Our History

Advanced Group brings together Advanced Clinical, Advanced RPO, and WunderLand Group. We started in 1988 as a small but mighty Chicago-based staffing agency and over the last few decades have expanded our reach and expertise into new markets and geographies. Operating across the US and Europe, Advanced Group serves our clients and talent across professional disciplines such as technology, finance & accounting, digital marketing, creative services, human resources, office & operations, clinical development, and healthcare. Our leadership team brings together industry experts who lead by example and make Advanced Group a best-in-class, award winning organization.


It is our mission and passion to make a difference, every day, for our clients, our candidates, each other, and our communities. We are dedicated to sharing our time and resources to make this world a better place and do so through our client and candidate relationships, as well as our Community Works programs.


We strive to make our vision a reality: to be the most respected firm in our industry. We may not be the biggest, but that's okay - we find our purpose in how we work and how we show up for our clients, our candidates, and each other. We believe respect is earned and breeds trust. Our aim is to be your trusted partner in achieving your goals.


Our passion and purpose come to life in our REAL values: Respect, Excellence, Accountability, and Leadership. Here at Advanced Group, we Keep it REAL by living our values in all we do. Our culture brings out the best in each of us, encouraging us all to grow and develop, making this an exceptional place to work and achieve great things together.
