Manchee was born in the small Southern California coastal town of Ventura in the late 40's. Bicycling, hiking, camping, fishing, traveling, baseball and tennis occupied the bulk of his time when he wasn't attending school.
He attended Buena High School, graduating with honors in 1965. During this time he became an Eagle Scout, earned the God and Country Award and was a Congressional Intern for Congressman Charles M. Teague.
Determined to become a lawyer and go into politics, Manchee attended UCLA majoring in political science. It was a tumultuous time with the Vietnam War raging and anti-war protestors running rampant on most U.S. campuses. During the California primary elections in 1968 Manchee went to the Ambassador Hotel to see Bobby Kennedy. Although a republican, he was intrigued by the Kennedy mystique and wanted to see it first hand. Instead he witnessed the aftermath of the Kennedy's assassination, watching Sirhan Sirhan's arrest and seeing Kennedy loaded into an ambulance.
After marrying his high school sweetheart, Janet Mello, in 1969 he moved to San Diego for one year while he attended the University of San Diego School of Law. After a brief duty in the United States Marine Corps which was the inspiration for his novel, Undaunted, he moved to Plano where his wife and two children were staying with his in-laws. He immediately transferred to SMU Law School to complete his legal training.
While in law school he and Janet both worked full time to support their family that had grown by then to six. In his spare time, Manchee was active in the Republican Party becoming Collin County Chairman in 1974-1976. This was the era where the Texas Republican Party was a small but growing minority party. During his tenure the party elected its first county officials including the Sheriff, a JP and county commissioner. Disillusioned by political back stabbing and opportunism he withdrew from politics in 1976, deciding instead to concentrate on starting his new law practice and raising his children.
After graduating from SMU Law School and receiving his Juris Doctor degree in 1976 Manchee worked for an insurance company for about six months before starting his law practice in Carillon Towers in North Dallas in 1977. His practice started out primarily in estate planning and business but soon bloomed into a general practice catering to the needs of the small business owner. After five years he moved to present location in North Dallas' Park Central. He practices today with his son, Jim.
Manchee's literary career began in 1995 when he started writing as a diversion from his stressful law practice. It wasn't long before he realized writing was his true passion in life. Since then he has written fifteen books. He plans to publish at least a book a year for the rest of his life.
