About
MainStreet Advisors, LLC provides portfolio management services to individuals, families, small businesses and non-profit organizations, offering both discretionary and non-discretionary management across exchange-listed stocks, mutual funds, index funds, ETFs and bonds. The firm also provides accounting and tax consulting and its adviser representatives are licensed to sell insurance products, which the brochure identifies as an additional source of compensation.
The firm states it employs both fundamental and technical analysis to construct portfolios and tailors allocations to clients’ financial condition and risk tolerance, monitoring accounts on a daily basis and encouraging at least annual reviews. While MainStreet uses percentage-of-assets fees like many peers, its disclosure notes it also accepts fixed and hourly arrangements and invoices clients, and arranges for fee deductions through custodians when authorized.
Distinctive elements in the brochure include the combination of investment management with insurance brokerage and accounting/tax consulting revenue streams, and a policy to compensate outside financial professionals for client referrals — arrangements the firm acknowledges can create conflicts and requires disclosure. The brochure also clarifies the adviser is newly formed, had not yet commenced operations when the document was prepared, and reports no disciplinary history.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
