About Peter
Peter Jastermsky is a Licensed Clinical Social Worker with decades of experience in counseling and supervision. He has worked across Employee Assistance Programs, outpatient mental health, and substance use settings. He brings a calm, conversational presence to sessions and focuses on practical steps people can take now.
He offers individual counseling for adults age 21 and up who live in California. His style is supportive and straightforward. Sessions begin where the client is and move at a pace that feels manageable.
Background and approach
Peter uses clear goals and simple, actionable choices in therapy. He helps clients weigh the pros and cons of changing habits, set meaningful goals, and take one realistic step forward. He believes people come to therapy to move beyond feeling stuck, not just to talk about why things happen.
His background includes clinical supervision and training other therapists. That experience informs how he organizes sessions and tracks progress with clients. He draws on techniques from client-centered work, cognitive behavioral strategies, and solution-focused planning.
Common concerns he addresses include stress, anxiety, grief, depression, life changes, career and workplace issues, addictions, relationship and intimacy-related questions, parenting challenges, anger, and self-esteem. He also helps with aging and caregiver stress, family of origin and communication problems, guilt and shame, loneliness, and questions about life purpose.
Sessions are offered in English and are available through video calls, phone, live chat, or text-based messaging. Costs vary by location and use a subscription model that can be canceled at any time.

Online support
Approaches that guide online sessions
Peter often draws on client-centered work, which focuses on listening closely to each person's concerns and helping them set their own goals. This approach helps when someone needs a supportive space to think things through and make decisions.He also uses Cognitive Behavioral Therapy, which looks at the link between thoughts, feelings, and actions. CBT offers practical tools for managing anxiety, depression, and stress by changing unhelpful thinking and testing small behavior changes.
Finding the right approach is part of the work together. He will collaborate with the client to choose methods that match their needs, goals, and preferences, and will adjust techniques as progress and feedback suggest.
Online therapy is offered through video calls, phone sessions, live chat, or text-based messaging to provide flexibility. Video is useful when visual cues help the conversation. Phone sessions can be easier when bandwidth is limited or a shorter check-in is needed. Live chat or text messaging work well for brief updates, working through immediate coping steps, or fitting therapy into a busy day.
These options make it easier to keep momentum and apply new skills between sessions while allowing the therapist and client to tailor the format to what works best.
