    About Mountainside JBO

    Mountainside Junior Baseball Organization (JBO) is a 501(c)(3) non-profit organization that was established in 2017 to compete as an affiliate in Oregon's Westside JBO district, while offering a youth baseball playing alternative in the Mountainside High School district.

    The Mountainside JBO program is directly aligned with Mountainside High School and works closely with Ryan Fobert, the Mountainside High School Head Varsity baseball coach, and his coaching staff.   This strategic alignment aims in helping to provide the area's youth with the development, skills and competition needed to not only flourish as youth players, but also provide a segue to high school baseball.  

    The goal of Mountainside JBO is to build a league of players who reside in the Mountainside High School boundaries and allow them to compete against other players of equal age and skill, while ultimately achieving their full baseball potential. And because of its connection to the the high school program, Mountainside JBO is in a unique position to prepare your child to play High School Baseball at Mountainside.
