Need help? Let’s get clarity

Clarity California provides psychological testing for diagnostic clarification and treatment planning assistance for children and adults in the Southern California area.


“Therapy without testing is like surgery without an x-ray. "

Clarity California was founded by Dr. Colleen Long, who believes that therapy shouldn’t have to last a lifetime. By implementing testing - we are able to rule out or confirm suspected diagnoses quickly as well as assist in the most laser focused treatment targets. This allows both you and your health care provider to ensure that you are always on track and making progress.

Please note- We provide autism screening and testing, but do not administer the ADOS-2, which is required by some programs and insurance to qualify for an ASD diagnosis in their view. We provide autism diagnoses based on the research and DSM V- TR standards, which does not align with those views and opinions often found on social media. If you are seeking autism because of something you read on tiktok: A list of providers who can help you, can be found HERE.
