Born in 1960, the son of a deacon, Father Gabriel-Allan was raised in an Evangelical Christian tradition and was trained to love the scriptures from the time he was a toddler.  After graduating high school, he immediately entered a Christian bible college in Lubbock TX, where he met his future presvytera, Danita, to whom he’s been married since 1981.  Shortly after their wedding, Father Gabriel-Allan found employment with Fleming Foods Grocery Wholesale Warehouse in Phoenix, AZ as a warehouseman and dock foreman, where he remained for 16 years.  Later, he went to work for Intel, in one of their semiconductor fabrication plants in Chandler, AZ, as a quartz-clean specialist, where he also served on their Emergency and Medical Response teams.

During this time, an Orthodox priest began sending books for him to begin exploring Orthodox Christianity.  That initiated Fr Gabriel-Allan's aggressive 6 year scrutiny of Orthodox theology, until finally, in 1998, he and his family requested to become catechumens in the Orthodox Christian Faith.     
After a further, year-long catechumenate, experiencing the entire liturgical cycle of the Church’s feasts and a series of classes, he, Danita and their two children, Joshua & Faith, were received into the Orthodox Christian Faith on Lazarus Saturday, 1999.

During his first several years as an Orthodox Christian layman, he served the Church in the roles of Altar Captain; Sunday School Teacher; Parish Council Member; and Radio Show Co-Host—doing Orthodox apologetics on a call-in Evangelical Protestant radio station. In 2003 Father Andrew Barakos, of Assumption Greek Orthodox Church in Scottsdale AZ, sent him to Hellenic College, to pursue undergrad studies and then a graduate degree.  During that time, his wife, Presvytera Danita, used her gifts to initiate a highly successful campus religious education program for the nearly 50 children of seminary students (something that the school had never had before). While still an undergrad, Father Gabriel-Allan also served for two years as president of the Married Student's Association for both Hellenic College and Holy Cross.  There, he and Presvytera Danita worked as advocates for campus family-life issues and the quality of life for the many children on campus. After graduating from Hellenic College with a Bachelors Degree in Religious Studies, in 2006, he began attending Holy Cross Greek Orthodox School of Theology to pursue his Masters of Divinity.  During his time with Holy Cross, he traveled to Albania with an Orthodox Christian Mission Center team.  For 2 weeks there, he worked in their Tirana summer-camp employing the use of folk stories to introduce

Muslim and atheist children and teenagers to the Orthodox Christian Faith.  In the summer of 2008, he spent several weeks traveling through Greece and Turkey, where he visited ancient Christian holy sites, including a 6-day pilgrimage through Mt Athos and a visit with His All-Holiness, Ecumenical Patriarch Bartholomew.  Over the course of his last academic year, Father Gabriel-Allan worked an internship with a street outreach ministry in Boston, helping to feed, clothe and connect the homeless and marginalized with both physical and spiritual resources. In March of 2009, he participated in the first, annual, Holy Cross Preaching Competition, where the school's faculty judges awarded him with the highest score.  After six years in Brookline MA, Father Gabriel-Allan graduated with a Master of Divinity degree on May 16th, 2009, and went immediately to serve Assumption Greek Orthodox Church, in Scottsdale AZ, under the guidance of Father Andrew Barakos, in the role of Lay Pastoral Assistant.

In March of 2011, His Eminence, Metropolitan Gerasimos transitioned Father Gabriel-Allan to Los Angeles to begin serving as St Sophia’s Pastoral Assistant.  On June 13th, 2011, His Eminence ordained Father Gabriel-Allan to the Deaconate, and then to the Holy Priesthood on July 17th, where he served as Assistant Priest to St Sophia Cathedral until November of 2015.  Under the wise mentorship of his Proistaminos, Father John Bakas, Father Gabriel-Allan helped pave the way for a widened demographic at the cathedral, where one can find people from many different cultures, ethnicities and religious origins, now adorning the community as Orthodox Christians like precious jewels.  Fr. John and Fr. Gabriel-Allan also teamed up on intensive efforts to guide the parish-council and the parish-at-large towards a greater awareness and fulfillment of the Church’s divinely given mission.  During his four and a half years there, Father Gabriel-Allan established a “WHYs of Orthodoxy” class, serving as both a class for those who wished to become Orthodox and a place where people who grew up in the Faith could learn more about why we Orthodox Christians believe what we believe and do what we do. During his term there, he also taught an introductory class to the Old Testament, illuminating the many passages so often referenced throughout the entire liturgical life of the Church. In 2013, he was additionally instrumental in starting an “Orthodox Young-Adult Professionals FORUM” ministry, where 20-35 people continued to attend weekly to share a meal together, pray together and strengthen their grip on tools from ancient Orthodox Christianity, to help them thrive in 21st century conditions.   

Father Gabriel-Allan and Presvytera Danita’s two children are now in their thirties.  Their son Joshua, a chanter in the Atlanta Cathedral, has given them a grandaughter and a grandson.

On December 1st, 2015, His Eminence, Metropolitan Gerasimos, assigned Father Gabriel-Allan and Presvytera Danita to begin making their home at Saint Basil the Great Greek Orthodox Church, in San Jose, California.  Being especially enthused by the solid foundation laid by the pioneering life and work of that parish’s namesake, Saint Basil, Father Gabriel-Allan looks forward to serving and shepherding this beloved parish family and helping to nurture an environment where people from San Jose can come to be transformed into Christ-likeness.
