About Dennis
He uses practical tools and simple conversation to address problems. That often means working on communication skills, coping strategies, and clearer decision making. He pays attention to how past hurts affect present choices and helps people find ways to move forward.
Dennis has particular sensitivity to mens issues and the struggles young adults often face. He also works with people coping with trauma, grief, career stress, ADHD, and compassion fatigue. He helps people who want to improve self-esteem, intimacy, and day-to-day functioning.
Therapy with him blends listening and direct work. He draws on approaches such as client-centered methods, cognitive behavioral ideas, dialectical behavior strategies, and emotionally-focused practices. Sessions aim to be collaborative, with goals set together and adjusted over time.
People who want clear, practical steps and a therapist who will challenge and support them may find his style helpful. Before booking, readers should confirm current session options and any scheduling details that matter to them.

How therapeutic approaches translate to online work
Client-Centered Therapy focuses on listening and building understanding. It helps people feel heard and supports self-directed change by following the client's priorities. Cognitive Behavioral Therapy, or CBT, looks at how thoughts and behaviors maintain problems and offers practical exercises to change patterns that feed anxiety, depression, anger, or sleep and eating problems. Dialectical Behavior Therapy, DBT, teaches emotion regulation, distress tolerance, and interpersonal effectiveness skills that are useful for strong emotions and relationship challenges.Finding the right approach is part of the work. The therapist will talk with each person about what feels most helpful and will try approaches that match their needs and goals. Decisions about technique are collaborative and adjusted as progress is made.
The therapist's biography does not list specific online session formats. Confirm which session types are offered before booking. Many people find remote options useful because they make it easier to fit appointments around work, reduce travel time, or choose a shorter check-in when that suits the day. Online sessions can let someone keep continuity of care during life changes while working on communication, coping skills, and managing anger or other symptoms.
