Alex Munter is President and Chief Executive Officer at CHEO, bringing to the role more than 25 years of leadership in health and social services and an incredible commitment to helping children, youth and families in our community and beyond.

CHEO is one of Canada’s few stand-alone, full-service tertiary pediatric health and research centres, serving the national capital region, eastern and northern Ontario, western Quebec and Nunavut. Since joining CHEO in 2011, Alex has helped the organization evolve from a 20th Century hospital to a 21st Century integrated child and youth health system to better deliver on its vision of the best life for every child and youth. 

Over the past nine years, CHEO has become a digital heath leader, among the top 1% of Canadian hospitals. The organization has cut wait times, increased safety and improved efficiency through pioneering use of Lean methodologies in a pediatric setting. CHEO has twice been named best place to work in Canadian health care by Forbes, twice named one of Canada’s most admired corporate cultures by Waterstone Human Capital and ranked one of the world’s best children’s hospitals by Newsweek. It’s also been rated a best Ontario hospital in which to practice by physician engagement surveys, earned highest ratings for patient satisfaction and has been named one of Ottawa’s top employers nine times. Through its work pioneering the Kids Come First Health Team in eastern Ontario and the Kids Health Alliance in Ontario, CHEO has played a leadership role beyond its walls to create a better-connected health system that benefits children and families alike.

During his tenure, CHEO has also seen significant growth in patient and family engagement in research, improved integration of research into clinical care and grown its leadership in research in molecular biomedicine, health information technologies and at the bed side.

A respected leader in the Canadian health-care system, Alex sits on the boards of the Ontario Hospital Association, Children’s Mental Health Ontario, Kids Health Alliance and the Health Insurance Reciprocal of Canada (HIROC). He has been appointed to a wide variety of government advisory committees on topics ranging from health-system funding reform, health-care worker influenza immunization, health-information systems renewal, childhood obesity, public health-system capacity, immune globulin therapy funding and system efficiency and alignment. During the 1990’s, he was very involved in the restructuring of hospital and other health services in the Ottawa area as a member of the District Health Council.

Prior to joining CHEO, Alex was Chief Executive Officer of the Champlain Local Health Integration Network (LHIN) — the provincial government agency responsible for planning, integrating and funding health services in the region. He strengthened the region’s health system by making strategic investments at hospitals and community-based agencies in both urban and rural areas in the region. In particular, he made great strides in improving care for the elderly by putting in place programs that help vulnerable seniors stay independent and healthy in their own homes for as long as possible. Prior to joining the LHIN, Alex was Executive Director of the Youth Services Bureau (YSB), one of Ontario’s largest accredited children's mental health agencies. During his tenure, the organization grew by one-third, adding services and expanding its reach. It won recognition for a ground-breaking new health clinic for street-involved youth, the establishment of a youth mental health hub and launch of innovative new clinical mental health programs, closer co-ordination between hospitals and community mental health providers, new programs to help at-risk youth find and keep jobs and new measures to improve the agency’s governance, efficiency and service quality.

Alex was a City and Regional Councillor in Ottawa from 1991 to 2003. From 1997 onward, he headed council committees responsible for health and social services with oversight of the city’s $550 million human services budget. In that role, he led Council to unanimously adopt pioneering smoke-free regulations in 2001; helped open new child-care centres, expand the number of child-care spaces, and expand public health programs for children and youth; worked with provincial government to oversee the transfer of ambulance services and social housing to the municipal level; initiated Canada's first comprehensive public access defibrillator program; expanded long-term care for seniors; funded hospital expansions and worked with the Community Care Access Centre and community support agencies to improve at-home support services for seniors and people with disabilities.

Alex holds a Bachelor of Social Sciences (BSocSc) degree from the University of Ottawa, a Master of Science (MSc) degree in Behavioural Science from the London School of Economics and a professional designation as a Certified Health Executive (CHE) from the Canadian College of Health Leaders. After leaving city government, he was a Visiting Professor in the School of Political Studies at the University of Ottawa, teaching there and at Montreal’s Concordia University.

Alex has brought his leadership to a wide variety of community organizations, previously co-chairing the National Network on Ethnocultural Communities and AIDS, chairing the Ottawa Local Immigration Partnership, sitting on the Ontario Advisory Council on Multiculturalism and being a member of the boards of the Community Foundation of Ottawa, Ottawa Art Gallery and Ottawa-Carleton Children’s Aid Society.

Alex has won numerous awards from a wide range of organizations for his contributions to the community, including the Centre for Addiction and Mental Health, the Canadian Institute for Child Health, United Way/Centraide Ottawa, the Federal Business Development Bank, l’Association Canadienne-Française de l’Ontario d’Ottawa, Leadership Ottawa and the Ontario Association of Social Workers. In the 1990s Alex was awarded the Ontario Volunteer Service Award. Most recently, in 2012, he was awarded the Ontario Francophonie Award and the Queen's Diamond Jubilee Medal. In 2019, he received the Outstanding Alumni Award from the University of Ottawa Faculty Of Social Sciences.

Mari Teitelbaum

Vice President of Strategy, Quality and Family Partnership and Chief Innovation Officer

Mari started her career as an electrical engineer, where she recognized the value of technology to enable efficiency and effectiveness. After ten years in the high tech industry, she decided to go back to school and get her Masters of Health Administration at the University of Ottawa. As the daughter of a CHEO physician and a mother herself, she passionately believed that she could use her technology skills to help clinicians care for kids in this community.

Mari completed her MHA residency in CHEO’s Information Services/Information Technology department, building a five-year strategy for the hospital which included the path to an electronic health record. She then joined the team at BORN (Better Outcomes Registry & Network) as Manager of Health Informatics. Her skills and enthusiasm were quickly recognized, promoting her into the leadership team responsible for the delivering on the promise of BORN.

Mari spent five years as the Director of BORN Ontario, solidifying the organization and building a large and complex electronic database – learning all about how clinicians use technology and, more importantly, how they can use the information it provides to improve clinical care.

Joanne Lowe

Vice president Mental Health and Addictions

Joanne Lowe was a leader at CHEO’s mental health program until 2011 and is currently Executive Director of the Youth Services Bureau (YSB). She will continue in that role but now wears a new hat as well, as CHEO’s new Vice President of Mental Health and Addictions — a first of its kind role across Canadian pediatric hospitals.

She is responsible for all of our clinical mental health programs and the Ontario Centre of Excellence for Child and Youth Mental Health and splits her time between YSB and CHEO evenly. The greatest increase in demand for our services over the past decade has come from young people in mental health crisis. It’s clear that this challenge can’t be solved within the walls of CHEO alone. Joanne’s appointment to this shared role between CHEO and YSB is intended to advance our common goals of preventing children and youth coming into the Emergency Department if they can be helped elsewhere, improving capacity to respond to the needs of those who are high-risk, improving pathways for follow-up and improving transitions across age span from childhood to adulthood
