Princeton was the fastest-growing city in the country in 2024: the U.S. Census Bureau counted 37,019 people there in 2024, up 30.6% in a single year[1]. If your family is one of the many that moved in recently, you may still be looking for a chiropractor. More and more of the new patients at Trinity Life Chiropractic drive in from Princeton, to one office in downtown Allen where Dr. Colton O'Brien is a Webster-certified prenatal chiropractor and a pediatric chiropractor for babies and kids.
There is no Princeton branch. From most of Princeton the Allen office is about 25 to 30 minutes away: west on US-380 to McKinney, then south on US-75.
How far is the Allen office from Princeton?
The office is east of US-75 in downtown Allen, on N Allen Dr just south of the St. Mary Drive roundabout.
- Take US-380 (Princeton Drive, which becomes University Drive) west into McKinney.
- Merge onto US-75 (Central Expressway) south toward Dallas.
- Exit at Exchange Parkway / Allen Drive (exit 36) and follow the service road to Allen Drive, which leads into downtown Allen as N Allen Dr.
- Go straight through the roundabout at St. Mary Drive. The office is the red-brick plaza just past it on the right (west) side, with free parking at the door.
To skip part of US-380, you can also turn south on Airport Drive in McKinney, take SH 5 (McDonald Street) south and join US-75 at Spur 399. It takes about the same time.
| Starting point | Route | Approx. minutes | Notes |
|---|---|---|---|
| West Princeton (Monte Carlo Blvd) | US-380 west → US-75 south → exit 36 → Allen Dr | 24–28 | About 15.5 miles |

Pregnancy and new moms
Dr. O'Brien is Webster certified, and pregnancy care is gentle, focused on the pelvis and planned alongside your OB or midwife. After delivery, postpartum chiropractic supports the back and hips while a new mom recovers.
Babies, kids and teens
Visits for children use light, low-force contacts, with a parent close by. The pediatric page above covers newborns and toddlers, and chiropractic care for kids covers school-age children and teens, from posture to sports.
Parents
Parents from Princeton come in for back pain, neck pain and headaches. See our back pain chiropractor, neck pain chiropractor and chiropractor for headaches and migraines pages, and sciatica for leg pain that starts in the low back. The family chiropractor page covers care for the whole family, which works alongside your own doctor.
What happens at the $150 first visit
The new-patient special is $150 (regularly $350) and follows the same steps for every age, so one trip covers what you need to decide on care:

- Three INSiGHT nervous-system scans.
- A hands-on physical exam.
- A first adjustment, if it's appropriate that day.
