Linda May, Accountant
Linda grew up in Santa Barbara with aspirations of a career in computers. Circumstances were such that college was not an option. In 1970 Linda met and married her soul mate and they had two children. In 1977 they moved to Santa Maria and later to Nipomo. In the late 1970’s Linda went back to school to pursue a career in computers. During that time while working as a computer operator, she was presented with the opportunity to work in the accounting department and decided she preferred accounting to computers. In the mid 1980’s Linda and her husband purchased a retail store and began a 25 year adventure as business owners where Linda handled all things IT as well as the accounting for the business. The recession of the last decade led to the closure of the store and another career change. Since that time Linda spent a few years working for a non-profit in the accounting department, then for Eggen & Associates where she became a staff accountant. Linda has over 40 years of experience in all things accounting and is a Quickbooks Proadvisor. Linda began working at Clark & Cassidy, Inc in 2018.
