About Jack

Learn Jack’s areas of practice.

I have been practing in the area of family law primarily for 23years.   I concentrate my practice on representing individuals going through dissolution and paternity matters as well as Motions to Modify cases in the State of Missouri.  I practice in St. Charles, St. Louis, St. Louis City, and Jefferson County.   My goal is to work with clients on a one-on-one basis to get them the best results possible.   Client involvement is important to me because it gives me the best opportunity to get to understand the case and needs of my client as we work through their case.  The other portion of my practice is estate planning.  My goal in the area of estate planning is to provide my clients with effective solutions to their estate needs at a reasonable price.

Highly Recommended
Jack has been wonderful to work with, both times I used him. When I first used him in 2008 for my custody case he was beyond helpful. He explains things in a way that are easy to understand, but even better than that, he listens. There were many times when I wanted to make extraordinary demands and Jack was able to walk me through things and give me a better idea of how to approach things. In 2018 when it was time to revisit my original case it was a no brainer to use Jack again. He is professional and personable at the same time and always helped me feel good about my decisions moving forward.

Honest and Excellent Service
This attorney treated my situation with grace, understanding, and compassion. He was professional, courteous, and honest. He handled a painful case with a firm understanding of the law, and was more than ready to tackle the issues with a realistic and upbeat attitude. He bent over backwards to accommodate my work schedule. I would recommend his services to anyone.

Jack is amazing and helped me get sole legal and physicalcustody of my son
Jack has represented me for over two and a half years in St. Charles County, Missouri. He got me sole legal and sole custody of my son with my ex-wife receiving supervised visitation. This case was extremely difficult because essentially my ex-wife had four psychiatric breakdowns with psychosis during the pendency of case. The case required a custody evaluation and a second custody evaluation by the psychologist because my ex-wife continued to be institutionalized throughout the case. She would disappear for periods of time around the country, she was appointed her own guardian in the case ultimately because of her lack of mental stability. Jack worked vigorously throughout case to protect my interest and above all else my son's best interest. People have no idea how long a divorce with problems can take, but Jack was with me through the whole ordeal. I am very grateful to him and his representation and would highly recommend him to anybody going through a divorce or paternity case, whether simple or complex. You really know someone when you are in the trenches fighting and I cannot say enough good things about Jack as a person and a lawyer.

Great attorney
Jack represented me in my child custody case in 2017. He did a superb job preparing me for the case and provided exceptional professional guidance throughout the whole process. He kept me well informed and always ready for each and every step of the whole process.

Very Understanding and Compassionate. Tough Litigator.
Jack was my attorney in a divorce back in 2009. I was scared to death and Jack could see that in our first visit. Jack did a great job in comforting me and being empathetic. He did a great job in calming me down and explaining all my options. He also has a great network of professionals that he works with who specialize in areas of practice that touch what he does. Jack will be hones with you. He will tell you what the law says very clearly and succinctly, he will prevent you from making matters worse, and he will be honest with you.

GREAT lawyer
I used Jack as my attorney in my divorce a few years back. I first hired another lawyer which did absolutely nothing for me. I contacted Jack in them middle of my divorce and hired him to represent me. A family member of mine had used him twice in a custody battle and highly recommended him. He is very efficient and really works for his clients best interest. I was very young and having a hard time with my situation, Jack was attentive to my feelings and had my best interest at heart. I refer him to any friends and family that are looking for a great attorney. He is now what we in my family call "our family attorney"

Have used him twice with great success
I noticed a review by "Sue" with the title "great lawyer with a big heart". She really captured it. He is extremely astute, and that quality plus his finesse did a lot in overcoming the pomposity of my opponent's lawyer. He is great at looking for solutions. I really wish I had known about him years back when I was going through a very nasty divorce, where I got creamed. I very highly recommend him.

lawyer with a big heart
Jack is a great lawyer with a big heart who helped us to correct a child support and alimony case. He worked with us well even though we live out of state. We did come to Missouri to court once to resolve the matter.

Family Attorney | Dec 15
Relationship: Fellow lawyer in community
"Jack and I have both been practicing pretty exclusively in the area of family law since the beginning or our careers more than twenty years ago. In the high stress, detailed and demanding area of family law, I have always found Jack to be a calm, informed, prepared and ethical attorney. We have been opposing lawyers on some cases and these characteristics were consistent then as well. Jack is one of a small set of family lawyers who are truly "organic" in their approach to cases; never losing sight of the fact that there are people, emotions, sometimes children, involved and takes very seriously his role in finding resolution for the client in any situation. Jack is also well versed in accounting and business issues which is needed in high asset cases. I would highly recommend Jack."
