I and my children my grown children miss this dear man. He was not only a friend but a very trusted doctor with a great sense of humor. Can't find a doctor I trust as much.

He was the kindness doctor I ever went to. He was also one of the best friends my dad Phillip Spence had. Dad built things for the Doctor, either at his office or at his home where ever it was at the time. He took care of us while we were growing up. And then when it was time to have my baby girls he delivered them both, one in 1973 and the other in 1976. I love him still. I know he will be sorely missed.

Doc was more than just a doctor to my family. My father Phillip Spence loved him like a brother. In fact our whole family love this man dearly. My father built his A Frame cabin and then his log home on his property. Doc will be surely missed.

Your family is in my thoughts and prayers. Dr. Sisler was my Dr. in high school and Jr. High. I will always have fond memories of him and his practice. May he Rest In Peace.
