NEW YORK, Jan. 18, 2022 /PRNewswire/ — Rethink First, one of the pioneers in behavioral health technology, announced today that it has acquired Total Therapy (previously known as Total ABA), a leading provider of practice management software solutions serving the ABA, speech, occupational, and physical therapy markets. Total Therapy is Rethink First’s fifth acquisition since partnering with K1 Investment Management, a leading investment firm focused on high-growth enterprise software companies.

Rethink First’s current offering, Rethink Behavioral Health, is the leading clinical software solution for ABA service providers on the market, serving over 30,000 clinicians and collecting over 1.6 million clinical datasets per month nationwide. The acquisition allows Rethink to expand its offerings to better serve multi-disciplinary providers caring for patients with developmental disabilities in a rapidly growing market.

“Today, more than ever, people need access to the best behavioral health and wellness solutions and care possible,” said Daniel Etra, CEO and co-founder of Rethink First.  “While we continue to invest heavily in innovation and data analytics, we are thrilled to add market leaders like Total Therapy to our portfolio of solutions. Total has a long history of helping providers and therapists improve productivity and the quality of lives and they are the perfect complement to our current suite of provider solutions.” 

Total Therapy, launched in 2013, is the only therapy solution built on the Salesforce.com platform, offering multi-disciplinary providers a fully integrated system including practice management, data collection, and billing options. Total Therapy now serves nearly 10,000 clinicians and some of the largest behavioral health providers in the country, processing over 2 million billing transactions per year.

Total Therapy’s CEO, Larry Morgan underscored the opportunity saying “We’re incredibly proud of the business we’ve built over the past 10 years and the continued trust that our customers place in us every day. Joining forces with Rethink is an incredible opportunity to more fully address the needs of our clients and the growing behavioral health market, allowing us to further our mission and impact millions of lives.

Jamie Pagliaro, General Manager of Rethink Behavioral Health also provided context for the synergies and excitement behind the acquisition. “The need for behavioral health services is growing exponentially with autism diagnosis growing 20% in just a two-year period and 1 in 6 children now being diagnosed with a developmental disability. Total Therapy allows us to expand our support to service providers, delivering a wider range of therapeutic interventions to this population, helping these individuals receive the highest levels of care.

Certain statements about K1 Investment Management LLC (“K1”) made by portfolio company executives herein are intended to illustrate K1's business relationship with such persons, including with respect to K1's facilities as a business partner, rather than K1's capabilities or expertise with respect to investment advisory services. Portfolio company executives were not compensated in connection with their participation, although they generally receive compensation and investment opportunities in connection with their portfolio company roles, and in certain cases are also owners of portfolio company securities and/or investors in K1-sponsored vehicles. Such compensation and investments subject participants to potential conflicts of interest in making the statements herein. For K1, “carbon neutral” means that any greenhouse gas (GHG) emissions derived from a defined scope of K1’s activities are balanced by an equivalent amount removed, including through our purchase of carbon credits. In this report, our “carbon neutral” status is based on our GHG emissions footprint calculated in accordance with the GHG Protocol as of December 31st, 2023 (comprising Scope 2 Electricity and Gas usage and certain Scope 3 categories: Business Travel and Employee Commuting), amounting to an estimated 3,497 metric tons CO2e. K1 then purchased and applied carbon credits in 2024, amounting to an estimated 6,994 metric tons of CO2e. We engaged a third party to assist with the calculation of K1’s estimated GHG emissions for 2023, but we did not obtain independent, third-party verification of our “carbon neutral” status. To address our 2023 emissions, we contributed to the Conservación y Captura de Carbono / Conservation and Carbon Capture (CO2LTZINGO) reforestation carbon removal project in Coltzingo, Mexico (CAR 1464). This project was certified by the Climate Action Reserve (CAR), using the Protocolo Forestal para México (PFM) Versión 1.5 / Mexico Forest Protocol Version 1.5 and the Guía de Cuantificación de Acervos de Carbono y Monitoreo del Proyecto Versión 1.5 / Project Monitoring and Carbon Stock Quantification Guidance Version 1.5 with a validation date of January 15th, 2019.
