The Children's and Adult Center was founded in 1998 by Dr. Tamar Chansky for children, teens and adults to meet the growing need for effective treatments for children and families contending with OCD and anxiety. We are a group of 5 private practice psychologists as well as a licensed clinical social worker with training and expertise in state of the art cognitive-behavior therapy for the full array of anxiety disorders, delivered in a warm, compassionate setting for children and teenagers, as well as for adults.


Our mission is to teach patients the skills they need to competently overcome the limitations that anxiety creates so that they can go on to lead happy, successful, and importantly, unburdened lives. Anxiety Disorders are among the most prevalent diagnoses in children and adults, but they are also among the most responsive to treatment. The prognosis is very good for those who are contending with an anxiety disorder, provided that they receive proper treatment.


Each of the therapists at the Center specializes in the treatment of anxiety disorders; our experience and additional specialties are described in our Therapist Profiles.


  •  Obsessive Compulsive Disorder
  •  Generalized Anxiety and Worry
  •  Separation Anxiety
  •  Panic Attacks
  •  Social Fears and Shyness
  •  Fears and Phobias
  •  Trichotillomania (Compulsive Hair Pulling)
  •  Medical and health related worries
  •  Tics
  •  Trauma
  •  Pediatric Autoimmune Neuropsychiatric Syndrome (PANS/PANDAS)

Frequently Asked Questions

How do I schedule an appointment?

If you are interested in setting up an appointment or getting more information, please contact one of the therapists at their phone number or email address listed in their therapist profile, or you can leave your information at our main mailbox (no extension) if you are unsure of how to proceed. Please note, if you leave a message in the main mailbox, you may experience a longer wait-time than if leaving a message directly with a therapist.

What days are therapists available?

The therapists all have different schedules and also have varying levels of availability given their current caseload. Most appointments are offered during the 9-5pm hours with some therapists offering evening hours. It would be best to read the bios carefully to determine which therapist(s) would be a good fit for your current needs. Contact the therapist directly at their extension and schedule directly. If the scheduling is difficult due to availability, the therapist will be able to help you proceed with other appropriate options.

How do I know which therapist is right for my child?

We recommend carefully reviewing the bios in the Therapist Profiles of all of the therapists and based on your current needs, selecting the best fit. Call the therapist and leave a message at the phone number listed on their bio. They will speak with you to discuss your needs and determine if they are the right fit. They will also be able to help you proceed if they feel another option would be more appropriate.

Do any therapists accept insurance?

None of the therapists accept insurance or are currently on any insurance panels. Dr. Chansky, Dr. Siqueland, Dr. Ledley, Dr. Baxt, Dr. Khanna's practices are all fee-for-service practices. However, all therapists provide receipts that can be submitted for reimbursement if you have out of network benefits.

Those not local to the Philadelphia/Western Suburbs area, you may contact your nearest university hospital for an appointment or for recommended providers or visit our partner website at www.CopingCatParents.com for a "Global Network" list of providers in CBT for anxiety and other helpful referral resources and tips on finding an evidence-based treatment provider. ​

The most complicated part of finding us is identifying our Center from the street from the first time because it is a residential building of white stucco with brown shutters (see the photo above). There is a post and rail fence out front and a small wooden sign with our address 3138 Butler Pike. There is no sign saying Children’s Center from street or identifying it as a business location. After locating us the first time, it will be easy. Go slow once you turn onto Butler Pike. Park anywhere there is a free space in the large lot.

Go in the door marked Children’s Center for OCD and Anxiety and go up the stairs. At the top of the stairs, go thru the right side door to this 2nd floor waiting room. Take a seat in the waiting room. Your therapist will greet you there.
