J. Timothy Cerney | Mary Jo O'Donnell, Associate | Julie D. Stahl, Associate

Excellent Insurance Defense Attorney

I am the National Claims Director for a mid-size TPA and I have worked with Mr. Cerney for approximately 18 years on litigated insurance defense matters. The results on all cases have been so successful and his legal knowledge and acumen are so advanced, that I use Mr. Cerney exclusively on litigated cases throughout Illinois and can state for the record, he has never lost a case or obtained a bad result for any of my clients.

Mr. Cerney is attentive, knowledgeable and responsive. His firm is not large, but they have been able to successfully defend cases with substantially large exposures to very small matters without any inefficiency.

I very highly recommend Mr. Cerney and his firm fully for any insurance defense work or other litigation matters. His dependability and skill are as good as any attorney with whom I have ever worked.

Outstanding Attorney/ Law Firm

Mr. Cerney and his law firm have represented my two companies, along with me and my family, for almost 30 years in various litigation matters, business transactions and personal matters, including defending bodily injury lawsuits, handling business and commercial lawsuits, general corporate matters and transactions, such as a recent complicated real estate transaction he favorably negotiated and structured. We have always received very successful results.

Mr. Cerney and the other attorneys in the firm are outstanding, experienced attorneys, and are very responsive and easy to work with. I strongly recommend them.

Great Attorney

Tim Cerney has been the attorney for my insurance business, and me personally, for over 30 years. In that time he has very competently and successfully handled several lawsuits along with other legal matters and business transactions. Tim is a very bright and creative lawyer, is very thorough and he always gets successful results, even in difficult matters.

Solid Guidance

Tim provided thorough counsel and thoughtful analysis during times I needed help the most. In both a personal injury case and a dispute with my condominium board, Tim's steady hand and persistence made all the difference in getting the desired results.

Extremely Satisfied

Mr. Cerney represented me after I broke my arm in a slip and fall on a wet surface in a hotel parking lot in the Bahamas. The hotel's insurance company orginally denied my claim but Mr. Cerney aggressively pursued the claim and convinced the insurance company to settle. I was extremely pleased with the settlement. The entire process was handled in a very professional manner and I was kept well informed.

Best Attorney Ever

Mr. Cerney has represented my business in contracts, leases, litigation and several other matters for many years. In a difficult breach of contract case which Mr. Cerney successfully defended with a very creative argument, the judge stated that Mr. Cerney was "the most outstanding advocate that ever appeared in (his) courtroom".

Outstanding Lawyer

I own a small business and Mary Jo O'Donnell has been extremely helpful in our litigation matters. She has a great blend of pragmatism and aggressiveness, and has helped us pursue our contracted rights with very reasonable expenses and great results. She proactively offers suggestions as to a course of action, and effectively keeps tabs and communicates to us on multiple concurrent cases. She has been instrumental in helping us obtain recovery that otherwise we would never have received.

I have been so impressed by Mary Jo's skills in a business context that I decided to use her in a personal real estate transaction. In that deal, the seller and their counsel attempted to play some games. Mary Jo was extremely effective in responding to their moves and ultimately improved our terms. I would highly recommend her for any real estate transaction.

Mary Jo has a very friendly and disarming manner and is a pleasure to work with. She is also tough as nails and can be suitably aggressive as appropriate. She has an enviable combination of charm and assertiveness that is reflected in her strong desire to win. I recommend her very highly to anyone.

Excellent Law Firm

I own a hearing conservation technology business and have been represented by Tim Cerney and Carroll, Hartigan & Cerney since I started the business in 1985. Tim has handled many transactions and drafted numerous complicated contracts for my company, often involving joint venture and patent and trademark issues. He has always provided thoughtful, creative advice and guidance to me in growing my business. Tim has also obtained very successful outcomes for my company in several lawsuits, including a recent breach of contract/ confidentiality suit in which he obtained a very favorable settlement a short time after filing suit. 

Tim is very detail-oriented and thorough, is easy to communicate with, and always keeps me informed. I recommend him and the firm very highly.
