About Main Management

An independent, partner-owned investment manager based in San Francisco with a 20+ year track record. Read on to learn more about Main and where it stands today.

Our story

Kim Arthur, James Concidine, and Richard Fredericks founded Main Management in 2002 in San Francisco, CA. Combining their investment insights and belief in maximizing investors' returns, they made a commitment to deliver liquid, transparent, tax-aware, and cost-effective solutions to our clients.

In 2005, Blaine Docker joined Main, playing a key role in the development and expansion of the firm. Today, he leads the Private Clients & Institutional team at Main Management.

The firm celebrated its 20 year anniversary in 2022. Main has grown to ~$4.8 billion in assets under management and advisement, with 25+ employees across its two divisions. Through that growth, Main's ‘client first, exceptional service’ philosophy has remained intact as the core value in each relationship we form.
