Ayana Jones Tribune Staff Writer Sep 18, 2017
Dr. Orville R. Walls Jr., an accomplished veterinarian and owner of Greene Street Animal Clinic, died on Wednesday, Sept. 6, 2017, at his home. He was 76.
He was born on July 13, 1941 to the late Dr. Orville R. Walls and Thelma Bracy Walls in Kennett Square. He graduated in 1959 from Kennett Consolidated School in Kennett Square.
Walls continued his family legacy by attending Lincoln University and joining Phi Beta Sigma Fraternity, Inc. in 1962, where he was pinned by his father to signify him “crossing over.”
During his time at Lincoln, he began dating Yvette Sills, who became his wife on July 28, 1962. He graduated from Lincoln University, in 1963, with his bachelor’s degree in chemistry and biology.
From 1963 to 1965, Walls worked in the anatomy lab at Einstein Hospital Southern Division, where he conducted cancer research. He began working on his master’s degree in biomedical engineering, with an emphasis on cancer research at Drexel University, when it was recommended that he apply to veterinary school at Tuskegee Institute in Montgomery, Ala. Upon graduation, in 1969, he received his degrees in agriculture and a doctor of veterinary medicine. During his time at Tuskegee, Walls worked in the bacteriology lab and conducted cardiac research at Moton Field due to his knowledge of radio isotopes. He also completed an internship in Poteau, Okla. at the LeFlore County Veterinary Hospital.
Following graduation, Walls moved back to Philadelphia, with his wife and newborn son, in 1969. Upon his return, he became one of three Black veterinarians in the entire state of Pennsylvania. To establish his professional name and build his career, Walls actively worked with the SPCA, the 4H Club, and the Buffalo Soldiers.
Walls also held numerous jobs simultaneously, which included working at Bustleton Avenue Animal Hospital, O’Neal Animal Hospital, Morris Animal Refuge and ChelWayne Animal Hospital. He was known to make house calls 24 hours a day, which he continued to do throughout his career to the sick, elderly, and shut-in. Walls also provided home services for those who were associated with Women Against Rape as well as those who were afflicted with the AIDS virus.
In 1976, he opened the Greene Street Animal Clinic, which continues to be a staple in the Germantown section of Philadelphia. Walls spent his career as a general practitioner treating large, small, and exotic animals including but not limited to mountain lions, chimpanzees, snakes, skunks, cows, horses, dogs and cats.
He was one of two veterinarians to work with the Police K-9 Unit. In 1986, Walls began to focus solely on treating companion animals such as cats and dogs.
Walls was licensed to practice in Alabama, Oklahoma, Delaware and Pennsylvania. He has received numerous accolades and awards throughout his illustrious career, and spent many hours mentoring developing veterinarians. Walls continued to practice and consult until his final days.
Walls lived his life dedicated to God. He actively incorporated the tenants of Phi Beta Sigma Fraternity, Inc. and promoted “brotherhood, scholarship and service.” He was an active member of the community and jokingly referred to by many as “the Mayor of Germantown.”
Walls was a friend, mentor, role model, and veterinarian to numerous individuals around the world.
“He positively impacted people’s lives by the work that he did and by being the person that he was,” his family said in a tribute.
“Orville was the embodiment of love, laughter, commitment, generosity and dedication.”
He loved animals, cars, food, traveling and his family.
In addition to his wife, he is survived by: his children, attorney Orville R. Walls III, Dr. Kathleen E. Walls and Dr. Brian K. Walls and other relatives and friends.
Services will be held Sept. 22 at 7:30 p.m. at Greene Street Friends School, 5511 Greene St.
