Dear Friends and Clients,

As we begin 2021, we are thrilled to announce that Animal Internal Medicine & Specialty Services (AIMSS) is moving to a new state-of-the-art facility at 600 Alabama Street in the Mission District of San Francisco, where our outstanding veterinary doctors, specialists, and staff will continue to provide the highest quality specialty and emergency veterinary care for your beloved cats and dogs. The new 600 Alabama Street AIMSS facility will officially open at 8am on Monday February 15, 2021!

AIMSS was founded in 2011 by Dr. Jill Williamson with two microloans, and today we are proud to be a local San Francisco business that employs many San Franciscans and Bay Area residents with a passion for animal care and welfare.

As the only 24-hour specialty and emergency veterinary care facility in San Francisco, it is critical to AIMSS that San Francisco pet owners can be sure they will receive the highest quality emergency veterinary care for their dogs and cats when they have an emergency in the middle of the night, or after-hours.

Note that AIMSS will be closing the facility at 1333 9th Avenue, effective February 15, 2021, and we are moving our entire dedicated staff, business and operations to the new state-of-the-art facility at 600 Alabama Street, San Francisco

AIMSS and its dedicated veterinary team look forward to continuing to provide the highest quality care and specialty surgical services to you and to our thousands of customers and their dogs and cats in this new location for years to come.
