My company's corporate office is in Lancaster and that's where we're headquartered, but we do serve other regions in PA. We also have a Resource Center you can call for help locating resources in your local area, even if we cannot help you through one of our own programs. Feel free to PM me for our office's phone number or my email, if you'd like us to see if we can help in any way.
Some services, like peer support services through regional Centers for Independent Living, do vary from region to region, in terms of what is available. But, other programs, like the PA Adult Autism Waiver and OVR, are statewide and pretty consistent in what they offer from county to county.
