Third-party rankings and recognition from ratings services, or publications, are no guarantee of future investment success. Working with a highly-rated adviser does not ensure that a client or prospective client will experience a higher level of performance or results. These ratings should not be construed as an endorsement of the adviser by any client and they are not representative of any one client’s evaluation. Generally, ratings, rankings, and recognition are based on information prepared and submitted by the adviser. Each reprint or e-print has its own unique disclosures related to the criteria and requirements for receiving such award and it is important for clients to understand this when evaluating Boston Private Wealth LLC (BPW) and its associated persons. Read more about award descriptions and criteria.

Although BPW and its advisors do not pay fees for awards or ranking, there are instances where BPW will pay for reprints or advertising after receiving recognition. This represents a conflict of interest for the firm issuing the award or ranking, however, BPW believes the awards and rankings advertised are bona fide.
