About Advanced Ketogenic Therapies
Our Philosophy
We believe care should be individualized, evidence-informed, and responsive to the whole person—not just a diagnosis.
Our work is grounded in safe, personalized ketogenic metabolic therapy guided by experience, ongoing assessment, and professional rigor.
With compassion and clarity, we develop individualized care plans that reflect each person’s goals and lived experience, while monitoring progress thoughtfully and providing steady guidance and education over time.
Our approach emphasizes collaboration, safety, and adaptability to support confidence, sustainability, and real-life outcomes throughout the ketogenic journey.

Founder Spotlight: Denise’s Story
With over 33 years of experience as a Registered Dietitian Nutritionist—and 17 years dedicated to Ketogenic Metabolic Therapy—Denise has spent her career teaching, training, and supporting individuals and professionals worldwide. In recognition of her leadership in metabolic and brain health, she was named an inaugural recipient of the Metabolic Mind Award from the Baszucki Brain Research Fund.She brings a deeply client-centered approach to her work and has a special passion for helping underserved populations access therapeutic ketogenic interventions safely and effectively.
Advanced Ketogenic Therapies grew from Denise’s recognition that many people were being told to “try keto,” but few were given safe, structured, or research-informed guidance. She founded AKT to change that. Her vision was to create a place where clients could receive personalized plans, thoughtful monitoring, and compassionate support. She believes that when people are guided with clarity and care, meaningful and lasting change is possible.
