Griffiths Marshall
Wealth Management
Griffiths Marshall Wealth Management was formed in 2020 when two long‑standing and locally respected firms, Griffiths Marshall Advisory Group and Prosser Knowles, now Perspective (Prosser Knowles), came together to offer clients a fully integrated approach to accounting and financial advice.
Our Story
Griffiths Marshall Advisory Group was founded in 1979 as a Gloucestershire based firm of Chartered Accountants and Business Advisers. From the beginning, the firm has supported a broad mix of clients – from sole traders and growing SMEs to multi million pound organisations. Griffiths Marshall Advisory Group provides a full suite of services, including accounting, audit, tax, business advisory and probate. Their longstanding focus has been helping clients plan with confidence, grow with purpose and enjoy the life they are working hard to build.
Prosser Knowles, established in 1987, became part of Perspective Financial Group Limited in November 2025 and is now known as Perspective (Prosser Knowles), gaining access to wider expertise and resources that enhance the support available to clients. Perspective (Prosser Knowles) financial advisers deliver independent financial advice and wealth management to individuals, companies and trustees, covering areas such as retirement planning, investment strategy and tax efficient saving.
Together, the combined strengths of Griffiths Marshall Advisory Group and Perspective (Prosser Knowles) create a seamless route to trusted, joined up advice across both business and personal finances – helping clients protect, grow and enjoy their wealth with confidence.
