OUR STORY

From Folding Towels
to the Nation's Largest
Founder-Led PT Company.

DPT was built from the ground up, one patient, one clinic, one belief: that the
highest-quality people, doing the most evidence-based work,produce the best
outcomes. That belief hasn’t changed since August 4, 2005.
THE FOUNDER'S STORY

Aaron Kraai Has Been in Physical Therapy His Entire Life

He started at 14, not as a patient, but as the grunt in the corner folding towels. An injury brought him to PT. Two mentors put their arms around him and gave him a shot. By 16, he was scouting locations. By 21, he’d helped open five or six clinics before ever setting foot in PT school.

He went on to earn his Doctorate from USC, the top PT program in the country at the time. After a year at Edward Hospital in Naperville, he decided he could do better. In June 2005, he started treating patients in their homes. On August 4, 2005, he opened the first Doctors of Physical Therapy clinic in Lyle, Illinois. Just him. A mortgaged wedding ring. A Toyota Camry. And a very clear conviction about how PT should be done.

Twenty years later, he’s still here. Still treating patients. Still folding towels when he visits a clinic. DPT is the largest single founder-led physical therapy company in the country , and the only one where every operational role, from CEO to clinic director, is held by a licensed clinician.
IN AARON’S WORDS

"Highest quality people providing the most evidence-based medicine that produces the best outcomes and creates the best value. That's what it is."

WHAT WE BELIEVE

Good Business and High-Quality Care Are Not a Zero-Sum Game

“You can run a good business and still provide high quality care. They’re not opposites. You don’t have to cut corners to be profitable, you just have to hire great people and do the right thing.”
Aaron Kraai, PT, DPT

Clinician-Led at Every Level

Every operational role, from CEO to clinic director, is held by a licensed physical therapist. No business people making clinical calls.

Evidence-Based, Always

Every treatment decision is grounded in current clinical research. We don't chase trends. We do what works, and we can show you the outcomes to prove it.

Transparent and Ethical

Trust is earned, not assumed. We're upfront about cost, coverage, and your plan before we start. No surprises. No pressure.

BY THE NUMBERS

The Largest Founder-Led Physical Therapy Company in America

Most PT companies are owned by private equity groups or hospital systems. DPT is owned and operated by the person who built it, a licensed physical therapist who has held every job in this company, from folding towels to the boardroom.

That matters to patients. It matters to the clinicians who work here. And it means every decision made at DPT is made by someone who understands what happens inside the treatment room.

COMMON QUESTIONS

Questions About DPT

Straightforward answers about who we are, how we started, and how we operate.

Who founded Doctors of Physical Therapy? +

Doctors of Physical Therapy was founded by Aaron Kraai, PT, DPT on August 4, 2005. Aaron opened the first clinic in Lyle, Illinois after earning his Doctorate in Physical Therapy from the University of Southern California, ranked the #1 PT program in the country at the time, and working for one year at Edward Hospital in Naperville, Illinois.

Doctors of Physical Therapy operates 140+ clinic locations across 10 states, making it one of the largest physical therapy companies in the United States and the largest founder-led PT company in the country. DPT has treated more than 100,000 patients since its founding in 2005.

Two things set DPT apart. First, every operational role, from CEO to clinic director, is held by a licensed physical therapist. No other physical therapy company of DPT’s size can say that. Second, DPT is founder-led: Aaron Kraai, who started the company alone in 2005, still leads it today. Most competitors of similar size are owned by private equity groups or hospital systems.

No. DPT is not a franchise. It is a privately held, founder-led company. DPT grows through a combination of organic clinic development and strategic acquisitions of established, community-rooted physical therapy practices, typically small, single-owner clinics with strong local reputations.

No referral is required in 48 states. Patients can schedule directly with any DPT clinic without a physician referral. This is called Direct Access Physical Therapy. Simply call 800-974-4378 or schedule online to get started. DPT accepts most major insurance plans.
