Who to call

the organisation, the role and the published line, with the filing or website that published it; revealed to signed-in accounts

The firm's published line

Revealable: 1 business phone (Form ADV), 1 office address (Form ADV), 1 website (Form ADV) · as of 2026-09-13

Also named here, with no published line of their own (reach them through the firm): Kyle Gionis (Chief Accounting Officer), James Kaon Lam (Managing Director), J. Chris Jones (Founding Partner / Advisor), Samuel Howland Pyne (Managing Director), Steven Charles Ludwig (Chief Compliance Officer), Michael Scott Jones (Managing Director And Managing Member), John a Strom (Managing Director And Managing Member), James Christopher Jones (Trustee).

Who to call is the organisation, the person's role and the line they published themselves: a business phone, office address, website or profile link from Form ADV, Form 13F or their own website, with that source named on every value. The counts above are what a reveal returns; a personal email is rarely published, so most reveals are the firm's line. Never data bought from a provider, never anything personal. Reveals by plan
