Lead Aesthetic Nurse Practitioner

Christina Baronov FNP-C

Christina Bush, FNP-C, is the Co-Founder and Lead Family Nurse Practitioner at KenMi Aesthetics. As an experienced aesthetic nurse practitioner with nearly two decades in healthcare and over five years devoted specifically to medical aesthetics, she specializes in safe, personalized, and evidence-based treatments that help patients look refreshed and feel confident at every age. Drawing on her background as a family nurse practitioner, Christina provides comprehensive care with a holistic perspective, ensuring every treatment plan supports both your appearance and overall well-being. Christina’s clinical expertise includes a full range of medical-grade aesthetics and injectables, including Botox, dermal fillers, and advanced skin rejuvenation therapies. She takes time to listen, educate, and collaborate with each patient so that every injectable treatment and skin rejuvenation service feels comfortable, natural-looking, and aligned with their unique goals. As a military family member and passionate patient advocate, Christina brings warmth, respect, and genuine care to every visit. At KenMi Aesthetics, she is dedicated to creating a welcoming environment where patients feel understood, supported, and empowered to invest in their skin health and confidence through high-quality, medical aesthetics.

Her nursing journey began immediately after high school as a Certified Nursing Assistant before advancing to become a Licensed Vocational Nurse, Registered Nurse, and ultimately a board-certified Family Nurse Practitioner. This unique progression has given Christina a comprehensive understanding of patient care at every level and a deep commitment to clinical excellence.

Christina earned her Master of Science in Nursing, graduating Summa Cum Laude, before completing her Family Nurse Practitioner education at the University of Massachusetts Boston. She also holds a Bachelor’s degree in Criminal Justice Administration from Park University, reflecting her lifelong passion for advocacy, ethics, and patient-centered care.

Before specializing in aesthetics, Christina built an extensive medical foundation caring for patients in the Intensive Care Unit, Post-Anesthesia Care Unit (PACU), plastic surgery, wound care, gastroenterology, pediatrics, hospice, and post-acute care. Her diverse clinical experience has strengthened her critical thinking, attention to detail, and unwavering commitment to patient safety.

For more than five years, Christina has specialized in aesthetic medicine and has extensive experience performing neuromodulator injections, dermal fillers, platelet-rich plasma (PRP) treatments, radiofrequency microneedling, laser hair reduction, medical weight management, skin rejuvenation procedures, and comprehensive facial assessments. She believes aesthetic medicine is both an art and a science, focusing on enhancing each patient’s natural beauty while creating elegant, balanced, and refreshed results.

As Co-Founder of KenMi Aesthetics alongside her husband, Dr. Brian Bush, DO, Christina is committed to providing a luxury patient experience built on honesty, education, safety, and individualized treatment plans. Together, they combine advanced medical expertise with compassionate care to help every patient achieve beautiful, natural-looking results with confidence.

As the daughter of a proud 20-year United States Marine Corps veteran, Christina grew up as a military child and had the opportunity to live in both Virginia and Okinawa, Japan. Experiencing different cultures at an early age shaped her appreciation for diversity, resilience, and service to others. Those values continue to influence the compassionate, individualized care she provides every patient.

Outside the clinic, Christina’s greatest joy is spending time with her husband, Dr. Brian Bush, and their two children, Kenji and Aimi. She cherishes time with her parents—her father, a retired Marine, and her mother, who is originally from Okinawa, Japan—as well as her sister, who proudly serves in the United States Navy. On her time away from practice, she is also deeply devoted to caring for her father as he courageously battles glioblastoma, a condition linked to toxic burn pit exposure during his deployments to the Middle East. She is also an avid animal lover and enjoys life with her beloved pets, especially her Scottish Straight/Bengal cat, Dexie, whom she affectionately considers her best friend.

As a dedicated family nurse practitioner specializing in medical aesthetics, Christina believes true confidence begins with feeling genuinely cared for. At KenMi Aesthetics, her focus is on delivering personalized aesthetic treatments that help every patient look refreshed, feel empowered, and experience exceptional patient care from start to finish.
