Martinez was 67 years old. He touched so many young lives through sports spending 32 years coaching at College of San Mateo.
"Tom's legacy is hundreds and thousands of young people that he cared for, mentored, disciplined," Pastor Frank VanderZwan said.
Outside the college he was known as the man who groomed star quarterback Tom Brady from the age of 12. That also happens to be Brady's number with the Patriots.
On his Facebook page, Brady posted a statement and a picture of Martinez.
While Brady attended Friday's services, it was his father who spoke on his behalf.
"Tom was one of those people who come along once in a lifetime and if you have it happened once in your life you are very fortunate," Tom Brady Sr. said.
In a recent interview with ABC7, Martinez spoke of their relationship.
"You have a pretty good coach, that coach is going to be someone you look up to, and they don't do any wrong, I mean they're your man and so we started out with that relationship," Martinez said.
Martinez died of a heart attack during his dialysis treatment. He had been on the waiting list for a kidney transplant for two years.
Friday, his son remembered how his father valued work.
"Find something you love, just don't do it, do it well, do it with passion and commitment," Tom Martinez Jr. said.
The family wishes any donations be made to the Tom Martinez Scholarship Fund or to www.matchingdonors.com, an organization helping patients who need an organ transplant.
