A doctor whose clients included many celebrities has been identified as the hiker who died last weekend of a heart attack while at a Los Angeles park.  

Jay Goldberg, 53, worked at Cedar-Sinai's Beverly Hills facility as a specialist in obstetrics and gynecology, Fox Los Angeles reported. He was found after the Los Angeles Fire Department was called on May 29 to Will Rogers State Park for a hiker rescue. 

Two rescuers were lowered and found Goldberg dead, the report said.

Many of his famous clients took to social media to express their condolences after hearing of his passing.
