Lisa Rock


National Medical Billing Services

Location: Chesterfield, MO

Founded: 2003

Industry: Healthcare/Revenue Cycle Management

In 2003, Lisa Rock, a seasoned healthcare executive for nearly 35 years, was diagnosed with relapsing remitting multiple sclerosis. She lost feeling in her hands and feet, had difficulty breathing, was unable to walk, had severe slurred speech and experienced muscular and nerve pain all over her body. After being hospitalized for nearly a month, she lost her job as the vice president of operations for a national healthcare company and was unable to interview for a new position.

With the help of friends and relatives, Rock started National Medical Billing Services, LLC. National Medical Billing Services is the premier revenue cycle outsourcing company focused strictly on ambulatory surgery centers and surgical practices. The firm builds enduring client relationships based on trust and a complete commitment to excellence.

When the firm launched, although undercapitalized, there was a strong need for Rock and her team to earn a living and an even stronger need for the services National Medical provided in the market, said her staff. Facing personal and medical challenges, Rock led the company through growth, ultimately entering into a strategic partnership with Aquiline Capital Partners. Today, the company is the largest ASC revenue cycle management in the United States with nearly 500 employees.

“Lisa’s commitment has always been to provide opportunities and develop employees,” said her staff. “With 1,000+% growth over the past 10 years, she prides herself on being able to consistently develop and promote leaders from within, creating a positive, high-energy company culture.”

For Rock, one of her greatest leadership lessons revolves around knowing her strengths. “I’ve learned to not mold myself into what others think a good leader should be,” she said. “Being authentic and aware, in addition to surrounding myself with talent that complements who I am, instills trust, peace of mind and success.”

Moving forward, Rock said she plans on remaining influential by passing along one of the best leadership skills one can learn in today’s environment – resilience. “Leaders manage a great deal of stress as every single large problem rolls up to them,” said Rock. “A pattern of good judgment is achieved by balancing all input from the team and helping reduce stress. A good leader also knows when to lead diplomatically and when to dictate vision.”

For her ability to find professional and personal growth when faced with adversity, Rock has been named a Titan.
