Regardless of what you may have heard on SDN about WesternU, I want to clarify that it is one of the best OMS in the country. Many OMS boast about serving the underserved, but COMP actually does that, especially given its location.
The MSMS program is hard. I will admit that we are examined under a microscope all year. With that being said, you do in fact learn about being a professional. From the way we are dressed, to the way we are supposed to speak, we are being groomed for the DO program, because when it comes down to you vs. another applicant, this is what is going to give you the edge. The DO program here is great, and from what I've heard from the former MSMSers/now OMS-Is, they love it. They really feel that MSMS prepared them to kick butt during first year. In fact, my friend just posted a photo of the honor society for COMP OMS-I, and a good chunk of the MSMSers that matriculated made the honor society.
IF you have doubts, I suggest you do a bit more research OUTSIDE of SDN, as I feel that some people on SDN can be quite toxic.
