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 website (Form ADV) · as of 2026-09-12

Also named here, with no published line of their own (reach them through the firm): Ha Dao (ASSOCIATE), In Memoriam (CO-FOUNDER), John C Backus (Managing Member), Thanasis Delistathis (Managing Member), Jennifer Ann Schretter (Partner), Michael W Zarlenga (General Counsel), John F Burke (Managing Member), Margaret Eileen Varona (Chief Financial Officer).

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
