There is in theology a term known as "henotheist". That describes a person who works with some deities in particular without denying that other deities exist. This is the category that many Wiccans fall into. As an example, when in circle I work specifically with the Goddess of the Moon and the Horned Lord, but I do not deny tha Zeus, Thor, the Daghda, Kali, and other gods are real. It's just that they are not of immediate concern for me.
When I am in a Wiccan circle I work with the Lord and Lady of the Wica whose names are known only to the initiated of my Tradition.
However, in my personal practice I work specifically with Sekhmet, Tehuti, Anpu, and Menthu. I have a separate altar for them which is different from a traditional Wiccan set up as they are not truly part of my Wiccan practice. There is a picture of my Egyptian altar in my pictures in my profile.
There is an excellent book on the subject of working with Patron Gods called "Devoted To You" by Judy Harrow. I'd highly recommend reading it as I think it will help you a great deal in establishing and maintaining a relationship with one or more Patrons.
