Our Doctors

At Spex Expressions we know what it’s like to trust someone with your vision. Selecting an eye doctor can be a process, especially when you worry about the eye care of yourself and your children. For these reasons Spex Expressions considers the eye care of our patients to be our primary concern.


Dr Frank practices full scope optometry by providing treatment and management of ocular diseases, hard to fit contact lenses, and cutting edge dry eye therapies. Dr Frank continues to be on the forefront of new technologies.

Dr. Jeffrey Frank graduated from Indiana University with a degree in Chemistry and went to graduate school at the Illinois College of Optometry (where he met his wife and partner, Dr. Kristy Marczewski, which, he says, was “the best decision of my life”).

Dr. Frank graduated with honors from the Illinois College of Optometry and is a member of Beta Signal Kappa honor society, the Illinois Optometric Association, and the American Optometric Association.

Dr. Frank enjoys running and being with his family, and is a big fan of Indiana sports – college and professional.

As an eye care professional, he believes that giving the gift of sight to his patients is a blessing, which is why he chose to open a vision center center in Sycamore, IL and dedicate his life eye care. Dr. Frank has been practicing since 2003.


Dr. Kristy Marczewski is a Chicago native who did her undergraduate studies at the University of Illinois in Chicago. Like Dr. Frank, she also decided to dedicate her life to eye care, and earned her her postgraduate degree at the Illinois College of Optometry. Dr. Marczewski has extensive experience in contact lenses, pediatrics, ocular disease, and pre-and post-op LASIK.

Dr. Marczewski is also a member of the Illinois Optometric Association and the American Optometric Association, and has a passion for the care of her patients as well as development of long-term relationships with them.

When she’s not dedicating time to her patient’s eye care, Dr. Marczewski enjoys spending time with her family, exercising, watching movies, and just being outdoors.

As an optometrist, she likes making a difference in her patient’s lives – seeing their faces when they realize how they should have been seeing the world with corrected vision. Dr. Kristy Marczewski has been practicing since 2004.
