Mark J. Seelig

Park Avenue has long been a corridor for corporate counsel and boutique law firms, and Mark J. Seelig fits neatly into that tradition. Business attorneys in this part of Midtown often handle the kind of contracts and disputes that keep New York’s commercial engine humming. The office sits on the 7th floor at 125 Park Ave, New York, NY 10017, just steps from Grand Central, where daily commuters and deal-makers brush shoulders.

From formation agreements to shareholder disputes, the practice covers the essentials most local enterprises encounter. Clients typically need help with regulatory filings, employment policies, or lease negotiations—tasks that can derail a growing company if mishandled. A phone call can clarify which documents are necessary and which pitfalls to sidestep before pen meets paper.
