Colorado’s #1 Basketball Pro-Am
Achieve More Through Community
The 303 League is Denver’s hottest Pro-am and has become the heart and soul of Summer Basketball. The league started its first successful run in June of 2022, which brought out NBA players, neighborhood legends, and overseas stars.

The 303League was founded by Shae Kelley, a WNBA champion and overseas professional basketball player. Born and raised in Park Hill, Denver, Kelley’s inspiration derived from
attending the old Joint Effort Pro-am where her love of the game grew immensely.
Having this opportunity in her formative years pushed her to become one of the most dominant women’s basketball players in the game today. Being able to provide the community and youth with the same experiences and opportunities she had is where her passion for the Pro-am came about.
