Matthew Billingsley
Owner & CEO
Matthew Billingsley is the Owner and CEO of Jack + Jill Aesthetics in Franklin, Tennessee, where he has helped build a practice centered on thoughtful treatment planning, conservative results, advanced technology, and long-term patient relationships.
With experience spanning both the clinical and business sides of medical aesthetics, Matthew serves as a Medical Assistant, Certified Laser Technician, and Laser Safety Officer. His hands-on knowledge of aesthetic technology, patient care, practice operations, and treatment planning gives him a unique perspective on what patients should expect from a modern medical aesthetics practice.
Since entering the aesthetics industry, Matthew has remained focused on one core philosophy: the right treatment is not always the most aggressive treatment, and sometimes the best recommendation is no treatment at all. At Jack + Jill Aesthetics, patients are encouraged to make informed decisions based on their individual anatomy, skin condition, goals, lifestyle, and long-term results rather than short-lived trends or social media hype.
Matthew has helped guide Jack + Jill Aesthetics into a comprehensive medical aesthetics destination offering injectable treatments, advanced laser and energy-based procedures, body contouring, medical-grade skincare, skin rejuvenation, hair restoration, wellness services, and other non-surgical aesthetic treatments.
He is especially passionate about laser safety, proper patient preparation, treatment protocols, education, and investing in proven technologies that can produce meaningful results while maintaining patient safety as a priority.
Under Matthew’s leadership, Jack + Jill Aesthetics has built its reputation around a straightforward approach to aesthetics: educate first, treat conservatively, recommend what is appropriate, and never perform a treatment simply because a patient asks for it.
Matthew believes aesthetic medicine should help patients look refreshed, healthy, and confident while still looking like themselves. That philosophy continues to shape the patient experience at Jack + Jill Aesthetics today.

Kaylee Whittaker
Medical Aesthetician & Laser Technician
I’m a Licensed Aesthetician and Certified Laser Technician who has been practicing aesthetics since 2024. I have a genuine passion for skincare, skin correction, and helping people feel confident in their skin.
I began my education at Aveda Institutes in Franklin, Tennessee, where I developed a strong foundation in skin health, professional skincare, and the science behind aesthetics. Since graduating, I’ve continued to grow my knowledge through hands-on experience and specialized training, with a particular interest in corrective skincare and laser technology.
My passion for this work is also deeply personal. In my early 20s, I had severe cystic acne and know firsthand how much a skin concern can affect your confidence, your comfort, and even the way you move through your everyday life. With the combination of medical treatment and a holistic approach to supporting my overall health and gut, I experienced the incredible connection between what is happening within our bodies and what we see on our skin.
That experience continues to influence the way I care for my patients today. I believe in taking the time to understand each person’s skin, goals, and needs. My goal is always to create a thoughtful treatment plan that not only addresses what we see today, but supports the long-term health and integrity of the skin.
My background in personal training has further shaped my approach. I’ve always been fascinated by how the body works and by the idea that we can partner with our bodies by giving them the care, support, and nourishment they need. I carry that same philosophy into skincare and aesthetics.
I’ve also had the privilege of owning my own aesthetics practice. While I’m incredibly grateful for everything that experience taught me, I ultimately chose to close my practice and join a team environment where I couldn’t be happier. I feel incredibly honored every day to have the trust of the patients I care for.
At the heart of everything I do is a desire to care for others and is one of the reasons I love this career so much. Being an aesthetician allows me to combine my passion for skin health while also creating a space for people to feel cared for, heard, and confident.
Thank you for trusting me with your skin and allowing me to be part of your journey. If we haven’t met yet, I can’t wait to meet you, get to know you, and care for you.
