Dr. Tonya Crombie has over 25 years’ experience in executive coaching and maximizing leader and employee performance. Tonya began her career as an organizational and leadership development consultant in a large international consulting firm. After providing executive coaching and leadership and organizational development consulting to clients such as IBM, Pepsico, and various Fortune 100 organizations, Tonya accepted an opportunity to work within the HR department at Intercontinental Hotels Group.  At IHG, she progressed to leadership roles in HR, where she led the teams responsible for employee and organizational development, recruitment and retention, management/leadership development including the development of high-potential employees and succession plans for the global organization.

Tonya left IHG in order to spend more time with her young growing family and also to focus on one of her first loves, teaching.  Tonya authored several courses for distance MBA and Organizational Research degree programs, while devoting the majority of her time to being at home with her two young children.  In 2012, Tonya founded Guidance for the Future, a strengths-based coaching practice.  Through her work with Guidance for the Future, Tonya was also offered a high school teaching position where she instructed juniors and seniors in areas such as: identifying strengths, factors that increase life satisfaction, and using strengths in leadership roles.

Tonya is also the bestselling author of Stop Worrying About Your Anxious Child and the upcoming Stop Worrying About Your Anxious Teenager.  In addition to teaching parents the best techniques to help their children when they struggle with stress, overwhelm, and anxiety, Dr. Crombie also works with managers, leaders, teachers and school staff to better understand, identify, and manage anxiety in the workplace and the classroom.  This work is crucial to success as anxiety is the most common mental health issue among adults and children.

Tonya has a Ph.D. in Industrial and Organizational Psychology and an MBA.  She is a highly skilled executive coach and is a requested facilitator and speaker on the topics such as anxiety identification and management, leadership and talent development- particularly in the area of identification and management of strengths, and navigating the way forward when it isn’t clear.
