Dr. Deal completed her second term as Chief of Endocrinology and Diabetes at Ste-Justine Hospital in 2020 and became a full professor at Sainte-Justine Mother-Child Hospital, where she had served since 1992. She became professor emeritus in 2021 and is still very active in local, national and international teaching in the field of pediatric endocrinology. She has been a member of ELNA Pediatrics Tiny Tots since August 2021.

Dr. Deal co-edited the first comprehensive textbook on maternal-fetal and neonatal endocrinology and has published over 150 articles and 200 abstracts, in addition to presenting 180 lectures nationally and internationally. Dr. Deal is also President-Elect of the Canadian Society of Endocrinology and Metabolism, Council Member of the Growth Hormone Research Society, Training Director for the Royal College Program in Pediatric Endocrinology and Diabetes at Université de Montréal, Site Director for the Pan-Canadian Child Health Clinical Scientist Training Program, and Council Member of the International Society of Endocrinology.

Dr. Deal’s research interests focus on growth and the growth hormone axis. She has also contributed to the explanation of molecular defects associated with a variety of rare pediatric endocrine disorders and has been involved in clinical trials and the development of clinical practice guidelines aimed at improving outcomes in endocrine disorders such as short stature, early puberty, congenital hypothyroidism, congenital hypopituitarism/GH deficiency, autoimmune polyglandular syndrome, Prader-Willi syndrome, and Turner syndrome/SHOX deficiency.

She is not only involved in clinical practice, but also in research and teaching enabling her to be more proficient in her field. Her priority has always been the well-being of the patients and families she cares for, and nothing gives her more satisfaction than seeing her patients go home with a smile!
