Kristen Herina

APRN, FNP-C, MSN

With more than 15 years combined experience in the fields of nursing and advanced practice nursing, I am both a Family Nurse Practitioner and Aesthetic Nurse Injector. While practicing as a family nurse practitioner, I longed for a work environment that promoted positivity and creativity. I discovered the incredibly unique field of aesthetic nursing. A career that combines my desire to do what I love—learning and discovering new things—with my clinical judgment. Perfect Fit!

Through my advanced knowledge, I am able to create more comprehensive cosmetic plans. This allows the safety and artistry of aesthetics to be upheld.

My practices and skills are guided by integrity and honesty. As Simply Bella has grown over the past several years, we have added a number of nurse practitioners who are committed to the same values and follow the same principles. Our goal is to instill confidence in men and women so they can look and feel their very best.

Brianna Gabbard

Nurse Injector | RN, BSN

I worked as a Paramedic in a prehospital emergency setting for about 14 years. I also spent 3.5 years working as an emergency room nurse. I currently have my Bachelor’s degree in nursing. After a journey of healing when my son suffered a life-threatening medical emergency, I changed some priorities in my life. I personally found a lot of healing in the self-care process and worked to become a nurse injector. I have loved giving men and women the opportunity to feel better about themselves. I want to encourage people through their own healing journeys and self-care, however they may look. I have worked extremely hard in life and try to become the best I can be to give optimal and excellent results. Others would say I am relatable and real. I am a fun-loving person full of compassion and encouragement. In my spare time, I enjoy spending time with my family doing anything outdoors. Overall, I have a love for life and want others to feel great about themselves. I would love to be a part of your journey.

Tiffany Mueller

Nurse Injector | RN, BSN

With over 8 years of nursing experience, much of my career was spent in a hospital setting, working in both surgical units and the GI lab. Though I always had a passion for aesthetics, it wasn’t until 2023, after meeting with Kristen and seeing the incredible environment she has cultivated at Simply Bella, that I decided to take the leap. Since joining the team, I’ve truly found my home in the world of aesthetics. The atmosphere here is warm, welcoming, and focused on safety above all. As an injector, I’m passionate about enhancing natural beauty with results that my clients can both see and feel. My specialties include neurotoxins, filler, microneedling, and skincare. I love building personal connections with my clients, collaborating to create tailored plans that help them look and feel their most confident. When I’m not working, you’ll find me spending time with my family- my husband Chad, our baby boy Ridge, and our boxer Vivianne. Staying active is a big part of our lives- we even own two Muay Thai gyms. We love to travel whenever we can, so I’m always excited to hear about your favorite destinations!

Bridget Dwiggins

Nurse Injector | RN

I am a licensed Registered Nurse with more than 15 years of medical experience in a clinical professional and setting. I went into nursing to make an impactful difference on the lives of others, and I strive every day to honor that commitment. I have had the opportunity to dedicate most of my career to working with new technologies that focus on finding early-state lung cancer, which remains a life threatening and debilitating disease for many across the nation. I have also found a love for aesthetics, and I enjoy watching others light up and build confidence after their treatments. I find it exciting to see small changes make an impactful difference in people’s lives, and I love that I can help play a role in their journey. I joined Simply Bella because I believe in the overall mission of practicing in accordance to safety, artistry and integrity. Simply Bella provides the most up-to-date education and training to their nurses and adhere to a standard of treating others with the highest level of service that is offered in the industry. This knowledge allows me to constantly build upon my skills and treat patients in the most effective way possible. I look forward to meeting you and helping you achieve your desired and deserved look!
