Born on Oct. 22, 1949 in Troy, N.Y. to his physician father and socially active mother, Mac attended public schools through the fifth grade, then a military academy through middle school. At 13 he was off to an Episcopal boarding school (Trinity Pawling), and then on to an Episcopal College (Hobart and William Smith 1968-1972). 

His childhood was marked by physical activity and sports. Soccer in the fall, hockey in the winter, and lacrosse in the spring; these were the love and passion of his youth and adolescence. He also had the blessing of a healthy church foundation. His family attended St. John’s Episcopal Church every Sunday (like it or not), so he was raised within the Christian narrative.

After college graduation, Mac began his first career as an authentic American recreational fanatic, aka: ski bum.  He lived and skied for many years in Colorado and Utah before returning to the East Coast to care for his father, who since had retired to Florida. While there, he began attending St. Mary’s Episcopal Church in Daytona Beach and quickly became very active there. He was soon to meet his wife, Sandy, discern a call to ordained ministry, and, after the passing of his father, head off to Seminary in Evanston, Ill. During his Middler year, their daughter Biz hit the planet.

Mac returned to Florida to begin his Priesthood as an Associate at St. James’ Episcopal Church in Ormand Beach, where he served for five years before being called to Grace Episcopal Church, St Helena in 1993.  Twenty-four years later, retirement set him adrift until he hit shore again at St. Luke’s in Calistoga, which continues to be one of the greatest blessings in his life.

Janet graduated from San Francisco State University with a Bachelor of Science degree in Business Administration with a concentration in Marketing. She immediately started to work in San Francisco advertising agencies and stayed in that field for about seven years. She then changed sides of the desk and began selling commercial printing to the advertising agencies. Feeling constrained by the printing equipment owned by her employer, Janet started her own printing brokerage firm, enabling her to produce projects nationwide.

In 1980 she met Lowell Herrero, an advertising illustrator with art talent far beyond the commercial jobs he was illustrating. Janet and Lowell became partners, both in marriage and in business, and Janet became the business/marketing arm of Lowell’s new fine art business. The collaboration was wildly successful, allowing them to build a home and studio in Calistoga and move away from the hectic life of San Francisco.

Janet is now a widow, but she continues to market Lowell’s art through reproductions and licensing. She followed the Rev. William “Father Mac” McIlmoyl to St. Luke’s Episcopal Church in Calistoga and his preaching has inspired Janet ever since. She now serves at St. Luke’s Treasurer.
