Attorney Sean M. Sweeney is a partner with Halling & Cayo, S.C. and has the requisite skills, education, and experience to help serve all of your legal needs in the Wauwatosa and Milwaukee area.
Sean earned his Juris Doctor (JD) and Masters of Business Administration (MBA) from Marquette University. He earned his Bachelor of Science degree in Business Economics from Northern Arizona University.
Before opening his own practice, Sean worked for the Milwaukee Bucks as a legal intern drafting and reviewing big dollar sponsorship deals. Sean has experience drafting contracts ranging from small business contracts to plow a parking lot to large corporation contracts dealing with operating and maintaining real estate.
Sean has not only the legal training and experience needed to provide complete service, he also has the education and training to understand the real world needs and challenges that organizations large and small face today.
Guardian Ad Litem's Office: While in Law School Sean worked for the Guardian Ad Litem's Office in the Children's Court. While there, he worked on cases involving Children in Need of Protective Services actions as well as Termination of Parental Rights actions. Sean also researched extensively and helped prepare for a Wisconsin Supreme Court case involving a Termination of Parental Rights action.
Milwaukee and Waukesha County Public Defenders Appointments: Tosa Law Office has represented clients as a Public Defender appointed Attorney in both Milwaukee and Waukesha counties. The public defenders office provides legal assistance to those people charged with a crime who do not have the means to pay for counsel on their own. Often times the Public Defenders Office is not able to adequately serve all of the people who need assistance, therefore attorneys such as Sean with Tosa Law Office take some of the surplus cases to help ease the burden on the often overtaxed public defenders office.
Big Brothers Big Sisters: Sean has been a Big Brother through the Big Brothers Big Sisters organization in Milwaukee since July of 2007. Sean has been placed with a little brother, Sema-j, Sema-j and Sean have had a lot of fun together and the experience has shown to be very rewarding for both Sean and Sema-j. As a personal recommendation, I would ask that anyone who has the time, (just a few hours a month) should sign up to be a big brother or big sister. I do not know of any other way to more significantly impact a young persons life than to simply take an interest and help teach them how to feel good about themselves and be successful in life. This request comes doubly for Men to be big brothers as there is always a shortage of Big Brothers vs. Big Sisters.

I have worked with Sean in complex mortgage litigation. Most new lawyers would shy away from involvement in such a case. Sean's manner with the client has been exemplary. He has taken hold of all the details and has involved me in the matter to give him guidance in areas of law and procedure. Sean's professional growth during the past year has been exceptional. He is much farther along in his professional development than his age and experience would indicate.

I met Sean through various legal listserves we are on together. I am always impressed with the quality of the answers Sean gives. It is clear he is very knowledgeable about his practice areas. He is also client focused. I definitely recommend Sean.
