I say this all the time, and I'll say it again. Senior sessions are about so much more than the yearbook photo. Yes, that is an important part, and it's what most people will see. You definitely want to make sure you nail that pic! But your senior photo shoot is more about who you are right now. Seniors are at such a special time in their lives. This jumping off point where anything is possible. Your senior portrait session is the opportunity to tell your story!
Choose a location that speaks to you, or that you love visiting. Wear your favorite clothes. Share with your photographer what is important to you, so they can incorporate that into your session. And most importantly (and I know it sounds cheesy, but...), relax and have fun! 

Jack's senior session started in Cedarburg. We walked around and took advantage lots of great spots we have downtown. There are so many!

He was, uh, obviously, very comfortable with the whole thing.  He drove us to our last location...how could I not capture this??  We choose to wrap up his shoot at a golf course that his family has gone to since he was little. Perfect to catch the last rays of the sun!
