About
Clark Lewis provides ongoing fiduciary financial planning and investment management to individuals, high‑net‑worth clients, charitable organizations and businesses, and also offers professional consulting to business clients on topics such as strategic planning, operations, supply chain, lean management, marketing and project management. The firm delivers customized financial plans and portfolio supervision on a discretionary or non‑discretionary basis and states it does not impose a minimum account size.
The firm’s investment process is grounded in Modern Portfolio Theory and primarily uses passive vehicles such as index mutual funds and ETFs, while incorporating fundamental, technical, cyclical and charting analysis when constructing investment policy and making allocation decisions. Clark Lewis may implement portfolios using third‑party managers and TAMP platforms—naming Adhesion Wealth, Envestnet UMAX and TD Ameritrade’s SMA marketplace in its brochure—and provides ongoing monitoring and quarterly reporting to clients.
Noteworthy features compared with peers include a fee approach that caps advisory charges and adjusts that cap annually for inflation rather than relying solely on a scalable percentage of total assets, and the firm’s provision of separate professional consulting services outside the RIA practice. For a small, solo‑run adviser managing roughly $1.3 million for a small client base, the combination of a capped fee philosophy, access to multiple institutional sub‑advisors, and business consulting capabilities is an uncommon mix among independent advisers.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
