The Armstrong Family is Judge Armstrong's most treasured achieve-ment.

Mona has been married to her husband, Todd, for over 20 years. Todd serves the citizens of St. Clair County as a Parole/Probation Supervisor for the State of Michigan. After he completed law school in 2004, Mona presented the motion to admit Attorney Todd Armstrong to the Michigan Bar. 

Todd and Mona reside with their two children in Fort Gratiot Township. 

Their daughter Alysse, age 18, graduated from Port Huron Northern last spring.  She now attends the University of Michigan.

Their son Alex, age 15, is also a proud Husky at Port Huron Northern. He is active in basketball, football, and baseball.

For twenty-five years no victim, particularly vulnerable children, had a better friend and advocate than Mona Armstrong. 


Time and again she has been trusted by her superiors to handle the most heart-wrenching and high-profile prosecutions in St. Clair County history.  


Judge Armstrong gained a reputation as a tough, “no nonsense” prosecutor.  That is true for the murderers, abusers, and rapists she prosecuted.  What the public did not see behind the headlines was her heartfelt compassion toward rape victims, abused women, molested children and the surviving loved ones of murder victims.

A career spent prosecuting the worst predators in St. Clair County history also meant consoling countless victims and their loved ones.  Many of the young people Judge Armstrong has helped throughout her career are now adults, working and raising their own families in our community.  Judge Armstrong helped them gain their voice and achieve justice. 

Judge Armstrong has also exhibited that kind of compassion in hundreds of District Court matters over her twenty-five year career.  

These experiences uniquely position her to understand the circumstances of the parties appearing in her courtroom.  These experiences gave Judge Armstrong the kind of compassion and empathy that does not come from merely observing things in court, but from actually advocating in court.
