About
Siharum Advisors, LLC provides discretionary investment management and investment consulting to individuals, high‑net‑worth clients, pension and profit‑sharing plans, trusts, estates and charitable organizations. Client relationships are typically tailored by portfolio size — consulting engagements are generally for portfolios above $20 million and discretionary management for portfolios generally above $2.5 million — and the firm reported $687,464,747 in assets under advisement as of December 31, 2025.
The firm operates an open‑architecture, manager‑of‑managers framework that identifies third‑party investment managers and combines actively managed and index‑based products to construct diversified, customized portfolios. Siharum’s process relies on quantitative screening and qualitative due diligence (including on‑site visits) and the firm generally avoids recommending direct purchases of individual securities, redeploying legacy positions into its selected manager products.
Siharum highlights and distributes investment performance in its client reporting and firm materials — a practice the brochure describes and that is less common among similar team firms. The brochure also emphasizes a concierge client service model with customized quarterly performance reports and annual reviews, detailed third‑party manager due diligence, and the occasional provision of trustee services for client‑affiliated trusts.

We'll help you think it through – whether you ultimately need an advisor or not.
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.
By using our service, you agree to Warmer's Terms of Service and Advisory Agreement and Privacy Policy. Logos provided by Logo.dev
