What Clients Appreciate About Working With DMD Consulting

Project: Sarbanes Oxley Compliance

Industry: Communication Services/Medical Technology

As the former Senior Director of Internal Controls at Telephone & Data Systems (TDS)/U.S. Cellular I sought out DMD Consulting, LLC to assist with various projects at the time. I worked with Darlene and her firm for approximately 3 years, and I was impressed with their strong technical expertise, innovative approach to improve processes and flexibility displayed during their project.

DMD Consulting assisted our company and my team in becoming fully compliant with SOX. Additionally, they streamlined our internal controls testing, improved operational processes and developed strong and productive relationships with different departments that represent our key stakeholders. I would definitely recommend DMD Consulting to companies looking for highly qualified, seasoned professionals, with a strong sense of urgency who focus on assisting their clients with a flexible and innovative mindset.


Later, as I transitioned to my role as the Senior Director of Internal Audit at Stryker, I once again brought DMD Consulting in to assist my department. DMD Consulting is a high performing consulting firm and delivers top quality work for its clients. Darlene and the other DMD consultants are top notch professionals and are very knowledgeable in GAAP, SOX, internal controls, General IT Controls, and financial reporting. DMD assisted my audit team in completing our audit plan on time, on budget and contributed to having additional reliance from our external auditors. It was great to work with DMD.
