First in Tampa Bay to offer LLLT technology
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.
Computerized, gentle adjustments — no popping, no twisting, no discomfort. The Impulse iQ delivers precise force tailored to your spine. And you keep your clothes on.
FDA-cleared Low-Level Laser Therapy. Dr. Marcy was the first in Tampa Bay to offer this non-invasive treatment. No heat, no discomfort — just deep tissue healing.
