Clive Grimbleby, CPA, is a visionary leader and one of the founders of Grimbleby Coleman Advisors & Accountants. After starting his career and honing his accounting skills at a large international firm in Sacramento, Clive took over his father Roy Grimbleby’s practice in 1981. Over the years, Clive and his partners transformed Grimbleby Coleman into one of the largest and most respected accounting and advisory firms in Stanislaus County. The firm’s tagline, “It’s the people behind the numbers,” reflects the core of this transformation. In 2021, he completed a successful business succession by transitioning leadership to his son, Ian Grimbleby, CPA.

Respected for his calm, forward-thinking leadership, Clive has become known for simplifying complex business challenges. He specializes in structuring family-owned enterprises and has helped countless small and large companies navigate their operational challenges and identify and capitalize on economic opportunities.
