We understand that your schedule is valuable and can get busy, so we try to make it easy for you to reach us. We believe that you should always have access to your provider - whether it's in person, phone, text, or by email. Sometimes all you need is a quick question to be answered or you may be looking to book a comprehensive one-on-one session. Whatever the case, we're flexible and available - we'll make it work.


For a full comprehensive session, one-on-one appointments typically last 60-90 minutes depending on the services provided that session. New clients may require a 90 minute session for a full intake of history. 30 minute sessions are possible but are dependent on the severity and complexity of the condition being treated and not available for new clients. Two hour sessions are available upon request.

To learn more or make appointments, please contact Dr. Chang directly.
