My practice focuses on wills, estates, trusts, and probate, helping clients get their final affairs in order and navigate through probate court, will and trust challenges, or trust administration. As much as possible, I help my clients and their families avoid conflicts through comprehensive estate planning, probate-avoidance techniques, powers of attorney, and pre- and post-nuptial agreements. My approach is to limit emotionally draining and expensive legal battles while assuring that your interests are protected.

Estate Planning

Not every plan is right for every family, and no two sets of circumstances are identical. By learning about your assets and goals, I can help educate you about the pros and cons of each estate structure.

I can craft an estate plan that will let you rest easy knowing that your affairs have been taken care of. As part of your overall plan, I can draft documents such as Wills, Lifetime Revocable Trusts, Testamentary Trusts, and Marital Property Agreements.

In addition, I can help you put in place a Powers of Attorney for finances and healthcare. These documents let you appoint someone as an agent who can make decisions on your behalf if you are unable to. If you do not have an agent who is able to make those decisions, you can use a Living Will (also called a Directive to Physicians) to instruct your doctors about how you would like to be treated.


Finding yourself in control of a loved one's estate and assets can be a daunting task, especially if things were not organized very well or if there are tense family dynamics.

I can help you sort through the all the paperwork and determine whether it will be possible to avoid probate court. I will also work with you to help keep the peace through a time that can be very emotionally demanding.

If probate is necessary, I can draft all of the required documents and deal with the court on your behalf so that you can focus on more important things. I can help you understand the terms of a will or trust and explain the rights and responsibilities of the personal representative, trustee, beneficiaries, and anyone else named in the trust.

Some assets - such as life insurance proceeds - may not go through either the probate or trust processes. Especially with older policies, it may be hard to figure out how to claim these benefits. I can track down the information you need to file a claim so that the proceeds can be distributed quickly. This will let you and your family collect the proceeds that you are entitled to without having to take time out of your busy schedule.

How did your firm decide on the primary area of practice(s)?

All of my fields of practice - divorce, probate, and estate planning - deal with families in crisis. I can help you navigate the legal, emotion, and interpersonal challenges that may arise, whether you are planning ahead to help avoid problems by using documents such as a trust or a marital property agreement, or if you are in the thick of dealing with a death in the family or the dissolution of a marriage. I am skilled in dealing with these contentious and emotion-driven situations, which is what led me to practice in these areas.

What experience or education distinguishes your lawyers from others?

Unlike many other divorce attorneys and estate attorneys, my education and training in law school did not focus on litigation. Instead, I focused on mediation and other types of dispute resolution (I learned litigation hands-on working as an associate after graduation). This focus on negotiated resolution was intentional, because 90% or more of all cases in these fields end in a settlement rather than a litigated court order. My training allows me to find solutions that other attorneys might miss, and to see important opportunities and common ground that allow for agreements that are more satisfying to all parties involved. I have found that poor agreements often leave one party angry and upset, which usually makes for more litigation down the road.

What distinguishes your law firm from others?

I understand that navigating the legal system can be an overwhelming experience. I believe that a lawyer should provide peace of mind as well as excellent legal advice.

I will listen carefully to ensure that I fully comprehend your situation and what matters most to you. I will provide you with all of the information you need to feel comfortable and confident with your decisions. Whether you need help starting a new beginning or navigating an end, I will be there to help you put all the pieces together.

I truly care about my clients and I want to help them navigate difficult and stressful times with as little friction as possible. I believe legal success and peace of mind go hand in hand.

Before opening my own practice, I worked at several other firms, including a small family-owned office, a medium-sized multi-attorney general practice firm, and high-end firm on the top floor of an office building in downtown Milwaukee. I learned a lot from each of these experiences and was motivated by the successes of those I worked with to venture out and design a business that matched my own vision.

I received my law degree from Marquette University Law School in 2010. I focused my legal education on estate planning, dispute resolution, mediation, and restorative justice. While at Marquette, I founded and served as the President of the Restorative Justice Society. I also served on the boards of the Alternate Dispute Resolution Society and the Client Skills Board. I was inducted into the Pro Bono Society with high honors for outstanding volunteer involvement with the Volunteer Income Tax Assistance Program and the Milwaukee Foreclosure Mediation Program. I also mediated small claims disputes at the Milwaukee County Circuit Court.

I received my undergraduate degree from Marquette University in 2005 with a triple major in English Composition, Philosophy, and Comparative Theology. I live in Wauwatosa with my wife and three children.
