Entering Thunderbirds Territory

Tbirds Fall Season Party 11/5, 12pm!

We'll have our end of the fall season party next Sunday, November 5, from 12 to around 3 at Martin Park. It looks like it will warm up again by then; remember to set your clocks back the night before! Please feel free to join us even if your player didn't play this fall; especially for new players, this is a great time to meet teammates and other families. We'll have some softball going on the field and will have burgers, veggie burgers, and hot dogs on the grill. Please bring a drink, side dish, or dessert.

About Boulder Thunderbirds

“Baseball is ninety percent mental and the other half is physical.” – Yogi Berra


Boulder Thunderbirds Baseball is a competitive 9U-14U youth baseball tournament club based in Boulder, Colorado. The Thunderbirds were founded in 2016 and are a 501(c)(3) non-profit, independent sister organization to South Boulder Little League. Our goal as an organization is to allow our players to grow their skills and love of the game so they will be able to play as long as their ability will take them. Our coaches do this by fostering a fun, low-stress environment focused on team building on and off the field, encouraging sportsmanship, confidence, and character building.


Thunderbird baseball is designed to be a complement to the Little League experience and the 9U-12U levels, to get our players experience playing with great teammates against great competition so that they will be prepared to make and succeed on their Little League All-Star teams. The great majority of our players are able to achieve this goal. At the 13U-14U levels, our goal is to help our players successfully navigate the transition from Little League to high school baseball.

Our coaching philosophy is a whole child approach. We want athletes who enjoy playing multiple sports, engage in other non-sport activities, and have a passion for baseball. All of our players train and experience gameplay at multiple positions through our developmental approach. Everyone plays and contributes, because nobody gets better on the bench.

The Thunderbird is a symbol of strength, protection, and caring. That coincides well with our main team goals. We strive to build teams that love spending time together on and off the field, made up of players who show great sportsmanship and support for their teammates. As coaches, we support players in their athletic goals, while also providing a safe place for them to build character and self-esteem. We strive to be effective at supporting families in the many challenges young people are dealing with every day.

By meeting these goals, we build winning teams of players who are able to build their skills and self-confidence as players in a supportive environment. We avoid burnout and create players who will love playing baseball as long as their ability will carry them.
