Physician Assistant · Founder

I am thrilled to bring Therapeutic Elements to life. I am a Physician Assistant and proud Army Veteran with over 18 years of experience in medicine, aesthetics, health, and wellness. My clinical background is uniquely multidisciplinary, bridging Emergency Medicine, Cardiothoracic Surgery, and Neurology. I completed a postgraduate surgical residency in General Surgery, providing advanced procedural expertise and an exceptional understanding of facial anatomy, structural integrity, and skin laxity.

My experience in Neurology has provided me with advanced proficiency in the therapeutic use of botulinum toxins and adjunctive therapies to effectively treat chronic migraines, TMJ disorders, and hyperhidrosis. Additionally, I am highly experienced in supporting patients on their weight-loss and GLP-1 journeys, offering advanced, non-surgical solutions to address skin laxity and tissue remodeling. Through specialized training and hands-on experience with InMode technologies — including Morpheus8 and Quantum — I deliver targeted treatments that restore firmness, improve contour, and enhance overall skin quality.

Therapeutic Elements was created from my passion for blending advanced clinical training with refined aesthetic treatments to deliver exceptional long-term, natural-looking outcomes. My expertise in facial anatomy, pain pathology, and customized treatment planning is what truly sets my practice apart.

Registered Nurse

Hi everyone! I'm Alyssa Hernandez. I was born and raised in Lebanon County and graduated from Cedar Crest High School before earning my nursing degree from Pennsylvania College of Health Sciences.

I've been a Registered Nurse for six years and have spent the last five years in the medical aesthetics industry. Throughout my career, I've gained experience in aesthetic treatments including injectables, lasers, facials, and skin rejuvenation, as well as medical spa operations, team leadership, business development, and clinic management.

What I love most about this field is the unique combination of healthcare, wellness, client experience, and business growth. I'm passionate about helping create environments where clients feel confident, supported, and cared for while building strong teams and fostering meaningful relationships within the community.

When I'm not working, you'll usually find me spending time with my fiancé and my White German Shepherd, trying new restaurants, traveling, enjoying arts and crafts, or simply relaxing and recharging.

ICU Nurse · U.S. Navy Reserve Officer · Aesthetic Nurse

With more than 16 years of nursing experience, including service as an ICU nurse and U.S. Navy Reserve Officer, Ingrid brings a unique blend of clinical expertise, discipline, and compassion to every treatment she performs. Her extensive medical background, combined with a Master's degree in Nursing Leadership, allows her to provide safe, personalized care while helping clients achieve their aesthetic goals with confidence.

Her experience caring for patients in high-acuity healthcare settings and serving in leadership roles within the Navy Reserve has shaped a practice built on precision, integrity, and genuine patient connection. She believes the best aesthetic outcomes come from listening to each client's goals and creating personalized treatment plans that enhance their natural beauty.

As an ICU nurse, Ingrid understands that confidence and well-being go beyond appearance — they come from feeling your best both inside and out. Whether performing microneedling, body contouring, laser treatments, or wellness services, she combines medical expertise with an artistic eye to help clients achieve natural, confidence-boosting results.

Outside of nursing and aesthetics, Ingrid enjoys traveling, strength training, Pilates, and spending quality time with family and friends. She believes that feeling strong, healthy, and confident go hand in hand with looking and feeling your best.
