With a deep sense of sadness, the Tyndale community mourns the loss of Dr. Don Posterski, husband of Dr. Beth Posterski, Professor Emeritus of Tyndale University College & Seminary. He passed away the afternoon of June 13 at the age of 76 after a short but courageous battle with cancer. Don was an internationally known Christian leader, speaker and author, who served for an interim period as the R. J. Bernardo Family Chair of Leadership at Tyndale Seminary.
Over the years, Don served in many ministry capacities, most notably for 16 years as senior leadership staff at the Inter-Varsity Christian Fellowship and for 17 years of distinguished service as a senior executive with World Vision. Throughout his vocational career, he demonstrated outstanding leadership capacities and effectiveness. Dr. Janet Clark, Senior Vice President, Academic Dean of Tyndale Seminary, once noted that his life and ministry had a “life-long focus on developing leaders.” At the same time, his astute capacities for contextual analysis, his research and communication skills, as well as his passion for justice formed a rich and distinctive experience from which to wrestle with the leadership issues of our time.
With President Gary Nelson, Don wrote a book entitled Future Faith Churches, a study on the state of the Canadian Church. Both authors held a passion for what the church could be in Canada and sought to nurture its voice and impact.
During her time here at Tyndale, Beth was an astute and strategic professor of education. She ushered in an enduring partnership with the Early Childhood Education program at Seneca College and wrote extensively on subjects in the area of education. Together, Don and Beth were a formidable force – Beth with her calm, assured presence and Don with his passionate willingness to speak frankly and honestly.
Please be in prayer for Beth and their family during this time. A service of celebration will take place here at the Tyndale Chapel on Sunday, June 24 at 4:00 pm, visitation with friends and family begins at 2:00 pm.
Those who knew him are invited to share in the creation of a memorial site by adding a condolence note and any stories, photos, and video clips appropriate to Don’s life. Simply follow the link.
