Michael Sligh

Obituary and Tributes to Our Late President

 

We are very saddened to announce the passing of our President, Michael Sligh, on Friday 7th November 2025, after a short illness.  Michael touched so many lives with his dedication to organic farming, his wisdom, his humanity, and his humor.  We send our deepest sympathies to his wife, Janet, and his whole family.

I liked Michael Sligh an awful lot.
We served on the IOAS Board together for more than 10 years and he is one of the most pleasant people I have ever worked with.

(Complete Tribute)

Michael was first and foremost a good friend to both Annie and me. He and Janet visited us for a few days early in the year. It was a wonderful visit with lots of laughter. 

Ken Commins
Former IOAS Executive Director

(Complete Tribute)

Michael has left us too early. He gave so much to IOAS and despite being officially ‘retired’, he still retained boundless enthusiasm and commitment to growing organic agriculture until he became ill early in 2025.

Consensus Man (by Jim Ford)

Michael liked to tie a bow
Michael had a plan
Michael was a listener
He sought consensus, man

Michael, The Farm’s farmer
Grew food for the world
Kept the soy crew stocked
While those around him twirled

Michael was a leader
With a gentle Texas drawl
His ear to the ground
Progress, even if a crawl

   Michael wrote the “Green Book”
Captured visions and ideals
Put it on the record
How the movement feels

Organic action plans
Fair and just good food
Meeting after meeting
To which others now allude
Michael loved the mountains,
His dear wife and family
He made the world a better place
Earth love his legacy
