About Us

Midtown Medical Group was established in September of 2008 as a local, small business with big aspirations. We began our business focused on providing disability determination services and helping people through the process.

We then grew our team of licensed medical providers and psychologists and expanded across the region to become Nebraska’s top disability evaluation provider.

Still focused on growth, making a meaningful impact in the community, and striving to provide excellent customer service, we expanded our services to include helping companies meet their pre-employment needs.

Over the last 14 years, our mission remained the same – to provide outstanding customer service, ease of scheduling, quick turnaround times, and we pride ourselves in exceeding industry standards in all we do.
