Prenatal and pregnancy chiropractic for McKinney moms
Dr. O'Brien is Webster certified and a member of the International Chiropractic Pediatric Association (ICPA). For McKinney moms that means gentle pregnancy chiropractic care adapted to each trimester, in positions that keep pressure off your belly, and given alongside your OB or midwife.
Moms from McKinney come in for:
- Pregnancy back pain
- Pelvic and hip pain as the baby grows
- Sciatica during pregnancy, the sharp pain that runs from the low back down one leg
- Recovery after birth, with postpartum chiropractic
The Webster Technique explained covers what Webster care is and how it works alongside your OB or midwife. The first prenatal visit is $150 with the prenatal new patient special.
Pediatric chiropractor for McKinney babies and kids
Dr. O'Brien sees newborns, babies, kids and teens from McKinney. Every child starts with a conversation and a hands-on exam, babies are adjusted with fingertip pressure, and he works alongside your pediatrician, never instead of them.
The pediatric chiropractor page covers babies and toddlers, and chiropractic care for kids covers school-age children and teens, from posture to sports. Parents also ask about colic and reflux, torticollis and infant constipation; each page explains what a visit looks like. The first pediatric visit is $150 with the pediatric new patient special.
Chiropractic adjustments for McKinney adults
For low back trouble, a stiff neck or recurring 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. Dr. O'Brien looks at how your spine and nervous system are working, not just where it hurts, and works alongside any care from your doctor. The family chiropractor page covers care for the whole family.
Every adjustment follows the INSiGHT nervous-system scans and the hands-on exam from your first visit, so your care plan is built on what Dr. O'Brien finds, not a one-size routine.
