Mark D. Esarey, O.D.
Originally from Crawford and Lawrence Counties in southeast Illinois, Dr. Mark Esarey received his A.A. degree from Vincennes University, his B.S. degree from Indiana University, and his O.D. degree from Indiana University School of Optometry. He is a past president of the Charleston Area Chamber of Commerce, Charleston Kiwanis, Coles County United Way, Coles County Council on Aging, Eastern Illinois Optometric Society, and Illinois Optometric Association.

Dr. Esarey sponsors and has coached multiple youth sports, and is a frequent area acoustic musician and vocalist. He is also an amateur astronomer and Harley-Davidson enthusiant.
Darcy L. Duzan, O.D.
Dr. Darcy Duzan was born and raised locally in Oakland, Illinois. She received her Bachelor’s Degree in Biological Sciences from McKendree University. In 2006, she graduated from Indiana University with honors as a Doctor of Optometry. While there, she served as an Associate Instructor for several courses and was a member of the Beta Sigma Kappa International Optometric Honor Society. Immediately following her graduation, she joined Lifetime Eye Care and has been thoroughly enjoying her career at the practice ever since.
While providing exceptional eye care is a must, Dr. Duzan also believes excellent patient communication and education is equally important. “I strive to make sure my patients understand their conditions so they can be active participants in their eye and health care.” Dr. Duzan enjoys seeing patients of all ages for routine care, as well as, managing ocular diseases including, but not limited to, glaucoma, cataracts, macular degeneration and dry eye disease. She is trained in the fitting and management of both soft and rigid contact lenses, including multifocal lenses.
Dr. Duzan also has a special interest in Low Vision services. These services help patients with impaired vision from eye diseases such as macular degeneration, glaucoma, diabetic retinopathy, retinitis pigmentosa, cataracts, vision issues related to albinism, and more, to maximize their remaining vision. This is done with the help of highly specialized Low Vision optics/glasses and other vision aids that help patients regain their independence.
Giving back to the community is also important to Dr. Duzan. She currently serves on the Mid- Illinois Big Brothers Big Sisters Board of Directors. She is a longtime member and past president of the Charleston Rotary Club. She has also enjoyed serving on the Coles County Health Department Board of Directors. In her free time, she enjoys cooking, running, and most of all spending time with her family.
Derek B. Hennig, O.D.
A Charleston native, Dr. Derek Hennig joined Lifetime Eye Care in the Summer of 2017. He received his Bachelor of Science degree in Biology at Indiana State University and his Doctor of Optometry degree from Southern College of Optometry in Memphis, Tennessee. While in Optometry school, he received numerous educational and clinical awards before graduating as Valedictorian of his class. He was an active member of Beta Sigma Kappa International Optometric Honor Society, the Contact Lens Society, the Optometric Private Practice Club, and the Fellowship of Christian Optometrists, participating in mission trips to both Haiti and Nicaragua.
Dr. Hennig manages many forms of ocular disease, including but not limited to glaucoma, macular degeneration, dry eye, cataracts, and keratoconus. He enjoys researching new topics in eye health management, but ultimately loves interacting with new people and building new relationships. “My goal is to not only provide quality care, but to also make sure patients know that they play a vital role in their own healthcare. The best care takes place when the doctor and patient establish an open and honest communication line that allows for both parties to develop an appropriate plan of care that is tailored to that individual.”
Dr. Hennig takes a particular interest in specialty contact lenses, including scleral lenses, for the treatment and management of ocular disease, as well as advanced dry eye evaluation and management. Utilizing treatments such as the new, state-of-the-art Tear Care system for in-office dry eye therapy, he is able to provide extensive dry eye treatment for patients suffering with dryness.
Outside of the office, Dr. Hennig serves as a diplomat of the Charleston Area Chamber of Commerce and is the current President of the Eastern Illinois Optometric Society. He also serves on the Executive Council for the Illinois Optometric Association. At home, he enjoys spending time with his wife, Lauren, and their three children, Noah, Clara, and Adelynn. He is an avid St.Louis Cardinals fan and loves the outdoors.
