Meet The Providers

Kelly Eyer, FNP-BC

Owner, Market Street Medical, LLC

Kelly has been an Olney resident nearly all her life. Though she began her career as an elementary teacher, her love for learning and caring for others inspired her to pursue a career in advance practice nursing.  She worked as an OB/Nursery nurse for several years, then went on to obtain her Family Practice degree from Frontier Nursing University. 

In 2015, with the help of her husband, Greg, she began her private practice, Market Street Medical. It is her passion to be able to connect with patients and their families in her community, so that when they leave the office they know that they have been offered a listening ear, a sincere prayer, and a superior plan of care for whatever challenges they are experiencing.

While she provides primary care to patients of all ages, her interests lie in women’s health, mental health, chronic diseases, and weight management.  She is married to Greg Eyer and has 5 children: Hannah, Trevor, Dalton, Gloria & Olivia, and 1 grandchild, Grant.  She loves spending time with her family, going camping, singing, playing bari sax in the Cummins Band, and is very active in her local church.   She relies on her faith in Jesus Christ daily, for guidance and direction in her practice and in life.

“There will always be a reason why you meet people; either you need them to change your life or you’re the one that will change theirs” is a quote which has defined how Jamee practices medicine and views the people she has the honor of caring for.  Growing up in Jasper County, she proudly calls Newton her home, although she happily spends the majority of her time in Olney. Along with her husband and children, she enjoys binge watching paranormal Netflix series, traveling to state/national parks, and eating good food. Along with home life and clinic life she also volunteers her time in the fall as a Junior Football League board member and cheer co-coach.  Jamee started her nursing profession 20 years ago and was fortunate through family support and personal dedication to become a Family Nurse Practitioner in 2011.
