About Philippa

Philippa Mariner is a licensed clinical social worker practicing in California with six years of professional experience. She focuses on helping people navigate stress, anxiety, depression, relationship concerns, self-esteem struggles, and life transitions, and lists ADHD among her areas of focus.

Background and approach

Philippa approaches clients with the assumption that each person knows their story best and brings strengths that can be built on in therapy. Her work also includes support for issues such as addiction, trauma and abuse, grief, intimacy-related challenges, and workplace or career pressures, along with a range of related concerns from communication problems to midlife questions.

Philippa emphasizes courage and collaboration, offering encouragement and practical guidance as clients take steps toward more fulfilling, balanced lives. She brings a compassionate, strengths-based perspective to sessions and supports clients as they explore goals and develop coping strategies tailored to their circumstances.

Evidence-based approaches and flexible online care



Philippa draws on evidence-based therapeutic techniques that emphasize practical skills and emotional insight. One common approach she uses focuses on building coping strategies for stress and anxiety through structured tools and behavioral techniques that help manage symptoms and increase daily functioning. Another approach centers on exploring patterns in relationships and self-esteem, helping clients identify unhelpful beliefs and experiment with new ways of relating that support healthier connections and greater self-compassion.

Choosing the right method is part of the collaborative process; she works with each person to identify which approaches align with their goals, preferences, and life circumstances. Together they review what feels useful and adapt the plan as progress unfolds, treating therapy as a tailored partnership rather than a one-size-fits-all prescription.

Online sessions are offered via video calls, phone, live chat, or text-based messaging to provide flexibility for different schedules and comfort levels. These options make it easier to fit regular work on emotional health into busy lives and to maintain continuity of care when in-person meetings are not practical. Licensed professionals can use these formats to deliver therapy that is accessible and adaptable to each client's needs.
