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.

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.

Outstanding service & outcome from them on my business litigation case

I can't say enough about the service and outcome from Sean Sweeney and his team regarding my business litigation case. They went above & beyond staying focused with my various issues. The end result was exactly what I needed them for and if in the future I have any kind of issue I know I can count on them. If anyone else needs help with legal items I can't stress enough that Halling & Cayo will get their issue handled in the best possible way.
