Leadership Honors

Congratulations to our colleague and partner Edward Sluys for having been named one of the best young leaders in the St. Louis business community by the St. Louis Business Journal, who included Ed in their 2014 ‘30 Under 30’ list. 


Congratulations to our colleagues, partners and CHGO attorneys Leland Curtis, Kevin O’Keefe and Carl Lumley on their inclusion in the 21st Edition of The Best Lawyers in America, with additional kudos to Kevin for being named the Best Lawyers’ 2015 St. Louis Municipal Law “Lawyer of the Year.”

Chosen by their peers, inclusion in Best Lawyers – the oldest and most respected peer-review publication in the legal profession – is widely regarded by both clients and legal professionals as a significant honor. For more than three decades, Best Lawyers lists have earned the respect of the profession, the media, and the public, as the most reliable, unbiased source of legal referrals anywhere.

The lists of outstanding attorneys are compiled by exhaustive peer-review surveys in which tens of thousands of leading lawyers confidentially evaluate their professional peers. Lawyers are not permitted to pay any fee to participate in or be included on our lists.

The 21st Edition of The Best Lawyers in America (2015) includes 52,488 attorneys in 137 practice areas, covering all 50 states and the District of Columbia, and inclusion in this year’s publication is based on more than 5.5 million detailed evaluations of lawyers by other lawyers.


Congratulations to our colleague and partner Patricia K. Susi, who recently was recognized for her outstanding achievement and designated Distinguished Alumnus by the Political Science Chapter of the University of Missouri – St. Louis Alumni Association.
