Amplify Clinic

Our Incredible Healthcare Professional

Yana Khilkevich

MSN, APRN, FNP-BC

Yana is the founder and lead practitioner at Amplify Clinic. As a Family Nurse Practitioner, she has been caring for patients with both acute and chronic conditions since 2022.

She founded Amplify Clinic with a focus on perimenopause, menopause, men’s health, and weight management — inspired in part by her own health journey. Her areas of focus include bioidentical hormone replacement therapy (BHRT), testosterone replacement therapy (TRT), and weight management.

With years of prior experience in aesthetic medicine and injectable treatments, Yana has returned to her passion for aesthetics and now offers these services at Kamyar Kamjoo, MD’s practice in Tarzana. Her clinical knowledge, attention to detail, and artistic eye guide her approach to neurotoxins and dermal fillers, with a focus on enhancing each patient’s natural features and creating subtle, balanced, refreshed results.

Before becoming a Family Nurse Practitioner, Yana spent a decade in nursing, with experience in hospital operating rooms and home health. Her diverse clinical background has shaped her personalized and thoughtful approach to patient care.

At Amplify Clinic, Yana believes in building lasting relationships with her patients and creating individualized treatment plans that support both health and confidence.

Outside of the clinic, Yana enjoys spending time with her husband, three daughters, and their beloved dog.
