What InHouse Physicians does
InHouse Physicians (IHP) is a privately held US-based healthcare services firm founded in 1992 and headquartered in St. Charles, Illinois. The company delivers on-site medical coverage and wellness services for corporate events, venues, and worksites worldwide, with disclosed operations across the United States, France, Ireland, the United Kingdom, Thailand, Japan, and Puerto Rico. Its customer base includes meeting planners, event organizers, corporate employers, event venues, and large public school systems. The firm reports supporting over 5,000 events and serving 450+ global brands, with a self-disclosed Net Promoter Score of 94.
The company's core technology stack centers on a telemedicine/telehealth platform branded as Asterias Health, which places teleclinics inside corporate facilities staffed by nurses and medical assistants using connected diagnostic devices — stethoscopes, otoscopes, and electrocardiograms — that transmit audio and imaging to remote physicians in real time. The company layers a proprietary "Health Security" framework (Prevention, Detection, Response) over its service delivery and offers add-on wellness modules including a Flow State Virtual Reality Lounge, IV infusion therapy, and pre-filled travel medication kits (RoamRx). Underlying infrastructure includes partnerships with national and regional COVID laboratories for PCR testing turnaround, and an AI/automation partnership to collect patient symptom and physical exam data for diagnostic accuracy.
InHouse Physicians generates revenue primarily through professional services contracts for event medical staffing and emergency response, and managed services contracts for worksite and teleclinic deployments. Pricing is quote-based and not publicly disclosed. Go-to-market is direct enterprise sales supplemented by event-industry partnerships and inbound quote requests, with segment diversification spanning meetings and events (the primary segment), corporate employers and worksites, educational institutions (a non-primary but material vertical driven by COVID surveillance), and event venues. The company has no disclosed outside funding, no parent company, and remains founder-led by Dr. Jonathan Spero.
