William Sinclair Weiss - Certified Public Accountant

bill@wsweisscpa.com

William Weiss, best known as Bill, was born in Pasadena, California. He grew up in Pomona with his parents and 2 younger brothers. He graduated from high school at the age of 16 then attended Mt. San Antonio College, where he completed his Associate in Arts degree. After community college he went to the Cal Poly Pomona where he completed his bachelor’s degree of Science in Business Administration with a major in Accounting. After college he worked ten years in public accounting at a local Firm and became a CPA in California in January, 1984. Eventually he moved to Williams AZ and worked for the Grand Canyon Railway, as well as running his own tax practice on the side. As he was working for the railway he moved to Flagstaff and ended up meeting his future wife in a church singles' group. Once married he unofficially adopted Sophia’s two daughters as his own, as they weren’t planning to have any more kids. To their surprise three years later, Savanna came along. After 14 years as Controller for Grand Canyon Railway, he made a job transition to being the Controller for a local mining/cinder business, Flagstaff Landscape Products, while continuing his tax practice on the side. After ten-year as Controller he was approached about buying the CPA practice of Mary Jo Heher in Flagstaff. Wanting to keep his family in the town they know and love, he decided to make the move to a full-time business owner. With a miracle he was able to buy the practice and merge it with his existing business. Now he runs his tax practice, WS Weiss CPA PC, full-time. He really enjoys making it a family business and loves having his youngest daughter and grandson working for him. He hopes to one day pass his business and knowledge to his daughter Savanna. When he’s not working, he loves to build his family tree on ancestry.com, playing strategy games, attending church and watching his daughter play/coach softball.

She is a very fast learner and has many dreams of going to school in the future to earn her degree and become a CPA. She is hoping to continue her tax education, hopefully to the point that she could take over and run WS Weiss CPA PC. At her current position, she is working hard on learning everything she can and giving the best customer service possible. She hopes one day to run the business as well as her father does. When she’s not working she likes to spend her free time making homemade candy, crocheting blankets, and playing video games. She also really loves kids and leads the Nursery ministry at the church.
