Best-In-State Wealth Advisors are selected for the Forbes rankings by SHOOK Research. Rankings for 2024 were published in April 2024 based on data from 6/22 to 6/23. The ranking for 2025 were published in April of 2025 and were based on data from 6/23 to 6/24. No fee was paid for participation in the rankings. The rankings are based on an algorithm of qualitative and quantitative data, rating wealth advisors with a minimum of seven years of experience and weighing factors like revenue trends, assets under management, compliance records, industry experience, and best practices learned through telephone and in-person interviews. 

Portfolio performance is not a criterion due to varying client objectives and a lack of audited data. The rankings are not indicative of future performance, and there is no guarantee of future success. For additional information, visit www.forbes.com
