Dr. David Keast

KEAST, Dr. David…

David passed away peacefully with family by his side at University Hospital, on Wednesday, August 19, 2026, a day short of his 81st birthday.

Dr. David Keast was born in 1945, in London, Ontario, where he proudly lived throughout his life. David grew up and was always proud to have been an “East Side Adelaide kid.” He attended Beck Secondary School before continuing his education at Western University, where he earned a master’s degree in chemistry. After completing Teachers’ College, David began his career teaching chemistry at Montcalm Secondary School, a role he held for 11 years. His passion for learning eventually led him in a new direction, and he was accepted to Queen’s University to study medicine, graduating in 1985. David went on to establish his own family practice, caring for patients for 25 years before shifting his focus to chronic wound management. He became a respected leader in the field and, for a time, served as Medical Director of the Outpatient Chronic Wound Management Clinic at Parkwood Institute in London. Throughout his career, David remained dedicated to education and advancing medical knowledge, teaching and publishing extensively while sharing his expertise with colleagues and future generations of healthcare professionals.

David was predeceased by his father Howard Keast, his mother Ruth Keast (nee O’Connor) and his beloved younger sister Deborah Lucy. He is lovingly survived by his wife, Heather (nee Ross); his son, Matthew and his children Jordan and Makenna; his daughter Erin and her daughter Maya; as well as his niece Kristin, her husband Ryan Ball and their children Ethan and Kyle. Also fondly remembered by his brother-in-law, Paul Ross, his wife Ruth Mercer Ross, her daughter Jennifer and her husband Mark McDougall, and their children Charles and William. He will be missed by numerous friends, colleagues and associates both at home and around the world.

Cremation has taken place. Family and friends are welcome for visitation on Thursday, August 27, 2026 from 2:00-4:00 pm and 6:00-8:00 pm at the A. Millard George Funeral Home, 60 Ridout Street South, London. A private family service will be held with future inurnment at Woodland Cemetery, London.

For those who wish to make a memorial donation in memory of David, the family asks you to consider the St. Joseph’s Healthcare Foundation, the Metropolitan United Church Foundation, or the Brain Tumour Foundation of Canada. The family would like to extend a warm thank you to the physicians, nurses, support staff and associates for the professionalism, kindness and compassion shown to David and to the family at LHSC. In closing, David would respectfully ask that we show a little more kindness and consideration to each other and to remember those who have not. This is how David lived his life.
