Our team has years of experience assisting and advising both buyers and sellers of commercial investment properties.  Our transaction experience ranges from single tenant net lease investment sales to large grocery anchored shopping center sales.  As a company, we are proud of our strong history of bringing together buyers and sellers of high quality investment properties and coordinating deals that are financially beneficial to our clients.

We have worked on both sides of transactions with clients that have ranged from small local investors to large REITs.  We have the investment experience, contacts, and market knowledge necessary to drive real value to our clients in investment transactions.


We work with high quality tenants throughout Missouri and Illinois. Our tenant representation services include:

Market Analysis

Competition Mapping

Site Selection

Financial and Risk Analysis

Coordination of RFPs, LOIs, Contracts, and Leases

Lease/Purchase Negotiations

Our market knowledge, connections to area landlords, and deal negotiation experience make us a great partner for tenants looking to expand their reach, relocate a location, or renegotiate a current lease.


We partner with property owners to help them fill their vacant spaces.  Our long history of experience, market knowledge, and focus on the St. Louis and Central/Southern IL markets help us to add real value to our client's businesses.


Our connections with high quality tenants and their representatives and our knowledge of the current tenant landscape in the area allow our team to effectively and efficiently help our clients find tenants for their property.


Our years of experience helping our clients purchase, sell, master plan, and develop their land make us an ideal partner.  Our connections with brokers, developers, government officials, and other key players allow us to help our clients find the perfect piece of land to fit their needs or to find the right buyer for the land they already own.

Our job doesn't stop when the buyer or seller is found.  We help our clients navigate the entire process - from identifying a buyer/seller, to the entitlement process, to closing - we will work hands-on with every client to ensure that the transaction is as smooth as possible and that their goals for the deal are met and exceeded.
