Tom Harmon started his artistic career in 1964 after he retired from the United States Army.  While boating in Puget Sound he found that painting with watercolors was very rewarding and it was easy to take the materials with him on his boat.  Many subjects presented themselves, but the thing that caught his attention most was lighthouses.  Tom painted 26 lighthouses along the West Coast and had them printed into notecards. He then successfully marketed those notecards in the Pacific Northwest.

After moving to Mississippi Tom became associated with Very Special Arts of Mississippi in 2001.  He became the teaching artist and formed a group of artists with disabilities, which met in Jackson Mississippi. The group has now grown to over 30 students and meets weekly at the Mississippi Arts Center.

Tom has continued his artistic education and has attended many workshops and seminars. He now paints and oil and acrylic as well as continuing to paint in watercolor.

In 2006 Tom was awarded signature status in the Mississippi watercolor society.
