Rancho Cucamonga Office


Online Scheduling for the Rancho Cucamonga office is currently available only for IEHP Autism Evaluations. We are working to add additional services available for online scheduling. In the meantime, please feel free to email our office (info@gunnpsych.com) or complete the Insurance Survey if you are interested in scheduling an appointment with us.

Also, online scheduling is available only for first time appointments. If you have received services with us previously, please contact your therapist/psychologist directly or call our office to make an appointment. Provider email addresses are available here:

If you are an IEHP member needing to schedule an autism evaluation and looking for an appointment more quickly, we may have such appointments available through traditional scheduling. Please email (info@gunnpsych.com) or call our office to check on availability.
