About Peter
Peter Jastermsky is a Licensed Clinical Social Worker with 35 years of practice. He holds active LCSW licenses in California and Pennsylvania and has worked in settings ranging from employee assistance programs to outpatient mental health and substance use services. He uses a conversational, supportive style and meets adults where they are.
Sessions focus on clear goals and practical next steps rather than long explanations. He frames therapy as a partnership where the client is the expert on their life and the therapist offers guidance and perspective.
Background and approach
Peter has spent decades supervising and training other clinicians, so he brings experience from many clinical environments. That background informs a flexible approach to common problems like stress, anxiety, grief, depression, and life transitions. He also helps people facing workplace strain, caregiver stress, money worries, and issues tied to family of origin.
His methods include client-centered listening, cognitive behavioral techniques, mindfulness practices, solution-focused strategies, and existential conversation about meaning and choice. In sessions he helps clients weigh options, set realistic goals, and try small experiments to see what changes help. People who prefer straightforward, goal-oriented work tend to find his style useful.
He supports adults in thinking through decisions, managing emotions, and taking manageable actions to move forward.

Approaches That Work Online and In Conversation
Peter blends existential conversation with client-centered listening and practical cognitive behavioral tools. Existential work examines meaning, choice, and responsibility, which helps when someone faces life transitions, midlife questions, or a search for purpose. Client-centered methods focus on active listening and support so the client feels heard and understood as they consider options. Cognitive behavioral techniques look at thought patterns and behaviors and offer small experiments to reduce anxiety, manage mood, or change habits.Finding the best approach is part of the process. The therapist will collaborate with each person to decide which combination of methods fits their goals and preferences. Sessions may shift between exploring life meaning, practicing mindfulness skills, and trying behavior changes based on what is most helpful at the time.
Online formats include video calls, phone sessions, live chat, and text-based messaging to make therapy flexible. Video is useful for face-to-face conversation and deeper work, phone can be easier when bandwidth is low, and chat or messaging suits brief check-ins or people who prefer writing. These options let people fit therapy into work breaks, caregiving schedules, or different routines while keeping consistent progress with a licensed professional.
