About Peter

Peter Jastermsky is a Licensed Clinical Social Worker with 35 years of experience. He works with adults and brings a calm, conversational style to sessions. He has helped people in settings that include employee assistance programs, outpatient mental health, and drug and alcohol services. Peter has also supervised and trained other therapists, which informs his practical approach to counseling.

He starts therapy by meeting each person where they are. Sessions focus on clear choices and doable steps rather than only exploring past reasons. Peter helps people weigh the consequences of changing or staying the same, set meaningful goals, and move toward those goals. He emphasizes that the client is the expert on their life and will support their decisions.

Many people come for help with stress, anxiety, depression, grief, anger, addictions, and life changes. He also addresses work and career concerns, relationship and intimacy issues, parenting stress, caregiver burden, and feelings of isolation. His background includes work across diverse service settings, so he is familiar with practical problems people face every day.

Peter uses several straightforward therapy methods to guide sessions. He leans on client-centered conversation to build understanding, cognitive-behavioral tools to address unhelpful thoughts and habits, and mindfulness to help manage stress. He also uses solution-focused steps to create quick, measurable progress.

Adults 21 and up who live in California and Pennsylvania are the focus for his individual counseling. Sessions use a subscription that can be canceled at any time. To begin, choose the Start Therapy button, complete the short matching questionnaire, and schedule based on therapist availability.

Therapeutic approaches and how they fit into online care

Peter uses client-centered therapy to create a respectful, listening-based space where the person's own goals guide the work. This approach helps when someone needs careful listening and support to make decisions about life changes.

He also uses cognitive behavioral therapy, which focuses on identifying unhelpful thoughts and habits and changing them with practical exercises. CBT can be useful for anxiety, depression, anger, and stress when people want tools to change how they think and act.

Finding the right approach is part of the work together. Peter will talk with each person about their needs, goals, and preferences, and then suggest which methods to try. The process is collaborative and can be adjusted over time as goals change.

The biography does not list specific session formats, so confirm available online options before booking. In general, online work can make it easier to fit sessions into a busy life, reduce travel time, and allow shorter check-ins when schedules are tight. Many people find that talking from their usual surroundings helps them practice new skills in daily life, and that structured exercises like CBT tasks translate well to remote sessions with a licensed professional.
