About Us
Sonoran Serenity Spa & Holistic Wellness Center, a privately owned local business, was founded in 2014 in one room in Downtown Tempe. As the vision of owner and founder Kiera Stroup took shape, she decided that her long-term goal was to establish a day spa and wellness center that was unique in its offerings and inclusive to all. One of the many things that make Sonoran Serenity Spa & Holistic Wellness Center different is the care of the client. Each client is treated respectfully and lovingly by the personal attention given to them during their entire experience. After they are warmly greeted by the receptionist, first time clients are asked to complete an intake form. When they go back for their treatment, time is taken reviewing the information and asking questions to get to know the client and expectations are set for the treatment. Kiera’s concern for the client, as well as her employees, provides a buffer time between each client, so this time is not taken away from the time on the table. For every treatment and service, the client is given their full time. A 1 hour treatment or service = 60 minutes, not 50. At the completion of the treatment or service there is no rush to get off the table. Clients are invited to take their time.

During her tenure, Kiera received her MBA from the University of Memphis while working full-time and raising her daughter as single mother. A native New Yorker, it has always been her desire to live in Arizona. She loves the desert and hiking, and always finds a sense of peace in the beautiful landscape. After deciding to pursue her dream as a wellness professional, in 2013, Kiera left a 27 year corporate IT career, relocated to Tempe, Arizona and enrolled at SWINA, Southwest Institute of Natural Aesthetics where she completed her esthetician training. Kiera continued on to SWIHA, Southwest Institute of Healing Arts and completed the Master Massage Practitioner program, specializing in relaxation massage therapy.
