The short version

MARK B. TRESNOWSKI is listed as an executive officer, director, and promoter on 28 SEC Form D filings by 21 issuers between Feb 2010 and Dec 2025. Largest by amount reported sold: Madison Dearborn Capital Partners VI-B, L.P. (Chicago, IL — pooled investment fund — 2010; $3.08B reported sold to 166 investors), Madison Dearborn Capital Partners VI-A, L.P. (Chicago, IL — pooled investment fund — 2010; $3.08B reported sold to 166 investors), MADISON DEARBORN CAPITAL PARTNERS VII-A, L.P. (Chicago, IL — pooled investment fund — 2015; $1.85B reported sold to 162 investors), MADISON DEARBORN CAPITAL PARTNERS VII-B, L.P.

(Chicago, IL — pooled investment fund — 2015; $828.1M reported sold to 33 investors) and 16 more (all listed below).

What this means That is a lot of deals — 21 separate companies raised money with this person listed as executive officer, director, and promoter, over about 15 years. Across those companies the filings report $13.38B sold in total.

Listed alongside PAUL J. FINNEGAN (24 shared filings), SAMUEL M. MENCOFF (24 shared filings), TIMOTHY P. SULLIVAN (22 shared filings), VAHE A. DOMBALAGIAN (22 shared filings), NICHOLAS W. ALEXOS (20 shared filings) and 53 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around MARK. Each name links to their own page.

All 21 issuers belong to the sponsor group Madison Dearborn (97 issuers, $43.66B reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Madison Dearborn has 97 companies on file and $43.66B reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 28 public filings for MARK B. TRESNOWSKI and found 6 differences, 1 worth asking the sponsor about: 6 paid sellers are listed without a CRD number; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.

How this is counted

Counts come from Form D Items 12–15 on the filings in our index (latest filing per offering; one offering = one SEC file number; an amendment updates its offering rather than adding one). "To insiders" = gross proceeds used for payments to executive officers, directors or promoters. "—" = not reported on that filing. Amounts marked (est.) were reported as estimates. "Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.

Counted across every filing this person is listed on (latest filing per offering, per issuer).

Deals 21

Every issuer that named Mark B. Tresnowski on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.

One team, 97 deal companies. Mark B. Tresnowski is listed on 21 of them.

Sources

Issuers are grouped when their Form D filings share related persons, a management entity or a business address (automatic match from the filings). "Listed" marks the issuers that name MARK B. TRESNOWSKI.

Same business address

51 other issuers file from the same address (first 50 shown)

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

Registrations and other filings

Adviser registration (Form ADV)

A person is never an adviser firm. 8 of the 21 issuers this person is listed on match a Form ADV adviser (searched 24,962 advisers as of Oct 2, 2026): MDCP Co-Investors (Patriot II), L.P., MDCP Co-Investors (Patriot), L.P., MDCP CO-INVESTORS (SP), L.P., MADISON DEARBORN CAPITAL PARTNERS VI EXECUTIVE-B, L.P., MADISON DEARBORN CAPITAL PARTNERS VI EXECUTIVE-A, L.P., Madison Dearborn Capital Partners VI-C, L.P., Madison Dearborn Capital Partners VI-B, L.P., Madison Dearborn Capital Partners VI-A, L.P..

Other offering types (Regulation A and Regulation Crowdfunding)

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to MARK B. TRESNOWSKI by design.
