Meet Dr. Marcy

Dr. Marcy Smurthwaite has been in private practice since 1994, serving Pinellas County with gentle, computerized chiropractic care. A native Floridian and certified laser therapy specialist, she was the first doctor in Tampa Bay to use Cold Laser Technology. Her philosophy is simple: medicine alters body function. Chiropractic restores it.

When she's not in the clinic, you'll find her cooking organic food with her husband Robert, fly fishing in North Carolina, or on a missionary trip treating her Mayan friends in Mexico.
