Shawnda Dorantes

Shawnda Dorantes MSN, APRN, FNP-C

Master Nurse Injector & Co-Owner

Acclaimed female entrepreneur, Shawnda Dorantes, MSN, FNP-C (family nurse practitioner) is a master nurse injector, cosmetic tattooist and co-owner of Beauty Lounge Medical Spa, a leading, full-service aesthetic destination in San Marcos, Calif., a suburb of San Diego. A powerful force in the beauty industry for the past 14 years and registered nurse of over 11 years, Dorantes’ tailored expertise and innovative service offerings have paved the way for Beauty Lounge’s proven success. With an impressive 36,000 followers on Instagram, the popular med spa is best known for their non-surgical PDO thread lifts as well as their lip and nose transformations. Beauty Lounge’s service offerings include botox, fillers, laser treatments, microneedling, non-surgical face lifts, body contouring, teeth whitening and results-driven skincare treatments. In 2021, Beauty Lounge won four San Diego Union Tribune’s “San Diego’s Best” Reader’s Poll awards for: “Medical Spa,” “Cosmetic Dermatology Individual: Shawnda Dorantes, MSN, FNP-C,” “Cosmetic Dermatology Office,” and “Day Spa.” A recipient of San Diego Metro Magazine’s “Women of Influence” and “40 Under 40” awards, both in 2021, and listed as a “Best Aesthetic Injector in America” in the National Directory of Recommended Providers, Dorantes is making a huge name for herself both locally and on a national level. In 2021, San Diego Business Journal announced Dorantes as a finalist for two of their prestigious community awards, “Rising CEO of the Year” and “40 Next Top Business Leaders Under 40.” The acclaimed family nurse practitioner has treated thousands of patients including famed reality TV star, Farrah Abraham, Heather Minch of MTV’s “Young Moms Club,” Heather Martin of ABC’s “The Bachelor,” runner-up of season four of “MasterChef,” Natasha Crnjac and many more. Dorantes’ approach is to seamlessly enhance the natural beauty and self-confidence of all of her patients.

The renowned beauty expert’s entrepreneurial spirit was ingrained in her at an early age when she began helping her parents run their family-owned business, and she attributes their guidance to her robust career as a Latina entrepreneur. A longtime former in-demand makeup artist, Dorantes began as a Beauty Advisor for Estee Lauder and later became a freelance professional makeup artist for several other prestigious cosmetic lines. After securing multiple credits in film, print, and television for her work, she then joined Estee Lauder’s Regional Artistry Team while working her way through college. Upon triple majoring and earning baccalaureate degrees in Biological Sciences, Women’s Studies and Nursing from Cal State University San Marcos in 2007 and 2010, Dorantes worked as a nurse in the acute care setting for over eight years and specialized in medical, surgical, telemetry and hospice care before entering the permanent makeup industry and opening Beauty Lounge in 2018.

Since merging her background in cosmetics and nursing, Dorantes has become a licensed and certified cosmetic tattoo artist, has earned her Allergan Master injector certification, and has received aesthetic training in several advanced and masters level injector courses led by famed industry injectors, Kelly Choi NP-C, Rio Calvert, Dr. Gideon Kwok, Dr. Thuy Doan and Erika Berry NP-C. A huge proponent of education, Dorantes participates in ongoing seminars and attends medical conferences throughout the year to stay up to date on the latest non-surgical aesthetic techniques and evidence-based practices. Dedicated to expanding her already well-rounded skill set, Dorantes recently earned her Masters of Science in Nursing in April 2021 from the United States University in San Diego to become a certified Family Nurse Practitioner (FNP). As an FNP, Dorantes provides additional advanced services to her clients, including medical weight loss, medical management of acne, cryotherapy, and more.

Passionate about helping clients regain their confidence, often in less than an hour, the tenacious entrepreneur is driven by the opportunity to mentor and encourage Beauty Lounge’s powerhouse team of practitioners to continuously thrive in the industry. The future for Beauty Lounge includes expansion plans to move into a new state-of-the-art facility in San Marcos in late fall 2021, allowing them to keep up with demand and better serve southern California and beyond. In ongoing support of the San Marcos community, Beauty Lounge supports their local youth sports by serving as a team sponsor and regularly donates to neighborhood football programs. Always committed to philanthropy, Dorantes participated in a medical mission providing medical aide to remote villages throughout Cusco, Peru, with Flying Doctors of America in 2017. A former Team Edge Bikini athlete and health and fitness enthusiast, Dorantes spends her free time hiking, lifting weights, visiting local wineries, traveling and hanging by the pool with her three children, husband and two schnauzers.
