At anniversary dates it is always fun to look back and see where we have been. Through 20 years of steady growth,  the firm’s founders and those that have followed have worked hard to not only be financially and professionally successful but more importantly to maintain a culture that supports and satisfies the needs of our diverse team of professionals. So much has changed since SL+Co opened for business but throughout those years the constant has been the core group of values that drive our everyday decisions. We are proud of the first 20 years and are very excited about the next 20.

– Bart Lanman, Managing Partner
