Ivy Marie Humbert was born March 5, 1942 in Walden, Colorado to Dick and Phyllis Humbert. She joined her brother Richard Russell (Butch) living in Walden. In 1945 the family moved to California where Dick Humbert and his brother, Ralph (Curly) Humbert worked driving heavy equipment in the Napa Valley area. Initially the family lived in Sacramento, California, but moved to Saint Helena, California where Ivy attended kindergarten, then first grade. In 1948 the family moved back to North Park and began ranching on the current ranch purchased from Mary Alice and Fred E Brands, her grandparents. Ivy attended grade school starting with the Higho school on the West Side, then through the 7th grade in Walden. For the next grade she moved to Julesburg, staying with her aunt, Minnie Porter and Minnie’s four girls. After her 8th grade Ivy came back to Walden and attended Jackson County High School, playing clarinet in the band and serving as Drum Majorette in her senior year. Colorado State University was her next stop where she pursued a degree in Home Economics Journalism. While in Fort Collins, she married Wayne Leaming with whom she brought two daughters into her family. She later completed her course of study at Colorado State University in 1982. During her time in Fort Collins, she worked in several industries and wrote a column for the Fort Collins Coloradoan newspaper. She continued writing for the Coloradoan part time throughout her life.

Ivy was an active participant in Humbert Ranches, Incorporated, a family corporation founded in 1972, where she was a shareholder and firmly rooted in North Park.

In 1982 she married Frank Johnson, Jr., a farmer, from Julesburg, Colorado. It was here she found her calling. Frank and Ivy established the Joy Mission, using her middle name, legally changed. Both Ivy and Frank became pastors and followed Kenneth Copeland. Yearly conferences were attended either by travelling or by teleconferencing. Ivy wrote a monthly paper, the "Joyous Report", created many CDs and penned a book. Through the Joy Mission, Ivy reached out and mentored many individuals, including inmates in several institutions, often with successful results.
