Herbert M. McCollum, DVM

Dr. McCollum completed his pre-veterinary college training and veterinary school at The Ohio State University, graduating in 1970.  He then served two years of active duty, as a captain in the U.S. Army Veterinary Corps receiving awards including the Army Commendation Medal for his service.  Moving to Nashville in 1972, he practiced as an associate veterinarian in a practice in West Nashville before founding Priest Lake Veterinary Clinic in 1974.

While developing the practice into a multi-doctor practice, he was also a founder of the Nashville Pet Emergency Clinic and served in many positions in local and state veterinary organizations. 

Doctor McCollum and his family have had a wide variety of pets over the years and currently share their home with Annie, a Labrador Retriever mix and their farm with three donkeys and two horses.

Kathy, his wife of over 45 years, has played an integral role in the practice from the beginning, and continues to handle many of the administrative tasks.  They have been blessed with four children, who with their spouses have provided fourteen grand children.  The McCollums love family times as well as hiking, gardening, YMCA workouts and actively participating at St. Ignatius Orthodox Church.



Van Pennington, DVM

Ever since Dr. Pennington could remember he wanted to become a Veterinarian. His compassion for healing and helping animals made him realize at the age of 14 that this is what he wanted to do.  He was hired on and worked hard in this same clinic in clean-up for 5 years just to learn anything he could before he entered college.

Dr. Pennington did his undergraduate studies at Vol. State Community College and at U.T. Martin and graduated from the University of Tennessee's Veterinary program.

After college Dr. Pennington returned to Priest Lake Veterinary Hospital and is now a clinic owner along with Dr. McCollum.

Dr. Pennington treats all types of pets- he has a special interest in exotic species, and currently owns a number of exotic pets personally, such as reptiles, birds, and pocket pets.

He and his wife have 2 sons who love pets as much as their parents!
