Executive Functioning Skills Coaches attend to their client’s unique academic, vocational, emotional, and interpersonal challenges related to difficulties with executive functioning. Coaches help their clients assess where they are now, identify where they want to be, and then determine how to reach their targets. This includes helping their clients with the practicalities of setting personal goals, building their motivation, maintaining their focus, and attaining their goals in a timely and organized manner.

Eight core executive functioning skills are targeted during coaching sessions.

Planning/Prioritization: Create roadmaps to reach your goals, Decide what to focus on, and what to let go of

Task Initiation: Begin projects without procrastinating, Increase efficiency

Time Management: Estimate your time and allocate it, Meet deadlines and hold limits

Organization of Workspace and Materials: Create and maintain systems to keep track of information and materials

Response Inhibition: Take time to evaluate the impact of behaviors and decisions, Think before you act

Working Memory: Follow multi-step directions and complete complex tasks

Sustained Attention: Attend to situations or tasks when they are tedious

Goal-Directed Persistence: Set goals and follow them through to completion

The goal of career counseling is to help you better understand yourself and the work world in order to make more informed decisions about education, career and life in general.

You could benefit from career counselling if you are:
* choosing a college or university major
* entering the workforce
* wanting greater satisfaction and meaning from your work
* considering a change of careers
* facing an unexpected change in your career path
* planning for a fulfilling retirement

Career counseling begins with an assessment of your current skills (e.g., education and training), interests (e.g., nature, business, helping, science), personality (e.g., sociable, logical, creative), values (e.g., work life balance, need for challenge), and preferred work environments (e.g., outdoors, fast-paced). This is attained through a combination of individual sessions with a career counsellor, a review of your academic/work experience, and questionnaires completed by you. A written report summarizing the findings is provided.

With this information in mind, you and your career counsellor will establish academic and professional goals and develop a strategy to reach those goals. The objective is to determine options that will lead to greater academic and/or work satisfaction while also meeting your lifestyle goals.

Work satisfaction has a significant impact on overall life satisfaction, particularly given that people spend a significant portion of their lives at work. Choosing academic and career options that match your interests and abilities will increase your happiness, self-confidence, and productivity, and at the same time prevent burnout, depression, and anxiety.

Dialectical Behavior Therapy skills groups (mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness) are offered for youth and adults. The skills groups are designed to provide alternative skills and strategies for individuals who tend to become overwhelmed by their emotions and engage in behaviors in response to these emotions that they would like to change. Skills can be helpful to reduce a wide range of behaviors, including aggressive behaviors, self-harm, substance abuse, binge eating, spending, gambling, social withdrawal, and procrastination. The group teaches four key sets of skills that enable participants to respond to intense emotions in more effective ways.

New Leaf Psychology Centre offers both an adult group and a youth/teen group. The teen group requires attendance of a parent. Parents attend the group with their child in order to support the application of new skills in the home. The format of the group is classroom style, with new skills being taught each session with opportunities to ask questions and practice. Tasks are assigned between sessions for additional practice.

** An intake assessment is necessary prior to attending the group. The intake assessment is done individually (one-to-one) for adults, and with the youth and at least one parent for the multifamily groups. These sessions are bookable online.
** The groups are being offered virtually only at present, and are not bookable online. Once you have completed the intake assessment our admin staff will enroll you in the group.
