Why am I passionate about being an Expert Witness?
Arrie Lee Johnson Portrait from 1971 with his Grandson
Charles McGilvary Johnson, PSP, FCP
Arrie Lee Johnson (1903-1983) was my hero, and my Grandfather. I only knew him for 13 years, but he was a larger-than-life character in my family hometown of Milton, FL. He was known as "Judge AL" by all in the area. I was raised in SC, but when I would visit as a young boy it seemed everyone knew my Grandfather. I would ask my mother, “who is this “Judge AL” they are speaking of”?
​
He was the eldest of 18 children, yes eighteen, born to a farmer in Evergreen, Alabama. From what we can tell they grew Sorghum, Corn & Cotton on a large tract of land. Today, Evergreen is still a 1 or 2 red light town in South Alabama (pop. 3,900) in the heart of Conecuh County. Conecuh is well known for sausage. Arrie excelled in school and made his way to the University of Florida Law School in Gainesville in 1928 at the age of 25.
We are not sure why he waited to attend school until the age of 25, it may have had something to do with paying the $320 annual tuition. The 343-mile trip from Evergreen, AL to Gainesville, FL in the mid 1920’s had to be one that took more than a few days. He graduated in 1931 with a Bachelor of Laws Degree and since there was no Bar Exam in those days, he immediately started practicing law.
​He married a young lady, Mary Burnham, from Bushnell, FL (not far from the present-day development known as The Villages). After graduation, they settled in Milton, FL, and started a family. He not only practiced law, but he also served as Santa Rosa County Judge from 1933 to 1944. I recently discovered he was a member of the Florida Bar Association (39674) from 1932 until he passed in 1983, over 50 years!
​
For years we have heard stories from friends and distant relatives about how helpful he was to people in the community and family members, whether distant or close. It was not unlike him to provide free legal services, even bartering at times with local shop owners or farmers. He was also generous with his money, for those that were truly deserving and humble. One can easily imagine his generosity was impacted by his upbringing in Evergreen on a farm with 17 siblings where things were… not plentiful. His heart was big, but he was stern and demanded you behave, especially a grandchild of his. I can still hear his rich & thick South Alabama/Northwest Florida accent. If you know it, you know it.
​
He had a dry sense of humor, a very thick sarcasm, but we knew we were loved, even though he never said it. They didn't in his time.
​
The photo you see above is a Painting/Portrait of Arrie Lee Johnson that he sat for in 1971. It hung in his office for decades. In January 2009 it survived a major structural fire in Milton, FL and after I acquired it, I had Leon Loard Studios clean it of soot and water damage and restore it properly. It is one of only a few photos I have of my Grandfather.
​
“Judge AL” Johnson is why I have chosen to offer Expert Witness services to my clients. My Grandfather helped people, from all backgrounds, whether you were able to pay for his services or those less fortunate who couldn’t pay. I have learned a lot in my 30+ years in the Security Industry, and this is the closest opportunity to emulate him and provide my knowledge and assistance to those involved in a Negligent Security, Personal Injury or Premises Liability claims or lawsuits.
​
I hope “Judge AL” is proud, I know I am.
