About ISM

ISM were founded in 2014 to provide interventions and training throughout Scotland. We work with individuals, community groups, local authorities and private care companies.

The services we provide are:

ISM Psychology

Sharron Reilly - Director

Sharron has worked for more than 25 years in justice, health, social care and education. She set up ISM Psychological Services in 2014. She developed the Drink Drive Rehabilitation Scheme (DDRS) Course which was approved by the Secretary of State in 2015. Sharron has used her doctoral research on drink driving interventions to develop the 50k Pint, a short preventative drink and drug driving course aimed at keeping roads safer and reducing convictions. Sharron is passionate in her work with young children and families, and her therapeutic stance allows her to engage with young people easily. She has a specialist interest in attachment and trauma difficulties. This easily positions her to work with professionals in residential childcare where she has developed a Therapeutic Parenting in Residential Child Care (TPRCC) intervention which is being put through SQA for quality assurance. Sharron has a BA (Hons) in Social Science and Psychology, an MSc in Forensic Psychology and an MSc in Applied Psychology with Children and Young People. She is a qualified and registered Clinical associate in applied psychology and is an Applied member of the British Psychological Society (BPS) and is currently being supervised by Dr Dawn Harris.

Martin Reilly – Director

Martin has successfully facilitated more than 350 Drink Drive Rehabilitation Scheme (DDRS) courses. He started at ISM in 2014 was promoted to lead facilitator in 2018. While he continues to facilitate DDRS courses, he also offers support and supervision to new facilitators. He has firsthand experience of the criminal justice system, and we believe that his own rehabilitative journey allows him the unique position to empathize and build a rapport with all clients. He has been involved in the development of the DDRS since its inception and has been crucial for building client contact and engagement. Martin has also worked with Sharron in developing the innovative Preventative Drink and Drug Driver course. Martin leads on the “train the trainer” course for this intervention allowing him to spread the word, making roads a safer place and further reducing convictions.

Tracey Trousdale – Office Manager

Tracey joined the ISM team back in 2016 with a goal of introducing consistent and sustainable administrative practices. Her role quickly evolved with the growth of the business, and she developed an effective and efficient operating process. Tracey is meticulously organised which gained her a promotion into the role of the office manager in 2018. Tracey is now responsible for all corporate reporting, scheduling and coordination, not content with this already busy role, Tracey also trained in facilitating the DDRS courses proving her status of a woman with many talents.

Shannon Gallagher Murdoch – Assistant Psychologist

Shannon is an Assistant Psychologist with a BSc (Hons) in Psychology and almost 7 years of experience working with ISM Psychological Services starting here in 2019. For the past five years, I’ve specialised in facilitating Drink Drive Rehabilitation Courses, supporting individuals to understand their behaviour, make positive changes, and reduce reoffending.

Shannon is passionate about helping people build self-awareness and resilience through psychological insight and reflective practice. Her approach is grounded in empathy, evidence-based techniques, and a genuine belief in people’s capacity for change.

Shannon is gaining experience working with children and young people, supporting them to understand their emotions, behaviours, and experiences through age-appropriate psychoeducation. She aims to create a safe and supportive space where young people can explore their feelings, build coping skills, and develop a better understanding of themselves. Her approach focuses on helping children make sense of difficult experiences in a way that feels manageable and empowering. Shannon believes that helping young people understand why they feel the way they do can be a powerful step toward building resilience and emotional wellbeing.

Donna McAllister – Facilitator

Donna joined ISM Psychological Services in 2023 to support the growing demand for our DDRS courses. Training alongside Shannon and Martin, she quickly became an integral part of the team and now facilitates courses from our Bathgate office.

With over 20 years of experience in the motor industry, Donna works full-time as an Accounts Assistant and serves as her company’s Health and Safety Officer. Her role extends beyond numbers — she is involved in staff development, delivering training to apprentices, graduates, and experienced colleagues alike.

Donna brings professionalism, warmth, and a wealth of real-world experience to every course she delivers, helping participants feel supported, understood, and motivated to make positive changes. She really is amazing at what she does.
