Castle Rock Bank joins the Guaranty Bank Family.


We are pleased to announce that on October 27, 2017 the Guaranty Bancorp and Castle Rock Bank Holding Company merger was completed.

On December 4, 2017, we will take the final step to integrate our systems and change the name on the buildings to Guaranty Bank. While the name will change, the local decision making, personalized solutions and exceptional service you have come to expect will remain the same.

All branches will be CLOSED on Saturday, December 2, 2017 as we complete our system conversion.
