About us


Livingston Psychological Services is committed to providing wholesome remission to our clients.

B ecause we care, we are committed to serving each client with the same quality as we would family and friends. No one is more passionate about the dedication and efforts put into our services than our providers and staff. It comes from knowing our specialties and the qualities we implement into each of our unique specialty that matters.

It comes from the knowledge of the that first phone call answered with compassion on the other end of the phone, the moment you walk into our office and are greeted with kindness and smiles but real empathy. It comes from our providers many years of experience in doing what all it is they do, and from that experience comes years of knowledge in how to assess each situation to the best treatment plan we can implement.

Those barriers frequently are characterized by poor social skills, emotional disorders, inability to cope with adversity and frustration, inadequate life planning, self-destructive behaviors and poor judgment when making decisions.
