Visalia-based Medical Billing Technologies (MBT) has acquired Santa Barbara-based Siras Systems, combining decades of experience in special education program development, documentation and billing under one roof.
Kelly Lingenfelter is president of operations at MBT, the company she co-owns with her brother Reid Stephens. Lingenfelter said the merger creates a more complete solution for school districts that rely on state and federal funding sources.
“Our biggest priority has always been making sure schools are able to maximize their funding and stay in compliance,” Lingenfelter said. “By bringing MBT and Siras together, we’re giving districts a single system that connects documentation, billing and reporting in a way that just hasn’t existed before.”
Founded over 30 years ago by Lingenfelter’s mother, Roberta Stephens, MBT assists rural and underserved schools in navigating special education billing. Siras Systems, developed in Ventura County, grew into a leading provider of software that tracks individualized education plans (IEPs) and other compliance requirements.
The pairing of the two will streamline processes for their client.
“Districts have always had to juggle multiple systems,” said Brian Marcontell, former vice president at Siras and now managing operations under MBT. “This integration means that the data collected in classrooms ties directly to the reporting and billing schools need. It’s going to save educators time and reduce the risk of costly mistakes.”
Both Marcontell and Lingenfelter stressed that the merger is not just about efficiency, but also about student outcomes; with schools facing declining enrollment but a rising demand for special education services, Lingenfelter said the combined platform can help districts stretch limited resources even further.
“We see this as a way to support the teachers and the students they serve,” she said. “The more streamlined the system, the more time and energy schools can put back into the classroom.”
