As well as addiction, Len is skilled in addressing challenging thought processes and negative beliefs that influenced their moods and behaviours. To further enhance his therapeutic approach, Len pursued training in Cognitive Behavioral Therapy (CBT) and Dialectical Behavioral Therapy (DBT) Skills, which he integrates into his therapeutic work.
Len enjoys working in one-on-one therapy, and he practises as a relational therapist. His passion extends to group therapy sessions, where he conducts psychoeducational groups on various topics, including self-esteem, emotional awareness, self-care, and financial well-being, as well as DBT skills training. He firmly believes in the power of these group dynamics to foster personal growth and positive change.

Why local healthcare in London matters

Medical practice in Reino Unido is governed by country-specific licensing, professional standards, and patient-safety regulations. Practitioners listed here are registered with the relevant Reino Unido medical authority and operate within national rules on scope of practice, prescribing rights, and continuing professional development. Care delivered in London carries the additional benefits of local language support, in-person follow-up, and direct coordination with regional hospitals and labs.
