Therapeutic Approaches and Online Care
Cletus uses a blend of structured, evidence-based methods to address stress, trauma, addiction, and relationship concerns. Cognitive Behavioral Therapy, or CBT, helps identify and change unhelpful thinking and behavior patterns to reduce symptoms and improve daily functioning. Acceptance and Commitment Therapy, or ACT, teaches skills to accept difficult feelings while clarifying personal values and taking committed action toward meaningful goals. Dialectical Behavior Therapy, or DBT, emphasizes practical skills for emotion regulation, distress tolerance, and interpersonal effectiveness, which can be especially helpful for clients dealing with intense emotional responses or relationship instability.
Choosing the right approach is a collaborative process. Licensed professionals like Cletus work with each person to assess needs, goals, and preferences, and they may combine elements from multiple therapies to create a tailored plan. This collaborative process focuses on finding methods that fit the individual and support real-world change.
Online therapy options include video calls, phone sessions, live chat, and text-based messaging, which offer flexibility for different schedules and comfort levels. These formats make it easier to maintain continuity of care across locations, accommodate work and family demands, and allow therapists and clients to connect in ways that suit the client’s life and therapeutic goals.
