Brooke

Bentley

FNP-BC

Brooke is the Founder & Owner of Bentley Medical & Aesthetics. She is a Board-Certified Nurse Practitioner specializing in integrative medicine and is a leading provider for cosmetic injections for over 17 years. Brooke is a member of The American Academy of Anti-Aging Medicine and makes it a priority to stay current in the industry’s most recent, innovative treatments and cutting-edge research. She stays a step ahead by offering hormone replacement therapy to both her male and female patients, giving everyone the opportunity to Look, Live, and Love Better.

“One of the perks of working in integrative and anti-aging medicine, is treating patients who are proactive about their overall, long-term health. Rather than simply treating symptoms, I am able to really get to know my patients and together we develop the best plan for optimizing their health and vitality. I love treating hormonal issues because it can make a huge difference in someone’s life. The same goes for weight loss; it is very rewarding when someone who is unhappy with their weight can come in and get the physical and mental treatment they need to feel better about themselves and become healthier at the same time. It is truly incredible to witness our patients improve their quality of life, and live happier, healthier lifestyles.”

Brooke has earned an exceptional reputation in the field of cosmetic injections. She has trained with some of the most renowned experts in the industry and is known for her skillful and subtle technique. Most recently, she has trained extensively with Dr. Yan Trokel on YLift®, an advanced, non-invasive facial contouring procedure, and is excited to be the first in the region to provide this progressive new treatment.

Passionate about teaching, Brooke has also gained recognition as a National Trainer for Galderma and travels around the country sharing her techniques and pearls of wisdom with other practices and professionals. Her accomplishments have been recognized as Brooke had the honor of being named one of the Top 100 Best Aesthetic Injectors in America® for 2024.

“Every single patient is different! I absolutely love being able to celebrate and enhance my patients’ natural beauty, giving them the confidence to put their best self forward each day. I am proud of the trust that my patients give me in helping them age gracefully with cosmetic injections, but I also preach the importance of a quality skincare regimen. I see it as an investment in yourself.”
