Mark B. Weinheimer
Mark’s legal practice is focused in order to provide knowledgeable advice and counsel to a wide array of individuals and family-owned businesses, closely-held companies, and their owners and managers, primarily in the business, real estate and estate planning areas. Mark seeks to develop a mutually attentive and respectful relationship with the firm’s clients. Mark brings to his business and individual clients several decades of relevant and valuable experiences, both as a lender and lawyer. His experience allows him to provide sophisticated advice to business owners on a broad range of issues, transactions and industries, and to appropriately counsel and advise companies and individuals on the particular legal issues and associated risks and potential rewards pertaining to the particular situation.
A large part of Mark’s practice is centered on the immediate and longer-term goals for closely-held businesses, including entities owned entirely by members of the same family. He advises clients on issues pertaining to corporate and real estate transactions, and continues to work with clients as they navigate through their own strategic business and family wealth transitions and succession planning.
A sampling of the diverse array of businesses that are included as clients are agricultural enterprises (grain and livestock production, sales and services, marketing and commodities, grain elevators, river terminals, etc.); transportation and logistics; manufacturing, mining and quarrying; commercial and residential construction; real estate (investors, landlords); banks; restaurants and other retail and service businesses. In addition, Mark’s individual client base includes a range of situations, including company executives and managers with employment and compensation matters, stockholder and other co-owner agreements; the grantors, trustees and/or beneficiaries for family trusts established to provide tax-efficient wealth transfers with an overall business or family wealth succession strategy in place.
From formation to exit strategies, Mark handles transactional matters including entity formation; capital and debt raising; due diligence review and related acquisition or sale strategies; drafting and negotiating transactions, closing, and ancillary deal documents; preparing protective agreements for his clients' interests (including buy-sell, employment, non-compete and non-solicit agreements); negotiating and establishing various lease, development, property management, joint venture and other documents for diverse property-focused firms; and completing mergers, acquisitions, divestitures and other strategic business and wealth protection, transition and succession efforts.
Notable Transactions and Results
- Negotiated and documented the sale transaction(s) for a number of limestone quarry business(es), in both Illinois and Missouri, and resultant diversification of proceeds for family members and/or distributions to business owners.

- Represented and advised a sibling throughout a tax-advantaged business separation (corporate split) for a substantial company owned by two brothers in order for the client to be able to more directly seek certainty via control of ownership and management succession, as well as to allow for independent business success based upon the continuing personal efforts of the client and his immediate family members.
