Dr. Sarah (Sally) Alexander, DVM
(Surgeon)
Dr. Sally Alexander, our spay/neuter extraordinaire, has been with TSC since the clinic opened in June 2009. Dr. Alexander came to TSC with valuable experience as she was a spay/neuter veterinarian
with the Humane Alliance Clinic of Asheville, NC,
which established the protocol for high-quality, high-volume/low-cost spay & neuter.
As if that weren’t enough, Dr. Alexander was also a trainer/mentor for new clinics following the Humane Alliance way! TSC was extremely fortunate to be able to establish our first clinic with her in Sharon Hill, and bring her to our new location in Collingdale!
Since 2009, Dr. Alexander has put her experience and surgical skills to providing the highest quality spay/neuter services to the cats and dogs that come through the clinic doors as TSC moves forward in our mission of ending the euthanasia of adoptable pets in the Greater Philadelphia area.
​
Dr. Alexander is a 2002 graduate of North Carolina State College of Veterinary Medicine.
She and her husband Will are proud parents to their wildly cool son, Liam
In her free time, she loves listening to music, attending concerts, crocheting, and ALL things horror!
