Dr. Nick Flower

Licensed Clinical Psychologist/ OCD Spectrum President

Dr. Nick Flower is a Licensed Clinical Psychologist (Psy.D.) and the president of OCD Spectrum. He created OCD Spectrum to be the pre-eminent Obsessive Compulsive Disorder (OCD) and anxiety treatment center for Pittsburgh and the region. Dr. Flower graduated from Xavier University with his doctorate in clinical psychology in 2007 and has been licensed as a psychologist in Pennsylvania since 2010. He is a graduate of the Behavioral Therapy Training Institute put on by the International OCD Foundation (IOCDF) where he received specialized training in Exposure and Response Prevention Therapy (ERP). He is also the president of OCDPA, the Pennsylvania affiliate of the IOCDF. He is also a member of the Diversity Committee for the IOCDF where he works on ways to disseminate effective OCD treatment to under-served populations. For the past few years he has been a speaker at the annual IOCDF conference and has organized support groups for patients with harm OCD among other topics.

Dr. Flower has a warm and personal style with a sense of humor that allows for a good rapport with his patients. The type of therapy that he does is likely not what one might consider “typical” where the patient sits on a couch to discuss problems. It is an active and goal-directed approach so the patient can face fears directly while gaining a sense of mastery. His theoretical approach is largely based on something called Cognitive Behavioral Therapy (CBT). It’s an approach that focuses both on a person’s thinking patterns and behavior changes. In sessions, he will often help a patient examine thinking patterns and connect them with feelings so that they can change their behaviors. CBT has been widely supported in various research studies as an effective treatment approach for depression, anxiety, and many other disorders. He looks forward to working with you to help you conquer your OCD and anxiety.

Dr. Joshua Riley-Graham

Licensed Psychiatrist

Dr. Joshua Riley-Graham is a psychiatrist with a special interest in working with people struggling with OCD and anxiety disorders. He earned his undergraduate degree from the University of Cambridge before completing a PhD in Linguistics at the University of Maryland – College Park and an MD at the University of Kentucky. After medical school he completed residency training in General Psychiatry at Western Psychiatric Hospital/UPMC. He has experience working with people suffering from OCD, anxiety, body dysmorphia, depression, bipolar disorder, intense unusual perceptual experiences, and psychosis.

Dr. Riley-Graham takes a collaborative approach, helping people identify what is truly valued and important to them and assessing their experiences to determine what might be standing in the way of pursuing those values. Medications can be a helpful part of living a life worth living but not all problems need a medicine and no medication is right for every single person, no matter what their diagnosis might be. He works with people as a guide, someone who is knowledgeable about different options and approaches and will recommend a path but ultimately remembers that you are the one taking the journey.
