"Dr. Julia is a wealth of knowledge. I'm so happy I found her! I feel like I am able to connect with my body more now than ever before. I plan on teaching my daughters everything that I learned. I wish I would have known these things WAY sooner!"

"Last year, I made the decision to come off of hormonal birth control after 10 years. Learning to track my cycle and use fertility awareness-based methods for birth control was a game changer!" 

- Lauren H

"Cycle Tracking should be required education for everyone who bleeds! I couldn't believe how much I didn't know about my body!"
