* The Forbes Best-in-State wealth advisor ranking, developed by SHOOK Research, is based on in-person telephone due diligence meetings, and a ranking algorithm that includes: Client retention, industry experience, review of compliance records, firm nominations; and quantitative criteria, including: assets under management and revenue generated for their firms. Portfolio performance is not a criterion due to varying client objections and lack of audited data. Neither Forbes nor SHOOK Research receives a fee in exchange for rankings.
