It offers a safe environment for the individuals to share and process their experiences as well as develop insights into what is underlying their current challenges. Psychotherapy also provides individuals with coping strategies and skills to tackle life’s daily challenges. My role as a clinical psychologist is to provide you with this safe and therapeutic relationship, guide you through your exploration and path to growth, as well as offer you the opportunity to learn new skills and improve your functioning in order to enhance your life-journey.” Dr. Ibrahim
