In 2007, we opened Lake Harriet Veterinary after extensively remodeling a former daycare center slated for tear down. The original staff of 5 employees has grown to a healthy group of about 30, and a second story was put on the clinic in 2014.

We love serving the wonderful pet owners of the Twin Cities—the privilege of experiencing the bonds between you and your pets nourishes our soul!
