A narrow practice, on purpose.

Ashfield Center was set up to do one category of work properly rather than a wide range of it adequately. Everything below follows from that decision.

How we work

A consulting room with two armchairs beside a window

Treatment starts with an assessment rather than a first session. We want to know what the anxiety attaches to, what has already been tried, and what has quietly been arranged around it — the routes not driven, the situations declined, the reassurance asked for. That picture is what the plan is built from.

From there the work is active. Exposure-based treatment asks something of you between appointments, and we are straightforward about that at the start rather than introducing it in week five. What you get in return is a method with decades of evidence behind it and a clear way of telling whether it is working.

We review progress openly every six to eight weeks. If the plan is not moving, it changes — and occasionally that means referring you to someone whose training fits better than ours. That is a normal outcome here, not a failure.

Meet the
co-directors

Dr. Helen Marchetti, PhD

Clinical Psychologist · Co-director

Dr. Marchetti treats obsessive-compulsive disorder with exposure and response prevention, alongside panic, generalized anxiety and specific phobias. She is particularly interested in the cases that have already been through treatment once and did not hold.

Adjunct faculty, Placeholder State University
Works with adolescents and adults

Dr. Iris Kwon, PhD

Clinical Psychologist · Co-director

Dr. Kwon works across OCD, health anxiety, trauma and insomnia, with an emphasis on getting to a workable plan quickly. She is direct about what the evidence supports and what it does not, which most clients report finding a relief rather than a shock.

The space

A quiet suite on the second floor with parking directly outside, which matters more than it sounds when part of what you are treating is the dread of the appointment itself.
