Attorney to Run Seven Marathons on Seven Continents in Seven Days to Raise Awareness for Crohn’s and Colitis Disease

Jonathan Negretti, principal of Negretti & Associates, will be competing in the 2020 World Marathon Challenge, in which he will be running seven full marathons on seven continents in seven days.

Along the way, Negretti will be raising awareness and funds for Heather’s Mission, a nonprofit organization co-founded by his wife, Giana, to help those suffering from Crohn’s and Colitis Disease. reported that Negretti will be one of 50 race participants, but the only one with a disability — although he doesn’t see his condition as such. Negretti was diagnosed with ulcerative colitis 20 years ago, requiring surgery that removed most of his large intestine. He has lived full-time with an ostomy bag ever since.

“Participating in the World Marathon Challenge is not only an epic personal challenge, but an incredible platform for me to raise awareness for Heather’s Mission,” Negretti told “My hope is to garner enough attention to make a difference in people’s lives and inspire others who are living with an ostomy.”

Negretti’s personal goal is to raise enough funds so that Heather’s Mission can purchase 1,000 Awesome Ollie teddy bears, which are distributed to patients who undergo ostomy surgeries. Negretti will take an Awesome Ollie bear around the globe with him on the World Marathon Challenge.

Races will start on Feb. 6, 2020, on the ice runway of Novolazarevskaya Station, Antarctica. Other marathons are scheduled for Cape Town, South Africa; Perth, Australia; Dubai, United Arab Emirates; Madrid, Spain; Santiago, Chile; and South Beach, Miami.

clayton trovillionOn August 24, 2019, Clayton Trovillion suffered life-threatening injuries as the result of an automobile accident in Arizona. Tragically, he succumbed to his injuries and passed away seven days later.

Clayton was an exceptional young man whom Negretti & Associates had the honor of representing in the aftermath of an earlier automobile accident, which he had in September of 2018. During that time, we really got to know Clayton and were inspired by the kind of person he was.

Clayton was an outstanding brother to his three sisters and son to his parents. He excelled academically, having graduated high school in just three and a half years, then going on to attend Arizona State University for both his undergraduate (B.S. in Finance) and graduate (M.S. in Finance) degrees.

Clayton also served his country and community. He was an Army Reservist, and completed multiple tours of duty overseas, earning countless military honors and decorations. On top of all that, Clayton was also an Arizona-certified EMT, and would often donate blood and plasma to those in need.

Clayton loved Arizona and would often enjoy its beauty while hiking and riding his motorcycle throughout the desert. He often expressed desire to go to law school — a goal that we are sure was only thwarted by his premature passing. We were especially excited to follow Clayton on this journey.

In honor of Clayton’s enthusiasm for legal advocacy and higher education, our firm established the Clayton Trovillion Memorial Scholarship. This annual scholarship will be awarded to a current high school or college student seeking to further his or her education. Clayton would be proud to know that he helped encourage others to pursue their dreams.

Through our new scholarship, we hope to assist students who embody Clayton’s impressive qualities and wish to use their skills to make a difference.

jonathan negretti in arizona foothills magazineNegretti & Associates Principal Jonathan Negretti has been featured as a “Trendsetter to Know” by Arizona Foothills Magazine. The wide-ranging interview touches upon Negretti’s background and inspirations, and also offers a glimpse into his interests beyond the office.

Negretti, who is currently training for the World Marathon Challenge — seven marathons in seven days, on seven continents — wakes at 4:15 a.m. to hit the gym. “I typically put in two hours of mobility, strength, and endurance training each day,” he says. “By 8 a.m., I am answering emails and making phone calls.”

Family fuels his drive to succeed. “The one person who motivates me is my wife,” Negretti says. “She has no quit in her. She works out all the time. She has excelled in her career. She takes care of our home and is an amazing cook. She is a great step-mom to our kids and still finds time to make me feel loved. I don’t know how she does it.”
