First, let me congratulate your wife for wanting to take the initiative to protect herself. I'm seeing more and more women in our classes who desire the training and knowledge to be able to protect themselves and their families.
I would hope that in your research, you looked at our classes. I think that our Testimonials page speaks for itself (http://proactiveshooters.com/testimonials/) but nonetheless I'm sure that others here will offer their various training experiences.
In the NoVa area, we offer our Basic Firearms Safety class at the Nation's gun show in Chantilly. We actually have some classes coming up there this weekend, Oct. 8 & 9. There's always a good number of women in our classes so she won't feel like she is alone. If she is interested, we are doing a ladies only charity shoot on October 29th at our outdoor range in Doswell, right next to Kings Dominion. There's a sticky in the forum about it. We're going to be doing some light training and some fun shooting activities. It would be a good way for her to get her feet wet and meet other female shooters. We plan to offer a regular ladies only range course in the near future.
Please let me know if you have any questions or if I can be of further assistance.
