The best way to get a hold of me is e-mail. You can use the form over on the right hand side of this page or click here to e-mail me at school. If you would prefer to speak to me you can always leave a message on my personal voicemail (847-803-5814), and I will get back to you at as soon as possible.
I am also available on twitter @greichelt. I am always interested in new forms of communication so if you know of a great new way of exchanging ideas let me know and I would be happy to adopt it.
