There is no excuse for leaving a client hanging.” This approach to his work fosters a strong sense of loyalty among his clients. As a result, client turnover in the firm is among the lowest in the industry.

Contact Elizabeth Nigro

Elizabeth Nigro, CPA


Elizabeth Nigro began her public accounting career in 1996, immediately after graduating from California State University, San Bernardino. But her passion for helping clients with the complex area of tax began ten years earlier, working as a local tax practitioner. She honed her tax skills for ten years before completing her accounting degree. After graduating, she went to work at a public accounting firm to gain valuable accounting experience, and then at a large school district. Elizabeth and her husband Jeff started the CPA firm of Nigro & Nigro in 1999.

Elizabeth has a very loyal client base, and it is a direct result of her personal involvement with each and every one of her clients. “It is critical to take the time to understand every client’s unique situation and their concerns before I work on a solution for them.” Elizabeth also spends a significant amount of her time on professional development and research, so that she can always stay “up-to-the-minute” on the latest laws and regulations that affect her clients.

She currently provides accounting, tax, and consulting services to her clients, which include individuals, partnerships, corporations, privately-owned businesses, and nonprofit organizations. In addition, Elizabeth oversees the firm’s Business Consulting Group, which affords her the opportunity to do professional consulting work for non-profit organizations.

Elizabeth has lived in the Temecula Valley since 1983, and is married with five children and four grandchildren. Outside of work, she enjoys travel, particularly to Kauai, hiking, gardening and reading. Her favorite hobby of the last few years, however, is being a grandmother. She enjoys spoiling her grandchildren at every opportunity.
