Advisor profile scores displayed on this site are derived using the following criteria. Step 1: An advisor profile rating starts with a baseline score of 90 points. Step 2: The advisor score is increased from the baseline after screening for 3 criteria: years of experience, industry credentials and completeness of profile. Step 3: The advisor score is decreased after screening for publicly available disclosure events such as litigation or regulatory matters. Such decreases relate to the existence of a disclosure and, in most cases, do not account for timing, magnitude or severity of such disclosure. Many other factors are not considered in the scoring such as financial stability, fees, affiliations and educational background, and you should carefully consider these factors. The criteria are based on information Wealthminder deems helpful and available at the time of the scoring. Scores do not vary based on qualitative feedback from users. Advisor presentation and visibility and allocation of proposals will vary for advisors who pay a marketing plan program fee. Wealthminder does not recommend or provide any warranty or guarantee of the quality or suitability of any specific advisor or products or services offered by such advisor. Please consult regulatory sites for additional information about advisors’ background.
