Brief Therapy

Practicing Brief Therapy means seeking to help clients solve their problems in the most rapid, complete and sustainable way possible.

At an initial consultation, we explore the clients' current issues, establish the focus of therapy and start looking for practical ways to promote change.

Depending on the desire of the client and the nature of the problem, others who can be involved in the solutions might be asked to participate.

Frequently, "homework" is suggested in-between sessions, so that change is actively being pursued both inside and outside the therapy office. This helps to dramatically shorten the therapeutic process and therefore reduce the therapy duration.

The therapy ends after a consolidation phase, which enables the client to ensure that the desired change is sustained.
