Summary
G. Darrell Hulsey has built a career of more than 35 years as an entrepreneur and executive in the healthcare management industry. Since 2016, he has served as the CEO of Professional Billing, Inc. (PBI), where he oversees revenue cycle and practice management services for physician practices across more than 15 states. Under his leadership, PBI supports over 200 practices. Alongside his professional responsibilities, he has been a consistent supporter of philanthropy for more than three decades, contributing both time and resources to organizations and causes he values.
His career began in 1991 when Darrell Hulsey joined CompMed/Medaphis Physician Services, now part of McKesson, as a Senior Operations Manager. Working out of Knoxville, Tennessee, he directed hospital-based physician practices in four states, negotiated reimbursement and contractual agreements with third-party payors, and helped expand new business operations across several regions.
After three years, he co-founded Medical Management Professionals (MMP) with six partners. Darrell served in many leadership positions during his time with the company. In 1998, the business was acquired by CBIZ, where he advanced to Vice President and later President and CEO. When MMP returned to private ownership in 2013, he continued guiding the organization until 2016, when he accepted his current role at PBI. During his tenure with MMP, the company processed over 34 million procedures, managed $5 billion in client charges, and collected more than $2 billion in client revenues. According to SEC filings, the company achieved $165 million in revenue and $21 million in earnings.
At MMP, he worked across all areas of the business, including compliance, operations, IT, finance, HR, sales, and mergers. From 2007 to 2013, while serving as President and CEO, he increased revenue from $90 million to $165 million. Hulsey streamlined 12 billing systems down to four, reduced operating costs by over 45%, and lowered the staff count by about 35%. Earlier, as Executive Vice President of Operations for the East Region, he expanded operations into 10 states, grew revenue by 83%, and increased profits by 98%.
At PBI, he has overseen a 250% increase in revenue between 2016 and 2025. He completed the acquisition and integration of five companies, generating 30% cost savings within 18 months of each. Darrell also introduced advanced data analytics and AI-driven billing systems, reducing claim denials by 25%, improving collections by 15% annually, and lowering administrative costs by 40%. His leadership further strengthened compliance with HIPAA and CMS regulations throughout the company’s operations.
For more than 35 years, he has supported religious charities, donated to St. Jude’s Hospital, and contributed to the Epilepsy Foundation of America. He earned his Bachelor of Science in Health Management with a concentration in Accounting from the University of Alabama and has supported his alma mater for more than three decades.
Born in Haleyville, Alabama, he enjoys fishing, hunting, hiking, and traveling when away from work. Today, Darrell Hulsey continues to lead PBI while maintaining his long-standing dedication to service and philanthropy.
