Ronda Stryker lives in Portland, Michigan and has three children with her husband, William Johnston. The Stryker siblings made their fortune off the back of the work of their grandfather, Homer Stryker, who founded Stryker Corporation to sell his innovative medical inventions.


Ronda Stryker’s grandfather Homer Stryker (Full name Homer Hartman Stryker) was a medical doctor specialising in orthopaedics. He was born in 1894 in Wakeshma Township, Michigan and served in World War I as an infantryman, returning home after serving in France.

Qualifying initially as a teacher, Stryker worked several teaching jobs in Michigan to pay for his tuition, working to put himself through medical school. He earned his doctorate of medicine from Michigan University medical school in 1925. After graduating, Stryker interned in the University Hospital before starting his own medical practice in Kalamazoo, Michigan.

In 1935, Homer Stryker began developing his innovative inventions, including a hospital bed that helped prevent bedsores, and the now world renowned “Stryker Saw” – used for cutting bone and plaster casts.

In 1946, he founded Stryker Corporation (initially named the Orthopaedic Frame Company before being renamed Stryker Corporation in 1964.

Eventually, Homer Stryker retired from practising medicine to focus solely on developing Stryker Corp with his son, Lee Stryker.

Ronda’s Parents Lee and Betty Stryker moved to Kalamazoo to be near to Lee’s father Homer and his growing business. In 1969 Lee Stryker was made president of Stryker Corp and under his stewardship the value of the company grew exponentially.

Lee and Betty Stryker settled in Kalamazoo with their daughter Ronda, and had two more children. They lived nearby to Homer and his wife, Mary Jane, and to the Stryker business.

At that time, Stryker was still very much a family business. In an interview with Michigan Live, Ronda Stryker recalls her mother’s frugality, saying:

“It was the best thing that ever happened to me. You can’t let money define you. You may have it one day and not have it the next.”


In 1976, Ronda Stryker’s parents were tragically killed in a plane crash, shortly after she graduated from University, leaving her ageing grandfather to run the family business alone.
