SEIA serves individuals, high-net-worth clients, trusts, retirement plans, and other institutional and charitable clients through a multi-team advisory platform of roughly 140 advisors and multiple advisory programs. Its service mix includes investment management across several models (non-discretionary and discretionary), modular and comprehensive financial planning, retirement plan consulting, and investment consulting.

The firm’s investment process is driven by an in-house Investment Solutions Group and an Investment Committee that combine strategic macro asset-allocation with tactical adjustments, using quantitative screens and qualitative research consistent with modern portfolio theory. While SEIA operates discretionary platforms, a large majority of its assets are managed on a non-discretionary basis—advisors commonly recommend trades for client approval rather than acting solely on discretionary authority—which is atypical for firms of this size.

SEIA’s brochure discloses several operational features that distinguish it from many peers, including formalized policies for use of artificial intelligence with human review, a cash management relationship it makes available through a third‑party provider (with related compensation disclosures), and an affiliated tax-preparation entity that can be offered with fee-credit arrangements. The firm also offers targeted strategies that may employ options and structured-note SMAs, participates in third‑party platform relationships (including AssetMark and promoter/referral arrangements with large custodians), and maintains affiliated broker-dealer and insurance entities—arrangements that the firm discloses as potential sources of conflicts of interest.
