Mark has accepted the role of President and CEO of Oak Valley Health in Markham, Ontario, a tremendous opportunity that reflects his strong leadership and contributions to healthcare.
While we will miss Mark’s presence and leadership, his departure does not take away from the important momentum we have toward our integration with Grand River Hospital. We also want to celebrate Mark’s accomplishments at St. Mary’s and the lasting impact he has made on the Hospital and the broader communities it serves. During his tenure, Mark’s focus on high quality patient-centered care, innovation, strategic leadership, and community partnerships that have positioned St. Mary’s as a leading healthcare institution, ready to meet the evolving needs of the community.
As member of the St. Joseph’s Health System (SJHS), SJHS will appoint an interim President to guide St. Mary’s from late January 2025 until the planned integration with Grand River Hospital in April 2025. Mark will work closely with the Hospital’s leadership team to ensure a seamless handover of responsibilities, leaving St. Mary’s well-prepared to continue delivering exceptional care and advancing our integration and redevelopment work.
While Mark’s departure marks the end of a significant chapter for St. Mary’s, it also represents an exciting new beginning for him and Oak Valley Health. We are deeply grateful for Mark’s contributions, which have set a strong foundation for acute care in Waterloo-Wellington, and beyond. His strategic vision, collaborative spirit, and dedication to improving healthcare will undoubtedly serve him well in his new role.
Please join us in congratulating Mark on this next chapter in his career.
Sincerely,
Elizabeth Buller
President and CEO
