If Dr. Arie Dosoretz had a life motto, it might be this: There has to be a better way.

That’s been the way he’s approached the business of medicine going back to when he was the rare physician-in-training, at the University of Pennsylvania, who earned a dual M.D./MBA degree. “There weren’t a lot of physicians in business school,” Dosoretz says, adding he wanted to be a doctor who also understood the financial side of health care. 

Dr. Arie Dosoretz helped launch Advocate Radiation Oncology late last year.

The "better way" philosophy manifested itself in graduate school at Penn, when Dosoretz watched four of his classmates launch online eyeglasses company Warby Parker, which has since grown into a billion dollar brand. Even though Dosoretz says he “was as surprised as anyone else” Warby Parker disrupted the eyeglasses business, the success he saw firsthand cemented his belief in finding a better way. “I get really passionate about creating things,” he says.

That led Dosoretz, in late 2019, to be a founding partner in Advocate Radiation Oncology, what’s now the only locally owned and operated radiation oncology practice in Southwest Florida. There are three Advocate locations, one each in Port Charlotte, Fort Myers and Cape Coral.   

Dosoretz and some of his fellow Advocate co-founders started the practice after working at Fort Myers-based 21st Century Oncology. Dosoretz’s father, Dr. Daniel Dosoretz, helped build Fort Myers-based 21st Century Oncology into one of the largest cancer services entities in Florida in the 2000s. The company, under his leadership, grew from less than $60 million in revenue in 2000 to $737 million in 2013. An Australian health care giant, GenesisCare, acquired 21st Century earlier this year.  

In starting a new practice during a period of consolidation, particularly in cancer care, Dosoretz says he believes there’s a way to utilize an economy of scale model without diluting patient care. “There is real demand for high-level cancer services in Southwest Florida,” Dosoretz said in a June interview. “While that sounds simple, it’s actually quite disruptive.”  

Dosoretz says the better way at Advocate is a model that could be replicated in other markets, but he’s watchful to not grow too fast, too soon. “I don’t want to dilute our culture or our quality,” he says.

He adds he would never expand at the expense of patients —  the driving force behind his better way mission. “I’m inspired and motivated by our patients,” Dosoretz says, “people who are sometimes fighting through incredibly devastating circumstances.”

Travel somewhere fun with my wife to belatedly celebrate our 10 year wedding anniversary. Also go out to a nice dinner.
