Jonathan Mitchell

Programme Director, Counsellor and DBT skills trainer

Glenbrook Practice was established by Jonathan in 2025 following his three-year full time tenure at a clinic where he honed his expertise in family therapy, group therapy, and dialectical behaviour therapy (DBT). Jonathan also played an instrumental role in managing and running the DBT group. During this time, he realised the importance of DBT skills and recognised their value as crucial life skills in helping people.

After this incredible experience, he then went on to attain a BA degree in HEALTH SCIENCES and SOCIAL SERVICES in psychological counselling. Jonathan also attended Lifeline courses, a personal growth course, and a counselling skills course at Lifeline and had the privilege to volunteer for Lifeline for one year.

Glenbrook Practice’s core focus lies in providing DBT skills training for adolescents, adults, and individuals diagnosed with Borderline Personality Disorder. Additionally, Jonathan co-facilitates the Parent Support Group, the BPD support group, and three DBT outpatient skills programs.

The philosophy of Glenbrook Practice revolves around the principle of “Growth through awareness.” This principle underscores the significance of self-awareness and insight in fostering personal growth and development. Specifically, within the context of Glenbrook’s practice and clientele, this philosophy embraces the belief that individuals can achieve positive changes and progress by gaining a deeper understanding of themselves, their emotions, thoughts, and behaviours through acquiring new skills. Essentially, the practice’s philosophy reflects a commitment to empowering individuals with the tools and knowledge necessary for self-improvement and growth.

Laeni Gittins

DBT Facilitator – Tweens & Teens 

Laeni has always had a passion for children and their well being. A strong believer in open communication, when dealing with both adults and children, she believes when the basics are impaired, it usually leads to misinterpretation and misunderstanding.

Laeni regards The Step-Upp® Tweens programme as instrumental in equipping children with essential tools to deal with conflict and change, early in life so they grow up to be resilient, happy and successful adults.

Being a mother herself, Laeni understands the importance of skills-based training for children; particularly when faced with the ever changing environment in which they are growing up, such as new technology and social media.

She is confident that the skills children gain through the programme will be invaluable to successfully navigating life’s challenges.
