About Us

About Call24 Communications, Inc.

Family owned and operated for over 40 years.  Many times the choice of a call center is a quick one. It is often driven by cost. In reality this will be the company that answers your phone, representing you and your company.  What separates the quality of call answering services?  There are many different aspects that need to be looked at. The first is- who are the owners? Wendie Zimmerman started Call24 in 1977. She brought her son Scott Zimmerman into the business in 1994.  Both owners have an active part in the day to day running of the business.

In addition to their role as owners of Call24, Wendie and Scott are also actively involved in the community. Scott is a Little League Coach at Alhambra High School, showcasing their commitment to making a positive impact both in and outside of their business.


Experience is one of the most valuable assets a call center can offer.

An experienced staff is an asset.  These are ultimately the people who will be answering your phone.  A well seasoned and experienced staff can make all the difference in the world.  Our staff is our family and your callers will know this with every call.
