I’m a partner in the BrownWinick law firm and bring 30 years of experience in the business and corporate transactional area.  I represent clients across a wide range of industries providing expertise in the areas of mergers and acquisitions, banking, corporate finance, securities and health law.  I also serve as general counsel to numerous clients.  In representing our clients, I strive to serve as a trusted advisor helping our clients navigate and solve their problems and meet their business objectives.      

My Approach:

My approach starts with listening and understanding your business and the issues and challenges you are facing, along with the opportunities and objectives you desire to achieve.  We will then partner and collaborate to meet your goals, address your issues and maximize your business opportunities.  As your partner, I will strive to provide quick, practical, and cost effective business solutions.  I have also found that anticipating your needs and attending to even the smallest detail is critical.  My ultimate goal is to make sure your problems are efficiently resolved and your goals are achieved. 

More About Me:

 In 1990, I received a J.D., with high distinction, from the University of Iowa and was admitted to the Illinois bar in 1990 and the Iowa bar in 1992.  I graduated in 1984 from the University of Iowa with a Bachelor of Business Administration with a major in Accounting.  I received my Certified Public Accountant Certificate in 1985 from the University of Illinois.

Prior to attending law school, I was an accountant with the public accounting firm KPMG in their Chicago, Illinois office.  This experience provided valuable lessons in understanding client’s financial and tax issues that assist me today in understanding and representing clients.

I have been recognized by Best Lawyers in the areas of Corporate Law and Mergers and Acquisitions, by Super Lawyers in the area of Business/Corporate Law, and by Chambers USA in Corporate/Mergers and Acquisitions.

I am a past member of our Firm’s Management Committee and have served as Chair of the Securities Law Subcommittee and a member of the Business Corporation Law Subcommittee of the Iowa State Bar Association.  As Chair, the Securities Law Subcommittee drafted the new Iowa Uniform Securities Act. During my tenure as a member of the Business Law Corporation Subcommittee, the Subcommittee drafted the new Iowa Business Corporation Act.

I am also involved in a number of civic and industry organizations.  I am currently a member of the Des Moines Partnership Downtown Economic Development Committee and the Des Moines Golf and Country Club Finance Committee.  I have completed two leadership programs – Greater Des Moines Leadership Institute and the Iowa Association of Business and Industry Leadership Iowa.  I am an active member of the Association of Business and Industry, the Greater Des Moines Leadership Institute and the Iowa Renewable Fuels Association.
