Mary Kay McCormick

May 1, 1956April 6, 2019

Mary Kay stepped from earthly to eternal heavenly life as promised by her Friend, Lord and Savior Jesus on Saturday evening, April 6, 2019, after nearly 63 years of mortal life. Her body was crushed by rare Erdheim Chester Disease (ECD) but her spirit soared in faithful confidence and assurance that Jesus has gone ahead to prepare a place for her with our heavenly Father (John 14: 2-3).

Mary Kay was widely known in the medical administration community in the Simi Valley and Conejo Valley areas for nearly 30 years for her love, joy, peace and patience toward others and her competence in her work. No matter what she faced in this life, she had a positive, Christian outlook and kind responses that placed others before herself.

Among the many who still linger and look forward in faith to a glorious eternity with Jesus, with Mary Kay and with other believers are her parents Lee and Geneva McCormick; her son Will Ruble and his wife Susan, grandsons Blake, Jaxson and Cameron and granddaughter Ciara; sisters Sue Thomas, Diane Woods, Denise McGill and Carolyn Williams and families; brothers Roger, Richard and Donald McCormick and families; beloved aunts, uncles and cousins; and a host of local friends and co-workers – all specially dear to her.

Mary Kay knew that Romans 5: 1-11 was for her and for all of us: “Therefore, since we have been made right in God’s sight by faith, we have peace with God because of what Jesus Christ our Lord has done for us. . . . God showed His great love for us by sending Christ to die for us while we were still sinners. . . . So now we can rejoice in our wonderful new relationship with God because our Lord Jesus Christ has made us friends of God.”

Celebration of Life services will be held at Pierce Brothers Valley Oaks-Griffin Mortuary, 5600 Lindero Canyon Road, Westlake Village, CA, on Saturday, April 13, 2019, at 2pm and at a later date in Missouri.

Dear Mary Kay,
Daddy and I are so lonely and sad without you since you went to Heaven. We know you are not suffering now and that you are with Jesus.
It is hard to find adequate words to express all we are feeling, but the scripture that has come to mind is Rev. 14:13. Then I heard a voice from heaven say, "Write, Blessed are the dead who die in the Lord from now on. Yes, says the Spirit, they rest from their labor for their deeds will follow them."
We loved you more than you could ever know,
Mom and Dad

My Dearest Sister Mary Kay,
Some may think you lost your battle with this terrible disease, but you didn’t. You won! You faced this challenging disease the same as you did the many hardships in your life, with the grace, courage, dignity and strength that can only come from knowing the Lord.
You have overcome the whole world (1 John 5:4-5). You chose a relationship with Jesus Christ, the most important gift of all, and therefore gained what you could never lose.
So now you are walking on streets of gold where "eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. " (1 Cor. 2:9)
Our family here on earth will never be the same without you, but it is at this time in the midst of my overwhelming sorrow and grief that I turn to 1 Cor. 15:55 "O death, where is thy sting? O grave, where is thy victory?"
Missing and loving you until we meet again,

Mary Kay was a beautiful lady both inside and out. She never complained of her continuing pain. She always ask how she could pray for you. Always thinking of others. I think of her now in the arms of Jesus and pain free. I look forward to seeing her in Heaven. I will miss her so much. I'm sure Jesus said to her. you have fought the good fight, you have finished the race, you have kept the faith from 2nd Timothy 4:7 and well done good and faithful servant. I loved her like a sister.
