About Us

Slide HSMO - Since 1870 Serving People and Pets Since 1870

Our Mission

Since 1870, the Humane Society of Missouri has been dedicated to second chances. We provide a safe and caring haven to all animals in need – large and small – that have been abused, neglected or abandoned. Our mission is to end the cycle of abuse and pet overpopulation through our rescue and investigation efforts, spay/neuter programs and educational classes. We are committed to creating lasting relationships between people and animals through our adoption programs. We further support that bond by making available world-class veterinary care, and outstanding pet obedience and behavior programs. The animals thank you for your support.

About Our Locations

Macklind Avenue Headquarters Center in St. Louis City

Opened in 1998, the headquarters of the Humane Society of Missouri resides at 1201 Macklind Avenue in St. Louis, Missouri, across the street from our former residence of nearly 70 years.

Best Buddy Pet Center in Maryland Heights

Attention St. Charles County and North and West St. Louis County residents – we’re closer than you think!

Thanks to a donation by Elizabeth N. Parrish, our county adoption center was built in 1974 in Maryland Heights. Additional funds raised by the Humane Society of Missouri Auxiliary paid for a clinic and laboratory. The building was again expanded in 1981 thanks to another donation from the auxiliary.

In April, 2017, the new Best Buddy Pet Center, located at the intersection of Page Avenue and Schuetz Road, significantly expanded the Humane Society of Missouri’s ability to provide second chances for the thousands of abused, neglected and abandoned animals in the St. Louis area and provide first-class veterinary care to the public.

The Best Buddy Pet Center currently offers:

  • Adoption Center
  • Animal Medical Center of Mid-America, open to the public
  • Integrated Pain Management Center, open to the public
  • Gift Shop

Our Longmeadow Rescue Ranch in Union, Missouri opened in 1988. The horse and farm animal rehabilitation center is situated on 165 acres nestled in a valley surrounded by trees.

Carol Gates Throop Memorial Park

Featuring a fountain, pavilion and lovely gardens, Carol Gates Throop Memorial Park is situated at 1210 Macklind Avenue on the grounds of the former Humane Society of Missouri headquarters, where – from 1929 until 1998 – more than a million homeless pets found a second chance at life.

Volunteer dog walkers take dogs waiting to be adopted to the park for daily sessions in housetraining, socialization and lessons in basic obedience. Since behavior problems are the primary reason pets are relinquished to shelters, daily walks in Throop Park help the newly-adopted stay in their homes.

To honor a loved one with a tribute or memorial in Carol Gates Throop Memorial Park, please visit us online, phone 314.951.1542 or e-mail the development department.
