Oasis OB/GYN!!! They're located on Power and Brown in the Hershey plaza. I realize it's not the west side, but it's only a 30 min drive for me and I live out in the San Tan Valley/Queen Creek area.
Dr. Messer is great though! Delivered both my girls. I do suggest you get morning appointments though if possible. Afternoons are often really busy and can have long wait times. It never bothered me to wait since I realized that it was because the NP's and Dr. Messer were taking their time with the patients and not rushing anyone!

Good Luck and Congratulations!!!!
