CEO, Principal

Greg is your business brain. He often says that “providers have enough to worry about. Administration and running a business should not be one of them.” His career began in finance and accounting at one of the big investment firms. But he quickly found his home in the healthcare industry where he has made it his personal mission to bring competent and trustworthy executive-level management experience to providers who want to take their practices to the next level.

A few of the things he’s learned along the way: Work hard and do what you say you’re going to do. Communicate well with your clients. Work every day to relieve business headaches so your clients can love what they do. And treat every practice as if it were your own.

VP Revenue Cycle Management, Principal

Janet’s tenacious spirit will become one of your greatest assets. The philosophy she’s lived by for the past 30 years is simple: Every provider deserves to get paid for what they do. And she makes sure that this core belief is internalized by every one of her employees. To further enhance her accounts receivable department, she has dedicated an entire department to coding. She optimizes reimbursement from insurance companies, and ensures all claims are sent “clean” the first time.
