49ers' Katie Sowers is the first woman and openly gay coach in Super Bowl history

San Francisco 49ers offensive assistant coach Katie Sowers looks on during a warm-up at Levi's Stadium in Santa Clara, California.

(CNN)A source of inspiration came in 2014.

In a historic move at the time, the NBA's San Antonio Spurs hired Becky Hammon as an assistant coach. Katie Sowers took notice, posting on Twitter a picture of herself, saying, "Coming for the NFL."
Now, Sowers is making history herself, becoming the first woman and openly gay person to coach in a Super Bowl. Sowers is in her fourth season in the NFL and is an offensive assistant with the San Francisco 49ers.
"She has done a hell of a job," 49ers head coach Kyle Shanahan said to NBC Sports Bay Area.
    In a prominent Microsoft Surface commercial, Sowers, now in her 30s, shared a letter she wrote to herself as a child.
    "I hope someday I will be on a real football team," she said.
    Later in the commercial, as a 49ers coach, she said, "I'm not just here to be the token female. I'm here to help us win."

    Rejected because of her sexual orientation

    Sowers was born in Hesston, Kansas, a community of roughly 3,800 people north of Wichita. She grew up playing football with her twin sister, Liz. The games were informal, backyard football with the boys.
    "There was no question about playing or not playing," Liz Sowers told NBC Sports Bay Area. "It was just, we played. That's it."
    Sowers attended Hesston College and then Goshen College in Indiana, graduating in 2009. She earned her master's degree in kinesiology from the University of Central Missouri in 2012.
    At Goshen, which is affiliated with the Mennonite Church, Sowers competed in soccer, basketball and track and field. It was then when she came out to family and friends.
    "When it came to me coming out to my parents, it was nothing but love and acceptance," Sowers told NBC Sports Bay Area.
    When her collegiate playing days ended, Sowers asked about taking a position as a volunteer assistant coach on the Goshen women's basketball team. She said was turned down based on her sexual orientation.
    "With coaching being my final destination, in terms of what I wanted to do, I thought it would be natural to ask if I could be a volunteer assistant coach, and my coach called me in and he said they have a lot of parents that have been worried about their daughter being around someone who is gay ... " Sowers said to NBC Sports Bay Area. "So that's not something that they would want around the team. So, he asked that I would not be around the team anymore.
    "I was near tears. He gave me a hug and he said, 'It's nothing personal,' and I remember hugging him but being extremely upset. It was just something that I grieved about for a while, but I decided that I had to move on."
    Goshen College president Rebecca Stoltzfus released a statement Wednesday, saying, "Sadly, in 2009, our policies and the laws of Indiana allowed for hiring decisions to consider sexual orientation. I am glad that Goshen College adopted a new non-discrimination policy in 2015, and I am thankful for the leaders before me who brought this change about, not the least of whom were our students and alumni."
    Sowers looks on before the preseason game against the Minnesota Vikings on August 27 in Minneapolis.

    Second chance

    Sowers said after the rejection from Goshen that she felt lost -- but that it ultimately pushed her to play in the Women's Football Alliance with her twin, Liz.
    "It led me to a second chance at the game that I originally loved the most," Sowers told NBC Sports Bay Area.
    Sowers played eight years in the Women's Football Alliance, first for the West Michigan Mayhem and then for the Kansas City Titans in Missouri. She later became the Titans' general manager.
    Those playing in the Women's Football Alliance are truly in it for the love of the game. They pay to play; there are no salaries. So Sowers, who also was a member of the US Women's National Football Team in 2013, took on a job coaching youth girls basketball in Kansas City.
    One of the girls she coached was the daughter of Scott Pioli, the former general manager of the Kansas City Chiefs. Sowers introduced herself. As the dialogue continued, Pioli, who went on to become the assistant general manager of the Atlanta Falcons, started to look into getting Sowers into the NFL.
    Pioli told NBC Sports Bay Area that it took some time to get the Falcons on board. But in 2016, with Pioli's help, Sowers spent the offseason and training camp with Atlanta through the Bill Walsh Diversity Coaching Fellowship.
    "Finally the year came where they decided that hey, this was a good idea, and then Kyle Shanahan, our offensive coordinator at the time, was 100% on board having her work on the offensive side of the ball," Pioli said.
    After Shanahan left for the 49ers head coaching job in 2017, Sowers, again through the fellowship program, went on to follow him to the Bay Area.
    "I loved having Katie around, loved her the year I had her in Atlanta," Shanahan said to NBC Sports Bay Area. "Some of the coaches came to me at the end of (training camp) and told me how much she's helped and if there was a spot for her to keep her around."
    That fall, Shanahan hired Sowers as a seasonal offensive assistant, making her, according to the NFL, the second woman to ever hold a full-time coaching position league history.
    In a Facebook post, Sowers made a point to thank Pioli publicly.
    "It's important for all to know that dreams are achieved by first finding someone who sees your worth and value, regardless of your gender, and takes the necessary steps to clear a path, even on the path less traveled," Sowers wrote. "Those people are hard to find, but I was blessed to begin my journey in the NFL because of a close friend and mentor in Scott Pioli.
    "Scott's passion for equal opportunity and his belief in a small town girl from Kansas, allowed me the opportunity to follow my passion. Scott continues to do amazing work, opening doors and breaking down walls in the NFL that for years have shut people out. I think we could all learn a little from people like Scott Pioli and find a way to open doors for those behind us."
    Pioli said in a recent tweet that he simply cultivated an unconditional relationship with Sowers.
    "I pr
