As president of Visiant, Jamie Wells is focused on providing market-leading solutions and offering exceptional client delivery, while concentrating on growth, operational excellence and culture.

His years of experience in senior executive and healthcare roles, along with a history of delivering results via innovative solutions, make him well-suited for this role.

"We are operating in an exciting marketplace and will execute our growth strategy to position Visiant as a strong competitor in not only the Medicare Advantage market, but the Medicaid and Commercial ACA markets as well," he said.

Jamie's breadth of business development and information technology experience played an integral role in the creation of Visiant and its sister company, Tessellate, in January 2017. In his previous role as president of Data Driven Delivery Systems (now Tessellate), Wells was responsible for leveraging strategic opportunities to drive revenue growth and position the company as a trusted comprehensive solutions provider for health plans.

He also served as president of Verisk Health's revenue and quality intelligence division. While there, he improved operational efficiency, helped achieve an annual revenue growth of more than 50 percent, and contributed to a customer retention rate of 98 percent.

Maria Calcaterra is a highly skilled healthcare compliance, process management and operations executive. She currently serves as managing director of business administration for Visiant.

A certified professional compliance officer and HIPAA privacy and security expert, Maria has more than 25 years of experience designing and managing risk controls to align with business objectives, regulatory requirements and risk tolerance.

Prior to joining the Visiant team, she served as chief compliance officer for Data Driven Delivery Systems. She previously held the position of chief compliance officer and vice president of quality for Verisk Health.

Maria has both domestic and international experience, having worked in India and Nepal. She also spent four years as the managing principal of an independent consulting firm in Lyon and Paris, France.

Outside of work, Maria is an accomplished cyclist, having won several Virginia state titles like Women's Road Race Champion and Masters Best All-Around Champion.

She earned a bachelor's degree in applied biology from the Georgia Institute of Technology.

As Visiant's chief operating officer, Rob Galan manages the company's front- and back-office business process outsourcing solutions, technical operations, and operations management services.

Prior to joining the Visiant team, Rob served as a vice president of operations within Optum, managing call and claim centers, utilization management, eligibility, training and quality. In addition to launching a concierge-focused service model, he was a founding member of OptumCare, a division focused on helping healthcare providers deliver quality care via integrated delivery networks.

Previously, as director of operations for Massachusetts-based insurance company Tufts Health Plans, Rob oversaw call and claim centers, as well as training and quality. He held various operations management roles in his seven years at Oxford Health Plans, now part of United Healthcare. While there, Rob ran call and claim centers, worked to integrate acquisitions and launch satellite offices in New York, Connecticut and Florida.

Throughout his more than 20 years in the healthcare industry, Rob has earned a number of Stevie Awards for excellence in sales and customer service.

When he's not working, Rob enjoys spending time with his kids – attending their softball, baseball and basketball games. He serves on several local organizations' boards of directors for youth programs and veteran needs.
