Managing Broker, Ladue Office

As managing broker of the Ladue/Clayton office, I offer a collaborative, supportive and fun workplace for our agents. My highest priority as a manager is to support our agents in expanding their sales and business development skills so ultimately they can reach their goals and live their exceptional lives. In order to help our affiliates realize their highest potential, I offer effective education, coaching, and leadership in this exciting, dynamic, and ever-changing industry. I am a full-time, non-competing broker in order to focus all of my energy on our agents and our office growth.

Having been an agent since 2013 and in management since 2016, I have a strong understanding of the marketplace and the transaction process to help agents navigate any situation to be the best possible advocate for their client. In the Ladue/Clayton office, we have provided representation in some of the highest profile sales in St. Louis County and we work hard to provide exceptional service. Our office is conveniently located right in the heart of Ladue and is close to just about anything in the central corridor. If you are considering a career in real estate or you're seasoned veteran looking for a change, we would love to have you as part of our team of talented real estate agents. Please call Corinne at 314.993.8000 or email Corinne.McGrady@cbgundaker.com.
