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.

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.
