She treasured time spent together, around the table playing cards, laughing through game nights, and simply enjoying the comfort of family.Misty built deep and meaningful relationships wherever she went.

She had a remarkable gift for connection, forming friendships that were deep, lasting, and genuinely meaningful. Her kindness, warmth, and easy laughter drew others in, and she nurtured those relationships with care and sincerity. She held a special place in her heart for her “Golden Girls”, her fellow nurses, and her Bible study ladies–but every friendship was special and everlasting.Above all, she was a woman of strong and unshakable faith. The truth of the Bible, first instilled in her by her mother, guided her life and became her purpose—to share her faith boldly and give glory to God.
