Tawni Weaver

Founder and owner of renu medispa

As the founder and owner of Renu Medispa, Tawni Weaver is excited to have opened the first Medical Spa in the Treasure Valley in 2003.

Since then, Tawni has made many remarkable achievements at Renu, including being the only National Council on Laser Excellence certified facility in Idaho.

With a steadily growing clientele of more than 10,000 patients served, including 10% of her clients traveling from out of state, Tawni works tirelessly to ensure that each patient is properly educated and deeply satisfied with the treatments performed at Renu Medispa.

Her sterling dedication, along with her loyal patient following, is a testament to the respect that the community holds for Tawni and her team. It also speaks to the ironclad staying power Renu Medispa has had in an ever-changing and often fleeting industry.

What makes Renu Medispa so exceptional is the philosophy Tawni upholds and adheres to without exception: to be THE BEST. Period. Tawni understands that to be the best, it must begin with her. As such, she has immersed herself in the finest training available in this field.

FNP | Medical Director

Stefani is a highly accomplished nurse practitioner who earned her nursing degree at Boise State University & her masters at Gonzaga University, graduating with honors in 2010. As an advanced provider, she specialized in intensive care and emergency medicine before transitioning to inpatient internal medicine at Saint Alphonsus.

From early in her career, Stefani has been a passionate advocate for healthy living. She firmly believes in promoting a high quality of life through a balanced approach encompassing healthy eating habits, regular exercise, and preventive medicine.

At Renu, Stefani specializes in hormone optimization, thyroid dysfunction management, intimate health and function, weight management, anti-aging and nutritional IV therapy, as well as micronutrient deficiency treatment.

Outside of work, Stefani cherishes her role as a mother to two wonderful children. Her free time revolves around her children’s activities, whether it’s baking goods for a fundraiser or participating as a board member for the PTO and little league. Alongside her husband, Stefani is dedicated to supporting nonprofit organizations that focus on early childhood development, pediatric medicine, and cancer research.

When she’s not working or volunteering, Stefani loves outdoor adventures with her family. Exploring the natural wonders of Idaho is a true delight for them, as they indulge in activities such as biking, fishing, hiking, camping, paddle boarding, river rafting, skiing, snowshoeing, and venturing down backcountry roads.
