Company profile
researched Sep 2026FlexTogether is a telehealth clinic providing virtual pulmonary and respiratory rehabilitation for people with chronic lung conditions including COPD, interstitial lung disease (ILD) and long COVID. Care is delivered entirely online through video appointments with physical, occupational, respiratory and speech-language therapists, combined with self-directed home exercise programs. Patients are evaluated at an initial appointment and receive a personalized program spanning breathing exercises, strength training, flexibility, balance training, yoga, dance, chair yoga, cardio and qi gong, with sessions of roughly 30-60 minutes and multiple difficulty levels including seated options. Programs can be paused or modified, and a maintenance program is offered, including for graduates of traditional in-person pulmonary rehab. Providers are described as board certified with experience treating older adults and additional respiratory training, and the company says it coordinates with patients' other physicians.
The service is delivered through a browser-based website rather than a downloadable app, works on Mac and PC across Chrome, Safari and Edge, requires a webcam, and is designed to function in low-bandwidth settings. Classes are currently offered only in English. The company positions the offering as a turnkey virtual pulmonary rehab solution that independent medical groups can deploy as a billable service line to expand their practice footprint and patient access. FlexTogether distinguishes its model from traditional pulmonary rehab by billing for physical therapy and speech-language pathology and using different providers and care delivery methods, while drawing on pulmonary rehab best practices.

Founding story
Co-founders Emily Mischel and Benji Rostoker met as graduate students in the Master of Science in Social Entrepreneurship program at USC Marshall School of Business. Mischel was inspired by her grandmother's recovery from lung disease and came from a healthcare family after earlier work in casting, video production and financial services; Rostoker brought software development and caregiving experience. Their initial concept focused on exercise, social connection and isolation among older adults, developed with partners including the AARP Foundation. After Rostoker's father was diagnosed with a chronic lung disease, the team researched pulmonary rehab, identified low patient access to an evidence-backed intervention, and pivoted to a virtual pulmonary rehab practice designed for homebound patients.

▸Full profile — market position, technology, go-to-market, geography, history
Market position
FlexTogether operates in virtual pulmonary rehabilitation, an area the company frames around low utilization of an established intervention: leadership cites less than about 4% of Medicare patients accessing pulmonary rehab despite evidence of reduced hospitalizations and improved quality of life, and a target population of roughly 37 million people with chronic lung disease in the U.S. [4]
The program is delivered entirely virtually with no in-person therapy, uses a multidisciplinary provider mix (physical, occupational, respiratory therapists and speech-language pathologists) rather than the traditional pulmonary rehab staffing model, emphasizes engaging class formats such as dance, yoga and qi gong, offers scheduling within a week without waitlists, and requires no equipment or software download. [0][2]
Technology
A browser-based telehealth platform requiring no download, supporting video visits on Mac and PC via Chrome, Safari and Edge, requiring a webcam, and engineered to work in low-bandwidth conditions; classes are not available offline. [2]
Go-to-market
Sales are directed at MD groups and independent medical practices that can deploy the turnkey program, supported by a consumer-facing website with phone-based consultation booking and scheduling within about one week of inquiry. [0][2]
Patients with chronic respiratory conditions — including COPD, ILD and long COVID — many of whom are older adults or homebound, reached through independent medical groups and physician practices that deploy the program. [0][2][4]
Geography
Headquartered in Los Angeles, with service areas listed across counties in Florida and Vermont. [0]
History
The company was founded to expand access to respiratory care, evolving from an older-adult exercise and social connection concept developed during the founders' USC graduate program into a virtual pulmonary rehab practice. Its program was designed by a multidisciplinary team including physical therapists, speech-language pathologists, respiratory therapists and pulmonologists. In May 2025, co-founder and CEO Emily Mischel discussed the company's origins and model on the Xceptional Leaders podcast. [2][3][4]
