Dr. Herzog spent five years as an Emergency Room nurse prior to joining medical aesthetics in 2018. She originally went into nursing to help care for patients and contribute to them feeling better. Combining her love for medical aesthetics, inspiring confidence and passion for helping people, Dr. Herzog founded her own practice, Perfect Dose, in 2020.

In addition to her practice, Dr. Herzog also co-founded Perfect Dose RX in 2022; a medical grade skincare line with clean ingredients. When creating this line, her mission was to merge clean skincare formulas with medical grade ingredients that outperform conventional alternatives at an affordable price for all patients.
When Dr. Herzog is not treating, speaking or training, you can find her spending time with her husband, Steven, their son, Jackson, and two chihuahuas; Prince and Pancake.
