The Partnership

The partnership behind the firm.

Hart David Carson LLP is 63 attorneys practicing under one name, from offices in Chicago and Oakbrook Terrace and the cities where our clients are. It is led by two partners, Joel J.H. Funk and Jonathan D. Herpy, Sr., who have grown the firm from a single Downers Grove office into a corporate and private-capital boutique with offices in London and Dubai. This is the firm they made, and the bench they built around it.

Downers Grove, Illinois

It started in a strip mall.

Hart David Carson's first office was a suite in a strip mall in Downers Grove, Illinois. The partnership was small, the instincts were complementary, and the conviction was that sophisticated counsel did not have to come wrapped in the overhead of a national firm. Joel J.H. Funk built the corporate side: mergers and acquisitions, corporate governance, and the structures that hold a company together. Jonathan D. Herpy, Sr. built the capital side: middle-market and pre-IPO M&A, private equity, capital markets, and private capital, and from 2014 the frontier of digital assets, before most of the profession had a word for it.

What they were building was a way of practicing, with senior judgment on call and scaled to the moment. They went early into industries whose rules were still being written, stayed as those markets matured, and let a dated record do the work adjectives can't. Brandon Carson Hall joined in January 2015, and the firm added his name in 2017. From that suite the firm grew into Chicago, then Elmhurst and Oakbrook Terrace, then London and Dubai, then a partner network reaching across five continents.

The strip mall is the point. This is a partnership that earned its altitude and still answers the phone.

The Partners

Two partners with complementary practices. However large the team a matter requires, one of them answers for the whole of it, and you have that partner's direct line.

The Model

A partner network of independent firms, assembled per matter.

We do not hand you an org chart and ask you to find your own way through it.

Behind the partners sits a bench of focused counsel and partner-network firms, named to your matter at engagement. It covers the corporate, tax and regulatory ground a deal crosses, the disputes that follow it, and the frontier practices the firm has held since before they had rules. The bench is a pool rather than a fixed roster you are assigned to. We draw from it the seniority and discipline the matter in front of you needs, then stand the team back down when the work is done.

Most of our attorneys serve the firm as counsel: they practice exclusively with Hart David Carson, under its name and its professional standards, and are engaged by the firm rather than employed by it.

That gives you a deep bench across corporate, capital markets, and private wealth with the accountability of a boutique. When a deal demands cross-border structuring, a regulatory answer, or a dispute that has to be contained, the coverage is there, and between matters you are not paying for a department you don't need. The partner stays the same from the first call to the last, and the team around them changes with the work.

The model exists for the inflection point. It puts senior judgment on the decision that cannot be made twice, in the amount the moment requires.
