Also named here, with no published line of their own (reach them through the firm): Jonathan Sutton Day (Shareholder and control person), Dorothy Willametta Day (Shareholder and control person; Trustee, Dorothy Day Trust dated 2/13/2008), Thomas Joseph Deegan-Day (Shareholder and control person; Trustee, Joseph Deegan Day Trust dated 4/13/2004), David Reid Covin (Chief Financial Officer), Sumo Gupta (Portfolio Manager), Robert Marvin Miller (President, Secretary and Chief Compliance Officer), Peter Weldon Carlton (Chief Executive Officer and Chief Investment 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
