Make an appointment with Dr. Williamson
To make an appointment with Dr. Williamson, print and complete the Patient Information Form paying particular attention to the “Concerns” section on page 3. Failure to complete sections of this form may result in a delay in scheduling. Copies of previous testing including standardized tests administered by schools or private facilities should accompany the Patient Information Form. The information in the Patient Information Form and previous testing determines what type of evaluation should be scheduled and what additional forms are necessary. Mail this information along with an application fee of $50 to the address on the form. (This non-refundable application fee is deducted from the charge for your first appointment and is not an additional charge.) FORMS MUST BE MAILED WITH YOUR CHECK. WE DO NOT ACCEPT FAXED FORMS or CREDIT CARDS BY TELEPHONE.

If the patient is being referred from Kelsey-Seybold and is in an HMO, you must have a formal referral and an application fee is not required. To make an appointment, you must send a copy of the referral letter from K-S Utilization Management along with the Patient Information Form as well as copies of previous testing including standardized tests administered by schools or private facilities.

If you have not heard from our office within a week of mailing your forms, please call our office (713-500-8300, option 7), as this will likely mean your forms did not reach us. (We highly recommend keeping copies of everything you provide to us.)

Once appointments have been scheduled, we will send a written confirmation with additional forms for completion by parents and teachers (if applicable). Our confirmation letter will also provide a date by which all forms must be received in our office to prevent the necessity of canceling the appointments. Dr. Williamson must receive the completed forms prior to the appointment.

When returning this second set of forms, please include copies of recent report cards and previous medical history if related to the present evaluation. This history usually includes reports from neurologists, psychologists, and/or therapists and MRI’s, CT scans, hearing tests, chromosome studies or any significant medical history. Please send copies and not your originals.
