"With Great Power Comes Great Responsibility"

As San Diego continues to grow, there is an increased awareness of our community’s critical needs. Recurring themes that plague large cities across the nation continue to emerge—homelessness, environmental preservation, struggling schools, failing infrastructure, underserved communities, and support services for the growing active duty military as well as the veteran population .

All of these are a part of San Diego’s growing challenges. With that in mind, we all have a responsibility to give something back. At 365 Events San Diego, we are committed to creating a culture of  community support to meet these challenges head on and make San Diego an even better place to live for all!

Carlen Haag

Carlen Haag is a true San Diego native. Her love for San Diego and the community in which she lives, has led her to a life dedicated to making every day a little better than before. Growing up, Carlen regularly volunteered with local philanthropic organizations, and enjoyed spending her time helping others. She has finally decided to combine her passion and her skills to do something that really will make a difference.

For the past decade, Carlen has worked with local nonprofits sharing her expertise in leadership and program development, grant writing, and fundraising. It was here, Carlen realized how a positive influence and a dream can push a person to accomplish things they never thought possible. She has witnessed firsthand how volunteering can change a person’s outlook on life. It is her goal to be able to provide that opportunity for all of San Diego community. 

In her spare time, Carlen is off to the races, literally with cars and horses. She can be found cheering on her favorite driver and rider, her children. Her son, Shane is proud to be a part of the Southwest Lightning Sprint inaugural season, while her daughter, Grace can be found riding horses on Fiesta Island or competing in shows in Valley Center, CA. Outside of racing season, you will most likely find Carlen and her daughter Sydney strolling down Main Street USA, Disneyland.
