Christina Diehl, Coldwell Banker

A passionate and experienced Realtor® with over 15 years of experience, Christina always held an interest in the real estate industry. Raised in Lititz, PA, she developed an early interest in real estate investments, which ultimately led her to pursue a career in real estate full-time. Her pursuits motivated her to educate young women on financial literacy, resulting in Christina publishing her first book, MoneyGirl in 2020.

Christina’s commitment to the industry has made her an active member of the Lancaster County Association of Realtors®. She has served on LCAR’s Government Affairs Committee for ten years along with serving on LCAR’s Board of Directors for six years. This has led her to serve as LCAR’s 2024 Secretary before she moves to the role of LCAR’s President-Elect in 2025.

In addition to the association, Christina also acts as the Chair of Lancaster’s CRIZ Authority after serving on their board for six years.
