Despite an impressive 51 years in the sports industry representing Crème de la Crème of athletes, Leigh Steinberg’s career as an agent and philanthropist is far from over.
Steinberg’s approach to athlete management, which includes negotiations on top-tier athletes as 64 first round of NFL drafts for just the first eight years of his career, Elite MLB players and Olympic athletes, have been strategic in both Hustle and Heart for decades.
The inspiration for “Jerry Maguire” signs athletes who dream of both reaching the Hall of Fame status and embedding philanthropy of the mind in their loyal fanbase.

“Whether it’s creating a charity at their high school, a similar thing on their colleges, charity funds at the professional level, where they take some problems they would like to tackle and create a foundation,” Steinberg told Pakinomist Digital, “all with the concept of athlete as a role model.”
Steinberg highlighted the NFL Superstar and Client Patrick Mahomes’ initiative, 15 and the Mahomies Foundation, as an example of what is possible when elite athletes use their names to raise awareness and funds for a case.
Mahomes’ foundation created in 2019 is dedicated to improving the lives of exposed and underrated young people. Most recently, the Fund revealed the expansion of scholarships in childhood education and reported by 2024 that youth volunteers contributed $ 2.6 million in service time through the organization.

“I’ve been very involved in restoring what an agent’s responsibility is,” Steinberg said. “I think part of it is to look after a player’s health.”
In addition to working with athletes to choose a basic focus, Steinberg bells daily as chairman of the Leigh Steinberg Foundation, aiming to educate and raise information about the risk of athletic concussions and fund prophylactic treatment of concussions and heal the concussion.
“In a sport like football, which is a traffic accident in every play and concussion is an ugly ghost, I have tried to be proactive over the years,” Steinberg told Pakinomist Digital. “I had a crisis of conscience back in the 1980s because I represented half of the starting quarterbacks in the NFL. They kept hit in the head and we would go to doctors and ask how many there are too many? When should they consider retirement? And they had no answers and then I started holding concussion conferences back in 1994.”
Since its inception, Steinberg said the foundation has worked with treatment clinics Iqmind and Nestre to identify two new breakthrough technologies, transcranial magnetic stimulation and neurofeedback that heals a concussion brain through the theory of neuroplasticity.

“We are also trying to provide treatment of underrated societies that do not necessarily have a way of dealing with brain health,” Steinberg said. “So we look to bring treatment to a number of people who would otherwise not have it.”
In just a week, Steinberg says the foundation raised $ 500,000, which will partly be assigned to host seminars and spread attention to parents with children in athletics.
Among the votes behind the fund’s public service announcement and education campaigns are former NFL quarterback Warren Moon, the former defensive end Bruce Smith and former linebacker Ray Lewis. Steinberg hopes to welcome female footballers to the team of messengers in the future.
“There’s hope out there and people have to know they can get treatment,” Steinberg said.
