Advocacy for Clerics, Religious, and Laity
Too often, the rights of the faithful – under both canon law and even natural law – are not being observed, even by some in the Church. If you need an expert canon lawyer to help you vindicate your rights, please let me know. If you are a priest accused of misconduct, it is vital that you avail yourself of competent canonical counsel as soon as possible.
Parishes
Demographic tensions, financial struggles, and ideological differences can cause tensions within parishes and within dioceses. If your group needs an objective opinion or expert advice, I am here to help.
Declarations of Nullity "Annulments"
The process surrounding a declaration of nullity regarding a marriage can be confusing and painful. If you need an independent advocate to hear your story, please call.
Defamation Actions
Attacks on reputation are becoming more common – and more damaging – in this age of the internet and social media. If you believe that your good name has been harmed, I am ready to advocate on your behalf.

Frequently Asked Questions
Canon law is the body of norms that govern the Catholic Church. The time-honored principles of canon law help define and protect the rights and duties of the faithful, making sure that the Church lives up to the mission entrusted to it by the Lord.
A canon lawyer can help people in need of advice, assistance, or representation with any issue regarding the Catholic Church. This can include actions relating to defamation, declarations of marital nullity (“annulments”), fiscal mismanagement in a parish or diocese, difficulties within religious congregations, or issues relating to sexual abuse claims or abuses of ecclesiastical power.
As soon as someone’s canonical rights begin to appear to be threatened, the early involvement of a reputable, knowledgeable, and competent canon lawyer is absolutely critical. If you are a cleric accused of misconduct, you need to call such a canonist as soon as possible, as time is of the essence.
Civil lawyers are used to negotiating and problem solving. They also can be trusted to keep client confidences under the attorney-client privilege. Being familiar with both systems of law can be of tremendous assistance when helping clerics accused of misconduct.
