We are Mitchell & Mitchell.

At Mitchell & Mitchell Asset Management, we manage money with purpose, process, and partnership. We build model portfolios designed to deliver consistent, risk-adjusted outcomes across all market environments — and we do it with a structure built for advisers and clients, not spreadsheets and benchmarks.

We’re a discretionary fund manager with a clear mission: to help professional advisers deliver better outcomes, with less operational burden and more investment confidence. Our portfolios are evidence-driven, risk-aware, and grounded in disciplined execution.

OUR STORY

Mitchell & Mitchell was born out of experience — over a decade of hands-on portfolio design, adviser feedback, and real-world client outcomes.

Before launching as a discretionary manager, we spent many years operating advisory model portfolios within the GSI group. That time taught us a lot: how to build risk-based strategies that clients could understand, how to support advisers with investment insight, and how to evolve portfolios through shifting markets.

But as the regulatory landscape changed and expectations around governance grew, the cost — in time, oversight, and compliance risk — increased significantly. What once felt nimble began to feel strained.

Rather than compromise on quality or process, we chose to formalise what we already did best — and Mitchell & Mitchell Asset Management was the natural next step.

We took everything we had built informally — the investment insight, the adviser trust, the outcomes-first philosophy — and wrapped it in a professional discretionary structure. One that improves efficiency, strengthens oversight, and makes life easier for everyone involved: advisers, clients, platforms, and investment partners.

Today, we offer Model Portfolio Solutions (MPS) rooted in real experience and shaped by a decade of practical application — not product development theory.

OUR TEAM

We are a team of investment and financial services professionals with deep experience across financial planning, asset management, operations, and regulatory oversight.

While we retain full discretion over our portfolio decisions, we operate with a culture of accountability, rigour, and humility. We are here to be your investment partner — not just your provider.

At the core of our approach is a team of specialists with a shared focus: delivering investment strategies that balance performance, governance, and practical application. Together, we blend investment insight with operational rigour.

Our backgrounds range from adviser practice to institutional investment governance, giving us a uniquely well-rounded view of what it means to manage money responsibly.

As a boutique investment manager, we take pride in being highly accessible, responsive, and aligned with our advisers. We believe that success lies not just in performance, but in clear communication, strong process, and trusted relationships.
