About our company

Periscope’s expert, objective, and timely assessments provide clients the information they need to make accurate decisions.

What do we do?

Founded in 1998, our company emerged as a specific solution to a single client pain point.

In 2008, the company incorporated as DME Consulting Group, Inc. (DME-CG), which then focused on a value-based delivery model for medically vulnerable individuals that drove cost-effective medical decisions for our health plan partners. Thanks to our team’s dedication to excellence and our clients trust in our ability curate solutions to areas that matter most, we have significantly expanded our service offering by expanding our clinical expertise and clinical disciplines. Our growing national team of licensed clinical consultants and reviewers now cover over 23 million lives and approach 100,000 completed assessments in all fifty states.

Periscope’s expert, objective, and timely assessments provide clients the information they need to make accurate decisions.

Our dynamic team works closely with clients to understand their needs, desired outcomes and assist in a course of action. Our expanded service portfolio and collaborative approach lead to great opportunities to tailor solutions unique to our clients.
