About John
He begins by listening to each person’s story and identifying strengths they already have. Sessions are pragmatic and direct. He encourages small, doable steps and practical strategies that fit into everyday life. Conversations focus on what is causing distress now and what can be tried to make things more manageable.
Over nearly three decades he has worked across settings and with a range of mood and personality concerns. That experience informs how he helps people handle co-occurring problems like communication difficulties or feelings of guilt and shame. He also brings experience supporting people through divorce, blended family issues, and end-of-life topics.
Dr. Mansdorfer aims to collaborate with clients to set clear goals and to monitor progress. He treats life purpose as a practical concern - questions about meaning and direction that can be discussed, tested, and adjusted over time. His approach is straightforward and focused on helping people move forward in small steps.
Sessions are conducted in English and reflect a long career working with mood disorders, stress responses, and life transition challenges. Before booking, readers should confirm current session options and formats.

How therapeutic approaches translate to online sessions
Evidence-based techniques form the backbone of his work. One common approach is structured problem-solving, which breaks larger issues into small, testable steps and helps with anxiety, depression, and feeling stuck. Another is mood-focused work that tracks symptoms, identifies patterns, and supports clearer daily routines to stabilize mood swings and manage bipolar or depressive symptoms.Choosing an approach is collaborative. He will discuss what has or hasn’t worked for you and adapt methods over time. Together you set goals, try strategies, and check progress so the plan changes as needed based on your experience and preferences.
