Our Culture

While we staff three offices in southeastern Wisconsin, our main office is a converted warehouse in Milwaukee’s historic Third Ward. We like to think our office building represents our firm’s culture well. In the same way our building’s architect took an “out of the box” approach to repurposing this old, stiff building and has given it new life, we’ve similarly decided to reject the typical rigid conventional law firm model. Friendly and informal, we’ve chosen a flexible and personal approach to our internal organization. Our structure permits us come up with innovative arrangements with our clients and gives us the freedom to provide cost-effective and goal-oriented solutions while still keeping our legal services of the highest caliber. Time and time again our clients have remarked at how surprised they have been with how easy we are to work with.

If you would like to consult one of our friendly, expert Milwaukee attorneys about your present legal matters, please don’t hesitate to contact us today.

Excellent Legal Representation

My experience thus far with the firm and particularly, Sean Sweeney has been outstanding! Although we have yet to move the case forward officially, I have nothing but great things to say about the advice and service.

Exactly what I needed to proceed on my FINRA Claim

I'm very grateful for the time that Mr. Schaalman so generously, kindly, and freely gave me in our initial meeting. His relevant examples were vivid and memorable. I felt energized and equipped when I left and actually did start writing my Amended Claim right away, incorporating the points he made. His advice was excellent. I'm so thankful, and if I proceed in my Claim, I feel confident that Mr. Schaalman will be the right one to help me further.

I want to tell anyone who is looking for a great attorney, look no further than Ryan Harrington of Halling &Cayo. He takes the time to know every aspect of a case and when he spoke to the judge in court his knowledge of our case was evident and what we wanted to accomplish was understood and granted thanks to him. Confident, fair, thorough and a very nice person..THANK YOU!

I am a client of Sean for few years and I am impressed with his work but most importantly with how caring he is about someone elses problems.I have also worked with others in that office and I would recommend these lawyers to anyone who is lost and needs guidance. Each one of them is helpful, professional and always available.

Trusted Advisor

Sean Sweeney & his team became a trusted advisor to me and my family by providing a valuable service to our needs. He exceeded expectations with his ability to act prudently and swiftly when called upon. I’m happy he’s on my team!

Caring and talented attorneys

I had been the victim of an unqualified financial advisor and lost nearly half of my retirement savings. Attorneys Michael Schaalman, Patrick O'Neill and Olivia Fitzgerald helped me get my money back. I am bordering on elderly and would never have been able to recoup my losses on my own. The education they provided me and the dedication to my case were more than I had hoped for. I will forever be grateful for their help.

Amazing Attorney

Sean Sweeney has helped us in so many ways that we can only say that he is nothing short of fabulous . From employment situations to business formations and much more, he has provided us the counseling and care that was above and beyond all we could ask. If need arises, we more than highly recommend, and will always turn to our attorney, Sean Sweeney.
