“I have known Shelley and Julie in various capacities over the past 25+ years, including working with Julie as my health plan’s CMS regulator and with Shelley as part of my operations and executive team.  Their knowledge and expertise is second to none, and by bringing both the regulatory and health plan perspectives to their clients, they provide effective, thoughtful solutions to some of the most complex compliance issues facing Medicare Advantage plans.  I have engaged MCS on consulting projects and my staff greatly appreciated their insights, observations and recommendations.  I  look forward to working with them into the future!”

Mike Myers

President, President, Health Industry Collaboration (ICE)

“Engaging MCS last year to conduct a compliance program effectiveness (CPE) audit was a great decision. Shelley and Julie helped us design an audit that was very meaningful and also reasonable. Their extensive expertise and experience were apparent throughout the audit and, while they were evaluating our compliance program against the strict CMS requirements, they were highly professional, collaborative and supportive.

The CPE audit confirmed specific opportunities, strengths and best practices of our unique compliance program. We received a high quality final report that included recommendations and benchmarking information to help us continue our journey.

Most importantly, our CPE audit experience with MCS was far superior to our past audit experience with a large consulting firm and provided much more value. We look forward to working with Shelley, Julie and the MCS team in the future.”

Terry Somerville

Director, Compliance Officer, Priority Health

“Medicare Compliance Solutions helped support SCAN Health Plan through a recent CMS Program Audit, as well as a new system implementation, by backfilling leadership duties for our Grievance & Appeals Department. Shelley and her Team provided superb knowledge and skill sets through a risky time period SCAN encountered.”

Patrick Maloney

Vice President of Operations, SCAN Health Plan

“As a Medicare Advantage industry executive overseeing multiple areas requiring quality, accuracy, services and compliance, I have had the pleasure of utilizing Medicare Compliance Solutions on many occasions. Due to the complexities surrounding Medicare’s regulatory and operational challenges, Medicare Compliance Solutions has aided our organization with Stars, Audits, PBM assessments and management support. The combined leadership efforts of Shelley and Julie’s expertise have assisted our company to surpass several obstacles.”

Dawn Maroney

Executive, Alignment Healthcare

“MCS assisted us in preparing for our CMS Program audit including finalizing our pre-audit issues summary, and testing universes prior to submission to CMS, and conducting mock audit sessions. Once the audit was underway, their presence was valuable in supporting us throughout the webinar sessions and providing input where necessary.  The MCS team was professional and collaborative during the audit  and their partnership provided the expert resources needed to provide all information required by CMS during the audit, which often required long arduous hours.”
