About Tiffany Serell

With over 10 years of experience in customer service, health and wellness, and project management, I am a Client Success Manager at Simplicity Consulting, a leading provider of on-demand marketing and business solutions. I support the maintenance and growth of a $4.8M ARR book of business with key accounts in Fortune enterprise tech and healthcare, including AWS, Meta, Intel, and Providence. I exceeded 2023 revenue goals by 34% and managed a portfolio of 40+ projects from Statement of Work through Project Closure. As a certified Health Coach and Yoga Instructor, I also leverage my skills and passion for wellness to offer positive lifestyle changes for mental and physical growth to both clients and consultants. I partner with the Client Success Manager to provide quality service, strategic insight, and solution-oriented collaboration to our Strategic Account clients. I am driven by the mission of delivering exceptional customer success and satisfaction, while creating a positive work culture by setting clear expectations, providing excellent collaboration, and delivering efficient, quality work. I am resourceful, detail-oriented, adaptable, and influential in my role, and I thrive under pressure, overcoming setbacks by setting and achieving goals.
