About Peter

Peter Jastermsky is a Licensed Clinical Social Worker (LCSW) with active licenses in California and Pennsylvania and 35 years of experience. He works with adults 21 and up on common life stresses such as anxiety, depression, grief, career concerns, addictions, relationship and family issues, and anger. He brings experience from Employee Assistance Programs, outpatient mental health, and substance use settings.

He uses a straightforward, conversational approach in sessions. He begins where a person is and helps weigh choices and consequences. He focuses on setting practical goals and supporting the steps someone wants to take. The work is often about moving forward rather than only examining why things happened.

Peter draws on Client-Centered methods to keep the session grounded in the person's goals. He also uses Cognitive Behavioral Therapy to spot unhelpful thoughts and develop different reactions. Mindfulness and Solution-Focused ideas show up when the task calls for stress reduction or short-term goal work.

Across his practice he emphasizes action that makes a measurable difference. He also brings experience as a clinical supervisor and trainer of other therapists. That background informs a practical, skills-oriented style rather than long, abstract discussion.

Sessions are intended for adults living in California and Pennsylvania. Sessions are conducted in English. Cost varies by location and sessions use a subscription that can be canceled at any time. To begin, a person is asked to complete a short matching questionnaire and schedule a first session via the online therapy options button.

How sessions work

How Peter blends approaches for online work

Peter commonly draws from Cognitive Behavioral Therapy and Client-Centered Therapy in his work. CBT focuses on identifying unhelpful thoughts and testing new behaviors to reduce distress, which can help with anger, anxiety, or workplace stress. Client-Centered Therapy centers the person's goals and experience, with the therapist guiding choices and supporting decisions rather than directing every step.

He also uses Solution-Focused ideas when the aim is short-term, practical change. Solution-Focused work narrows in on small, concrete steps that move a person toward measurable goals. Together these approaches support both understanding patterns and taking action to change them.

Finding the right mix of methods is collaborative. The therapist will work with the person to choose approaches that match their goals, preferences, and the problems they want to address. That conversation is part of the first sessions and may shift as goals evolve.

The biography does not specify exact session formats, so confirm current session options before booking. Online work can make it easier to fit sessions into a busy week, reduce travel time, and allow shorter check-ins when needed. Licensed professionals often use these benefits to help people manage anger, stress, and life transitions while keeping therapy aligned with daily responsibilities.
