I am not in my offices everyday but do my best to check voicemails at least once a day. Please feel free to get in touch with me via phone or text.  If you are experiencing a crisis, I encourage you to utilize the crisis services available to you in your county. 

My office is conveniently located in downtown Walnut Creek. My Walnut Creek office has parking in the back of the building. Please pull in to the driveway on the left side of the building. You may enter the office either through the parking lot or in the front of the building.
