Our Clergy


The Reverend Pierre-Henry Buisson


Born and raised in a France, Father Pierre-Henry was ordained a Roman Catholic priest by his bishop Jacques David, in the St Pierre Cathedral of Saintes, on April 29, 1990. Before he was ordained he served six years in the French Army, as a sergeant, and attended the Seminaries of Poitiers, and Bordeaux. After his ordination, Father Pierre-Henry was sent to the parish of Mirambeau, France, as associate rector. He knew the parish very well since it was his Field Ed. parish for 3 years, he was especially in charge of youth and children ministries. After serving the parish of St Genis de Saintonge, in the same area, he became the Rector of Archiac.  On September of 1996 he resigned his position of rector and asked Sophie for her hand in marriage.

He became an employee of an energy company, Gaz de Bordeaux, where he served in various positions, from working to the mail office, to being a customer agent, and a purchasing agent.  He could not hide his past, and even if he did not belong to any church at that time, he was a kind of ‘bi-vocational’ priest to whom people could confide and ask questions.

He discovered the Episcopal Church, and the Anglican Communion in April 2000 after the birth of his second child, Pauline. In 2001 he was received in the Episcopal Church by Bishop Jeffrey Rowthorn, and started with his wife the French Speaking Mission Saint Martin, in Bordeaux.

In January 2003, he was received as a priest by Bishop Pierre Whalon, and in March 2003, when his 3rd child Clement was baptized, he officially became the Priest-in-Charge of the Mission St Martin.

In 2008 Pierre-Henry, Sophie, Raphael, Pauline and Clement moved to Alexandria, Virginia. Pierre-Henry studied at Virginia and received his Master of Theological Studies in May 2010. After graduation, Pierre-Henry accepted the call to be the Assistant Rector of St Martin’s in the Field, in Severna Park, MD. He was also the Chaplain of St Martin’s Episcopal School where he had the joy to teach and celebrate weekly chapel services.

Deacons belong to one of three historic orders of ordained ministry—Bishops, Priests, and Deacons. In the Diocese of Arizona, Deacons serve in a parish setting by mutual agreement of the Bishop, the Rector, and the Deacon. All of them assist with leading worship, occasionally preach, and offer significant pastoral ministry. In addition, each is required to have a ministry that helps to make connections between the members of the parish and the community in which we live. The Deacons serve without financial compensation.

She has currently been assigned as Clergy Oversight for Pastoral Care where she is intently working to bring the church to the homebound and those living on the fringes in our society.


The Rev. Keehna Sture 


Because Keehna’s world operates on kairos time, her life has not been measured in years, but rather in her response to the question God poses to each of us—a question so beautifully articulated in one of Mary Oliver’s poems: “Tell me, what is it you plan to do with your one wild and precious life?” Keehna has spent hers in service to others, not just in one profession, but in several, each of which contained seeds of the one that would follow: social worker, nurse, nun, missionary, social justice advocate, prison counselor, companion to the dying, and supporter of the grieving.

The second oldest of ten children, Keehna was raised in an Air Force family. Her father was an oral surgeon, and her mother was a miracle worker who, besides “keeping the home fires burning” every day, would oversee the practical aspects of moving 12 people, every three years or so, from one State, or country, to another. Through her family’s travels, Keehna learned that home is everywhere, and that the world is inhabited not by strangers, but by friends we just haven’t met yet. The “travel bug”vhitched a ride into her adulthood—and, by now, the places she’d still like to see are far
outnumbered by the places she’s already been.

Intending to retire, or at least slow down, Keehna moved to Arizona in 2016, but it wasn’t long before she discovered that God had other plans for her. Sensing a call to Holy Orders, she spent the following year in discernment—a formal process which helps the Church to determine if it, too, hears the call that the aspiring deacon is hearing. Receiving that affirmation from the Commission on Ministry in 2018, she and her classmates began a two-year formation program of academic studies, ongoing discernment, retreats, pastoral care training, liturgy practicums, and a six-month
internship, which, for Keehna, was served at St. Thomas Episcopal Church in Clarkdale.

In May, 2020, in the midst of the COVID-19 pandemic, she and one of her classmates were ordained to the diaconate by Bishop Jennifer Reddall, in a liturgy that conformed to Phase I CDC guidelines: everyone work masks; social distancing was observed; and there were just ten people present. The experience was stark yet sacred—and a reminder that, even in the worst of times, God’s work goes on.

As the pandemic continues to reshape so many dimensions of Church life and the living out of our baptismal vows “to seek and serve Christ in all persons,” and “to strive for justice and peace among all people,” it’s not surprising that “flexibility” is the most common word in Keehna’s vocabulary right now. Her ministry as a chaplain at the Arizona Pioneers’ Home is on hold due to the “no visitors” policy currently in place at all care facilities across the State, so she is helping out with Sunday online worship services, pastoral care, and discovering new ways, from home, to be Christ’s hands, and feet, and heart, in our wounded world.
