About us

Jeisy Castillo
Born in Mexico, raised in Greeley Colorado, I graduated from Greeley Central high school in 2004. After high school, I attended the Institute of Business and Medical Careers where I obtained my Associate Degrees of General Business Administration and General Administration of Legal Office. I attended Aims Community College, Metropolitan State College of Denver and Florida International University, all while working full time for various industries.
My experience started with managing a rental car office in Greeley, to being a manager and bookkeeper of four construction companies in Windsor in 2009. Here I learned the majority of the skills I use today: customer service, bookkeeping, managing a business, bank reconciliations and working with subcontractors. I also experienced, first hand, the importance of small businesses and their impact on the community. After moving to Denver in 2010 and while attending Metropolitan State College of Denver, I became the Treasury Accounting Coordinator for American Blue Ribbon Holdings, also known as, the corporate office for the Village Inn restaurants. Here, I managed and made sure monies from all the Village Inn and sister companies around the United States made it to the corporate bank.
After getting married in 2011, my husband and I moved to Miami Florida. I attended Florida International University and worked for Chetu Inc., a software building company. Later in 2013, I worked as a Staff Accountant for a retirement village that consisted of independent living, assisted living and Health Services. Recently, I started a family and I am a proud mom of a two girls and one boy. For the last 4 years I have been the bilingual business consultant for the Small Business Development Center here is Greeley, while also running my ProBook Consulting, LLC business and this community based business we call Colorado Community Tax Services.

Born in Mexico, raised in Greeley Colorado, I graduated in 1999 from high school and in 2005 from the Institute of Business & Medical Careers with an Associates in Business Technology - Medical Emphasis. Over the following years, up to 2008, I worked mainly in administrative customer services, medical billing, processing insurance claims and also became the commercial accounts manager at Quick Care, here in Greeley Colorado. For seven years after, I was a loan processor for VanDyke Mortgage Corporation where I not only processed loans, and helped the community purchase their dream homes, but also assisted in marketing, helped build client relations and managed the lending office. Since 2017, I became a licensed sales producer for Allstate where I assist customers with their property, life & auto insurance needs. Currently, I am one of the owners for Colorado Community Tax Services, where I will enjoy helping my community with their various needs. I am also sitting on the CEOS board as the Treasurer & my current hobbies include traveling, being with my husband, my two grown boys and my baby girl that is about to make me a grandma.
