, we invite you to come by and see what a difference our Skillful & Knowledgeable Caring®  makes. We’d love to welcome you and all of your animal friends to become a part of the All Pets family.
