Founder & Owner

Jamie Wurth,
FNP-C

Jamie started her advanced practice nursing career in pre-operative medicine. After 12 years as an advanced practice registered nurse, she founded Simply Wurth It to give patients something she saw missing in healthcare: real support, real accountability, and real results through safe, medically guided weight loss. Her main focus is the health and wellness of her existing and future clients — because she believes everyone is worth it.
