I suggest starting by finding out if there is already an established Alum. Panhel. in your area. You can find out by visiting
this link, or you can email the advisor for your area, found via
this link. You can contact her, let her know your location, and she will email you and let you know either who to contact, or she can get you started in the process of beginning a new APH.
Feel free to PM me if you have further questions.
ETA: It looks like you'll want to email Carol Coordt. If there is not an APH in your area, you'll want to contact Lisa Keathley. Hope this helps!
