About Dennis D. Koonce: Attorney at Law
Real Estate Attorney in Frankfort, Illinois
With strong ties to the mortgage industry, I was inspired to follow in my family’s footsteps and help people through complex real estate matters. I earned my Juris Doctor from California Western School of Law in 1984 after graduating from Eastern Illinois University with a Bachelor’s degree in Business Management. This combination of legal training and real-world mortgage experience gives my practice a unique perspective and helps me serve individuals and families throughout Frankfort, Illinois, the surrounding communities, and all of Chicagoland.
How I Can Help With Your Real Estate Matters

Navigating legal challenges on your own can create unnecessary stress and risk—especially when the outcome affects your home, finances, or future. With over 40 years of experience in real estate law and real estate finance, I understand the details that matter and know how to guide clients through the process with confidence. I’ve been a solo practitioner and business owner for more than three decades, and I’m proud to bring that experience to every client I represent.
Whether you’re buying a home, selling a property, refinancing, or working through a dispute, I can help you navigate each part of the real estate process. From contract review and negotiation to closing, my goal is to protect your best interests from start to finish. I also offer guidance in mortgage origination, helping clients understand their mortgage terms and find solutions that fit their goals.
My professional background includes representing buyers and sellers in real estate transactions, serving as a title insurance agent, conducting title examinations, drafting title commitments, and issuing title policies. Over the years, I have closed hundreds of loans in my role as an attorney, title closer, broker, and lender. I have also worked with respected mortgage banking institutions, including The Federal Savings Bank, Chicago Bancorp, and American Portfolio Mortgage.
No matter what brings you to my firm, you’ll work directly with me throughout the entire process. I believe in open communication, reliable guidance, and making sure you always understand your options.
