Thank you, Mr Leininger
Divorce is not fun for anybody ever going through it. I was no exception. Having Bill Leininger by my side made the whole process much easier. I'm a medical professional and expect from attorney what patients expect from me. Experience, availability, knowledge, and prognosis. Mr Leininger was at the top for each category. And the most important. Years after that bitterly process, me and my ex wife on the friendly terms and children are happy,

Great Lawyer
Mr. Leininger has been there for me when ever I needed him. I remember calling and speaking with him at the very last minute for my first court appearance and he made me meet him at his office the very next morning and drove me to court with him. Over the time of all aspects of my separation and divorce, Mr Leininger was always right there for me to answer any and all questions I may have had. He was always prompt to court and always prepared for my case. He would even call me and see how I was doing "off the record" and over time I considered him a friend and not just my attorney. Mr. Leininger would always keep me up to date on any news on my case either threw a phone call or a text or an email or a meeting at his office. I was always very confident in Mr. Leininger watching out for my best interest and helping me through the toughest time of my life.

a specialist on your side
During the most trying period of my life, My head was clear enough to know who and what to ask when decicding who I would allow to represent me.While there were hundreds of attorneys to choose from, I do not believe I would have recieved the same level of service in any other office. I am so happy I made the decision and investment to have Mr. Leininger on my team !!

Divorce and separation Attorney | Apr 01
Relationship: Fellow lawyer in community
"I have had many cases with William Leininger over the last 25 plus years and all I can say is that he is a no-nonsense, straight forward attorney with great skills and I recommend him highly. As a fellow attorney, I would retain him myself, if I we're going through a divorce. He is particularly adept at avoiding unnecessary litigation with his knowledge of the law which ultimately reduces the cost his clients will expend in their divorce actions. Knowledge is power and that fact is certainly exhibited in the way he practices law. Highly Recommended."
