Annika Kariniemi is a highly experienced Family Nurse Practitioner with a diverse background in healthcare. She began her career as a Registered Nurse in 2010, dedicating 8 years to working with patients recovering from bariatric surgery. In 2018, she earned her Nurse Practitioner certification and transitioned to a busy family practice, where she witnessed the devastating impact of obesity on her patients daily.

Seeking to make a greater difference, Annika moved into wound care, where she once again faced the challenges associated with obesity. Throughout her career, she observed the transformative effects of medical weight loss on her patients’ health. Motivated by these positive outcomes, Annika decided to focus her expertise on weight management. She founded Activ8 Health, where she is committed to helping individuals achieve their health and wellness goals through personalized, medically supervised weight loss programs.
