JOLIET — Over the last 56 years, generations of patients have placed their dental health in the hands of Joliet dentist Dr. Thomas Streitz.
For some time, patients have had the option to see the second generation of dentists, Streitz’s son, Dr. Daniel Streitz.
Later this month, they can choose to see Dr. Streitz 3.0 — Daniel’s son, Dan Streitz Jr.
The grandfather, father and son will work together out of their dental office at 1711 Campbell St.
A family affair
In preparation for Dan Jr.’s first day on the job, the office staff discussed how to tell the two Dr. Dans apart — Daniel Sr., 56, of Plainfield, will remain Dr. Dan, while Daniel Jr., 26, may go by Dr. Danny.
“Tom’s little grandson?” said Colleen Reeves of Joliet, one of Thomas’ patients, when she was told he would start work this month. “Danny’s like a little boy to us.”
Danny graduated from dental school at Southern Illinois University this month and is ready to get to work. His brother, David Streitz, 24, is currently in dental school at SIU.
Dentistry is a frequent topic of conversation in the Streitz homes, which contributed to Daniel and Dan Jr.’s interest in the career.
Father taught son, who taught son — and all decided they wanted to work side by side.
The togetherness just makes life better, they say. After a long day at the office, they often go out hunting or fishing together to relax.
“It’s just wonderful. I hunt and fish with Danny and we work together,” said Thomas, 81, a lifelong Joliet resident. “I can’t play golf with him because he’s so much better than me.”
Common bonds
Besides a love of dentistry and a love for the great outdoors, Tom also taught his boys to make their community a better place.
Thomas is not only involved with local organizations such as the Will County Health Department and the Joliet Township High School Board, but has traveled to South America four times to provide dental services.
Both Dan Sr. and Dan Jr. say Thomas has taught them compassion for people. Thomas said they’ve made him a better father.
They all say family is a priority.
“I think that plays a role in why we’re sitting here,” said Dan Sr., who also has a dental office in Plainfield. “We have such a tight family, it has trickled down to our occupation.”
