Karen Cassiday, Ph.D., A.C.T.


Philosophy of Care: 

Dr. Cassiday empowers patients to overcome their struggles with anxiety, compulsions, phobias, social anxiety, worry, and depression. She approaches each patient with enthusiasm, persistence, and a keen sense of humor, crafting individualized, research-based treatment plans for each person.  Her goal is to make each patient an expert at managing their own anxiety, so that they can face any future event with confidence and courage. She loves being able to laugh and celebrate along with patients as they overcome their most difficult situations.

Special Interests: 

Dr. Cassiday is often sought out to treat the most challenging patients who have not had success in other adaa-clinical-fellowtreatment environments.  She is particularly skilled at working with complicated cases of anxiety disorders, young children, selective mutism, OCD and school refusal.  She also specializes in working with parents.  Her experience as a special needs parent gives her a unique insider’s perspective, and she understands the challenges of balancing work, family, and a child’s complex needs.

Dr. Cassiday is the mother of two boys who she credits with helping her fine tune her sense of humor.  She spends her free time hanging out with her kids, dog and husband in the outdoors, cooking for a crowd, reading, exercising, and eating chocolate!
