Parenting challenges led him to the work of clinical psychologist, Marshall Rosenberg. Rosenberg’s Nonviolent Communication (NVC) training has enabled a transformation in his personal and professional relationships and he incorporates this approach in his therapy work and coaching.. Glenn shares this work in workshops and groups. He is one of the founders of the International NVC Caravan which promotes the advancement of Nonviolent Communication in organisational and institutional life.

Approach: Glenn is a passionate believer in the role that personal and professional development can play in helping people live a more fulfilling life and deal with difficult situations that may arise throughout. He provides a safe, supportive and non-judgemental space for his clients to speak honestly and openly. He supports them to navigate and understand their difficulties while encouraging and supporting them to consider different choices. He works in a relational way, meaning that he believes the relationship with the client is key to the success of the therapy.

He is very interested in the role that communication plays in our lives, both our communication with others and our internal dialogue. He supports couples and groups to explore their communication patterns, helping them find alternative ways of expression so that they can feel heard.

He has cited the challenges associated with being a manager of people as being pivotal to engaging in management training. He trained extensively with Sandy Cotter in Development Psychology and Organisational Politics at Cranfield University in the UK. He later completed a five-year training in body-oriented psychotherapy (Biosynthesis) in Switzerland with the late David Boadella.

Glenn is also a Swim Ireland and Shaw method accredited swimming teacher and specialises in helping fearful and nervous swimmers address their relationship with water. He speaks French and is learning Portuguese and Arabic. He relaxes by waterskiing on the Shannon.
