EXCEPTIONAL attorney in WILL COUNTY

Posted by

Erin is the most understanding, compassionate attorney I have ever dealt with. Due to the nature of my job, I know a lot of attorneys, and Erin is by far the most professional attorney I have ever met. She is not only intelligent; she is by far the most detail oriented attorney I know of. The end result of my case was ruled in my favor, but even if it hadn't gone in my favor, I would most definitely recommend Erin. She is very attentive, knows the law, and will make time to talk through everything with you. Her staff is absolutely exceptional as well. I can't say enough good things about Erin and her staff.

Excellent Family Attorney

Posted by

I can’t imagine a divorce ever being a good experience, but Erin worked hard to make a bad situation as good as possible. Her practice is small and specialized, so she can give her clients the attention they deserve. Erin was always quick to respond to email and phone questions. She knows her stuff too. When it was time to make a decision, she would thoroughly explain all of my options and the possible consequences of each. Her sound recommendations were made based on her knowledge of the law, the judge assigned and her “legal opponent.” By hiring Erin and her firm, I believe I got the best result possible. I certainly hope never to have to use her services again, but I would certainly recommend her.

Extremely Impressive

If your looking for a great Lawyer, who is very knowledgeable and works for the best outcome for you, Erin is for you. She is very professional and always kept me informed all the way through this difficult time.I have recommend her to several of my friends. She was the best choice and i am very happy with my results. Thanks Erin

Very impressive!!

Posted by

If you are looking for a detailed oriented go getter, look no further. Erin reviewed my agreement that was written up by my soon to be ex- wife's attorney. In short, she read every word of my agreement with passion to help me. She read through the standard language that I was expecting to pass through. She is so detailed orientated that she not only found wordage of great concern, she also found grammar and punctuation problems. If you are looking for an attorney to get things done right, set up a consultation with Erin and see for yourself. I believe you will be as impressed as I was. My only wish is that she practiced other areas of law. Thanks again Erin! Jimmy

Hard work achieves good results

Posted by

If you need an attorney who is hard working, attractive, tall and maintains herself in court with poise and dignity while still conveying a sense of conviction, it would be wise to contact Erin Webster O'Sullivan. Erin is committed to providing first rate legal service to her clients. She will stay in touch through emails and will return phone calls. She is kind and attentive to a client's needs. Further, she will be honest in guiding her client through the legal process. She also expects her clients to work with her while she handles the finer points of a legal case. Erin is patient, willing to compromise to achieve a good result. Best of all, Erin follows through on her commitments. Without fail, she will ask for client approval of every single step in fulfilling her obligations as an attorney to reach a successful conclusion in each case. Another satisfied client, Daniel

Erin was very considerate of the special circumstances in my case. A few other lawyers I spoke with just wanted to give me standard answers,didn't really want to go "the extra mile." Erin did,and it made a huge difference in a difficult time. She is a pro!!

Do yourself a favor and HIRE ERIN!!!

Posted by

I didn't plan on hiring a lawyer. I filed pro se and had to hire one when my ex went and hired his. After looking and asking around, I decided to hire Erin. BEST MONEY EVER SPENT!!! My ex's lawyer was one mean s.o.b and fought me on every issue, trying to delay the process and get me to concede a number of things. Erin fought for me and my kids and our best interests all along the way. Either she or one of her staff answered every question in a very timely manner, thoroughly so I could understand it, either via email or on the telephone. No question was left unanswered or treated as stupid or unimportant. They were all so supportive and caring that it made the worst time of my life much better. In the end, she helped me get a settlement that was better than I had originally counted on. I've had a great many issues and problems with my ex in the almost 10 months since my divorce. Erin has stepped up and assisted me with getting them settled. (Yes, for a fee!) Having Erin and her staff on my team made me confident and comfortable throughout the process and continuing. If you're looking for a lawyer in Will County, I can't say any more than I did above - hire Erin! You won't be sorry!!! Not many people can say they 'love' their divorce lawyer, but I sure can and do as often as I get the chance. Thanks Erin, Jessica and Arielle!!!!

EWO got it done

Erin was the only good part of my difficult divorce. She is a dynamite attorney - pragmatic, no nonsense and efficient working through the key issues. She listened to my concerns, understood my priorities and made sure my best interests were addressed. Some other attorneys seem work with their own agenda and don't take the time to listen. Erin helped me navigate through a tough time in my life and I can't thank her enough.

In my experience as opposing Counsel, and as a fellow Lawyer in the community, I have discovered that Erin Webster O’Sullivan is an extraordinary individual. She is highly intelligent, most competent, exceptionally professional, and wise beyond her years. Given the context of our practice in family law, I find it a delight to work with Erin because I know that she is interested in the equitable, reasonable, and expeditious resolution of her Client’s issues. Therefore, I hereby give Mrs. Erin Webster O’Sullivan my very highest recommendation.
