Meet the Staff


COT - Joanne Yawn

See the lady with all that bling and the flower in her hair?  That’s our office manager, Joanne.  She has worked here since the office first opened in Dec 2007.  In fact, she helped Dr Sponsel set up and open this practice.  Joanne has worked in ophthalmology for 30+ years and has been a Certified Ophthalmic Technician since 1988.

Joanne is always in demand as she orchestrates all aspects of the practice.  She puts her expertise to use wherever it’s needed.  Joanne also carries the emergency cell phone and triages phone calls after office  hours and on the weekends.

Joanne LOVES her Dallas Cowboys.  She also enjoys fishing at the coast, spending time with family and doting on her animals at the Yawn Chicken Ranch. 

COA - Kristin Crosnoe

Standing beside Dr Sponsel, diligently writing in the chart is the little lady with the big coif.  Kristin assists the doctor during patient exams and takes notes for the medical record.    This hard-working gal has over 18 years experience in ophthalmology and joined our staff in March 2010.  She is a Certified Ophthalmic Assistant since 2006. 

When Kristin says that she enjoys spending time with family, she isn’t just talking about the human species.  That’s because Kristin is mom to 5 dogs; including 3 beagles and 2 puggles (pug & beagle mix). Yet she still finds time to work-out, plus she and her hubby love to travel.
