Terry Gerling

Susan Gerling – Owner, Licensed Salesperson, and President

Susan (Sue) Gerling is the Owner of Ultimate Realty. Susan's late husband, Terry, started out in real estate in 2007. He worked for many years as an agent before getting his Brokers license in 2012. Once Terry earned his Brokers license, he immediately founded Ultimate Realty in May of 2012. Terry very rapidly grew Ultimate Realty into a one-stop shop Property Management and Real Estate Company servicing the greater St. Louis area. Ultimate Realty offers the full package for their clients which is something Terry takes great pride in.

Sue took over as Ownership of Ultimate Realty in May of 2023 and has been an active employee since May of 2012. Running a business is not new for Susan. She has many years experience in corporate America as well as she grew up herself in a family owned and operated business, just as Ultimate Realty is today.

In her free time, Sue enjoys spending time with her granddaughters and spending time at the Lake of the Ozarks with family.


Lisa Miller

Lisa Miller - Broker and Director of Operations

I was born and raised in St. Charles County. I attended the University of Central Missouri before transferring back home and finishing my schooling at Lindenwood University. I have been with Ultimate Realty since May of 2012, the day it opened. I am the one who oversees the day to day operations in the office. I take pride in communicating with our clients and enjoy spending time getting to know our owners and tenants as well as our home buyers and sellers. I enjoy watching baseball, swimming, and spending time with my 3 beautiful daughters. On the weekends, you can typically find us at one of the softball fields around town as I am also a select softball coach.

I am also a licensed salesperson as of August 2019 and in May of 2023, I obtained my Brokers license. 

Maggie Colegrove

Maggie Colegrove – Assistant Director of Operations and Licensed Salesperson

I joined the Ultimate Realty team in October 2016. I began as an office assistant and work my way up to Office Manager and then to Assistant Director of Operations. I graduated from Lindenwood University with my Bachelor’s Degree in Business Administration. Outside of work, I enjoy spending time with my boyfriend Adam. I also enjoy spending time with my family. My brother lives about five doors down, so I am constantly over there hanging out with my nieces and nephew. In my free time, I love spending time outdoors, shopping, and watching Netflix/YouTube. I also enjoy taking adventures to new places around the Saint Louis Area. I am excited to be on this journey with Ultimate Realty and experience everything as we continue to grow.

Jim Richmond

Jim Richmond - Broker Salesperson

I was born and raised in the St. Louis area. I graduated in 1985 from Ritenour High school. I first worked for the old Overland Dairy grocery stores where I eventually was promoted to cashier and fell in love with running the register and playing with money. After high school graduation, I started a full-time job with Midwest Library service while also keeping my job at the grocery store. Since working with money was what I enjoyed most I applied at St. Johns Bank where they hired me as a teller in 1986. I worked the next 27 years learning everything I needed to know about banking. I was a teller, trainer, personal banker, asst. manager, and eventually a Branch Manager. I wore many hats as a manager including opening accounts consumer loans, customer service and managing other employees. My career in banking ended in January 2013 where I then met Terry. We had several conversations and he persuaded me to pursue a career in real estate. I’m glad to be in the real estate industry and plan to help grow this company as best as I can. I acquired my Brokers license in February of 2017.
