Julie Oswald, Productivity Coach - Plainfield

 Brian’s goal is to help others and keep it simple. 

When Brian entered the employment world, he had a plan: to join the world of Law Enforcement and help others “hands on”. But after a career spanning 20 years that plan came to an abrupt end when he was injured in the line of duty. 

Police work had always been a deep love of Brian’s and the only career he saw himself in. He had become a specialist as a training officer, member of SWAT, motorcycle officer, and evidence technician. 

When faced with a permanent career ending injury, Brian opted to steam roll through all of the difficulties that came with this scenario. He focused on the positive and dove in, creating new opportunities. 

Within a span of 3 years he has:

- Started “Grizzly Plowing” using the four-wheeler he always loved; 

- Developed his passion of photography, became a Drone Video and Photographer, and established “Front Line Drone Photography”; and

- Became a Licensed Real Estate Broker, joined Keller Williams Realty Infinity and established “Front Line Homes”, which allows him to use his love of helping others and real estate. The positive culture and teamwork drew Brian to KW and as part of the team Brian has become a: 

- Member of the Social Committee;

- Member of the Annual Octoberfest Committee with aspirations of becoming part of the leadership team; 

- 3x BOLD Grad and was a Team Leader for the 2nd year BOLD Team;  

- Military Relocation Professional (MRP), Negotiation Expert (RENE), Capper (100% Commission); and 

- TOP AGENT in the Market Center for 2019. 

Even as Brian learned to become an agent, he helped other agents along the way. Now, as a Launch Coach Brian will use the combination of his skills and talents to help YOU efficiently launch and succeed! 

Happily married for 18 years, Brian and Janice are the proud parents of Brooke, age 17, and Alexis, age 15. 

The joy of knowing that you have made a positive impact in someone’s life is beyond words.

Tammy Rodrigues, Managing Broker - Aurora

When I joined Real Estate in 2006, my goal was to help others understand the process in buyer or selling their home. So many of them have a misconception of what an agent does for them. Since I have always been the nurturing type I found that this filled my soul. It allowed me to aid my clients and give them the tools to understand real estate. I am blessed with being able to build strong relationships, while educating, and teaching others along with a service that goes above their expectations.

Having compassion and willingness to listen and hear what others needs and wants are a fulfilling part of my life. Plus, I get to provide a helping hand to their family and friends. My passion is leading others through a successful journey and providing them with my expertise and knowledge.

I enjoy spending time with my family having five children and seven grandchildren are a blessing from above. Taking time for them and guiding them through life’s challenges has made me who I am today.
