1215 Hall Johnson, Suite 100
Colleyville, TX 76034 Map It!

My office is located in Colleyville (about 10 minutes West of DFW Airport) on the southwest corner of Colleyville Boulevard (Highway 26) and Hall Johnson, behind Metzger Dentistry. One of the easiest ways to get to my office is exiting Hall Johnson Road from Highway 121. Head west onto Hall Johnson road from 121 and travel approximately 4 miles. At the intersection of Highway 26 (Colleyville Boulevard), Bluebonnet Cemetery is on the right corner, and McAlister’s Deli to the left. Cross through the intersection and take the first left (addresses 1213-1215). Our offices are located in the back of the parking lot – there is a white sign “Psychology Offices” pointing to the right.
