Meet Our Practitioners
Brooke Bentley | FNP-BC
Brooke Bentley is the founder and owner of Bentley Medical & Aesthetics. She is a Board-Certified Nurse Practitioner specializing in integrative medicine and is a leading provider for cosmetic injections. She welcomes a variety of patients, treating primary care needs and common illnesses, as well as specializing in bio-identical hormone replacement, medical aesthetics, preventative medicine and healthy weight loss.
“Running a medical practice has really given me the opportunity to get to know my patients and earn their trust. Growing a business from the ground up is not easy, but if you can maintain high standards, the clients will keep coming back.”
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. Brooke and her team are passionate about providing a comprehensive, individualized approach to helping her patients optimize and take control of their overall wellbeing and health.
“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.”
Bentley 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. In addition to her work in the Tri-Cities, Brooke Bentley has been a Faculty Member of Allergan Medical Institute™ (AMI) since 2015, training physicians and mid-level providers on the techniques, safety and application of Botox® Cosmetic, Juvéderm® Collection of Dermal Fillers, and Kybella®. 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. In 2018 she was voted “Top 100 of The Best Injectors in America®” by her peers.
“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.”
