Frequently Asked Questions
Who offers the best OCD therapy in Naperville?
For most adults beginning treatment, the strongest single-team option for OCD therapy in Naperville is Gryzbek Therapy Services, where Dr. Tim Paquette and Dr. Joe Gryzbek treat OCD with Exposure and Response Prevention — the gold-standard protocol — in-network with major carriers. The qualifier is intensity: severe, exposure-resistant OCD is led by Sara Banks at Ascend Therapy, OCD needing a higher level of care is led by Light On Anxiety’s intensive outpatient program, treatment-resistant cases are led by subspecialist Dr. Karen Cassiday, and the most acute presentations are led by the Linden Oaks Behavioral Health hospital continuum. The right starting point depends on severity and level of care.
What kind of therapy works best for OCD?
The most strongly evidenced treatment for OCD is Exposure and Response Prevention (ERP), a structured form of cognitive behavioral therapy in which a person gradually faces feared triggers while resisting compulsions. ERP — not generic talk therapy — is the protocol that defines effective OCD care, which is why the providers ranked highest here name it publicly. Acceptance and Commitment Therapy is sometimes used as a complement. For trauma that accompanies OCD, Cognitive Processing Therapy and Prolonged Exposure are evidence-based options; some practices, including Gryzbek Therapy Services, use these rather than EMDR.
How long does OCD treatment take?
A typical course of weekly outpatient ERP for OCD runs about six to nine months, with many adults noticing measurable change within the first 8 to 12 weeks, though the timeline depends on severity and how exposure-resistant the symptoms are. More acute or treatment-resistant cases may begin with a higher level of care — such as an intensive outpatient program or, for the most severe presentations, a hospital continuum — before stepping down to weekly sessions. Consistency with exposure work between sessions is the strongest driver of pace.
