Veterinarians in Skokie


Even after over 40 years of protecting the health of Chicago's cats and dogs (and occasionally when on vacation, wildlife) Dr. J. Thomas Johnson – or "Dr. J" as his clients and colleagues affectionately call him – is as passionate and excited about his profession as he was when he first set his sights on becoming a veterinarian as a child.

A native of Rockford, Illinois, Dr. J attended the University of Illinois and after two years as an undergraduate, was admitted to the University of Illinois College of Veterinary Medicine. He graduated with his Doctorate of Veterinary Medicine in 1968.

After settling in Chicago's suburbs, Dr. Johnson built North Shore Veterinary Clinic in Skokie in 1972. Outside running his new practice, he also attended veterinary seminars and classes and spent time at Purdue University's veterinary school. Long before echocardiograms were available for pets, Dr. J religiously sat in at Cook County Hospital as they began performing these procedures in people. Constantly seeking to expand his knowledge, Dr. J also attended courses and discussions on cardiology at Lutheran General Hospital. He received his certification in Canine and Feline Medicine from the American Board of Veterinary Practitioners (ABVP) in 1980 and in Small Animal Internal Medicine from the American College of Veterinary Internal Medicine (ACVIM) in 1981.

In an effort to share his impressive breadth and depth of knowledge and experience, Dr. J has given lectures at many veterinary associations, including Chicago, Milwaukee, and the Northern Illinois veterinary associations, as well as nationally at the ACVIM convention in Washington DC. He has published several articles in veterinary journals. Dr. J has participated in research projects in cardiology, gastroenterology, arthritis studies, and coagulation testing. Two of the studies were for major pharmaceutical companies and were submitted to the FDA. Dr. J was the first to use calcium channel blockers successfully in dogs and his pioneering treatments are used for many disorders in cats and dogs. He was also one of the first veterinarians to implant a pacemaker into a dog, and his revolutionary work made the local and national news. He has since performed over a dozen implants.

In fall of 2017, Dr. Johnson sold his practice to Companion Animal Hospital Partners as he looks forward to retirement within the coming years. Dr. Johnson and his wife Annette, a retired school teacher, have two grown children, Lindley and Derek, and two Labradors, Raven and Natasha. In his free time, he enjoys being active in his community and his church, playing tennis, and camping in very remote areas.

Vets in Skokie


What is your educational and veterinary medicine background?

I attended St. George's Veterinary School and settled down after graduation in San Francisco. While there, I worked at a 24-hour Emergency Hospital and general practices for the last 12 years.

Why did you decide to become a veterinarian?

Even as a kid, I knew I wanted to work with or be around animals as much as I could. As I evolved into more vet care as a veterinary technician, I then realized I wanted to be even more involved with their wellbeing and health.

What is your most memorable moment as a vet?

Some of my toughest and most memorable cases were dealing with animals that were suffering from 2nd and 3rd-degree burns. Most were from house or apartment fires, and their needs and treatment plans were complex. Helping to get them through their recovery was amazingly fulfilling.

What are the best things you find about being a veterinarian?

Honestly, solving the most complex cases and providing relief to pets and humans alike, during difficult times.

What are your special interests in the field of veterinary medicine?


What is the most unusual pet you have helped treat?

Toss up between an iguana or a horned owl.
