Despite Parkinson’s, Greg Climbed One of the Highest Mountains in the US

At the age of 59, with a 27-year history of Parkinson’s disease under his belt, Greg made it to the top; “Dr. Kumar has been so supportive of me reaching this dream that he even said he would climb it with me,” Hatstat explains. Mt. Harvard, near Buena Vista, is a very difficult climb. It’s the third-highest peak in Colorado and the fourth-highest in the contiguous United States, rising 4,400 feet in 6.5 miles to a summit of 14,433 feet.”
