Meet Our Staff


Nancy Guenthner, OD
Developmental Optometrist

Dr. Guenthner (pronounced "Get-ner") received her Bachelor of Science degree with High Honors from The University of Texas at Austin.  She was involved in many activities during her undergraduate years, including playing clarinet in the Longhorn Band and serving as secretary for Tau Beta Sigma, an honorary service sorority for college bands.  Her passion for service continued at the University of Houston College of Optometry (UHCO), where she was actively involved in Beta Sigma Kappa, an optometric honor society, and the College of Optometrists in Vision Development, an organization dedicated to vision therapy.  After graduating Summa Cum Laude from UHCO, Dr. Guenthner returned to the Central Texas area to begin her career.  Dr. Guenthner is a proud member of the Central Texas Optometric Society, American Optometric Society, the College of Optometrists in Vision Development, and the Optometric Extension Program Foundation.   

Dr. Guenthner’s interest in vision therapy began before she even entered optometry school when her younger brother successfully went through an optometric vision therapy program for amblyopia, or "lazy eye."  Dr. Guenthner has completed over 100 hours of continuing education dedicated to expanding her knowledge in developmental vision and vision therapy. 

Dr. Guenthner lives in Round Rock with her husband, Chris, their two cats, Rusty and Scarlet, and their cocker spaniel, Sunday.  When Dr. Guenthner is not taking care of her patients, you can usually find her and Chris at any Longhorn sporting event.  Dr. Guenthner believes it is essential to establish a strong doctor-patient relationship so every patient feels comfortable and cared for.  She looks forward to meeting you and your family! 


Chris Guenthner
Business Manager

Chris was born and raised in Austin, TX.  He received his Bachelor of Music degree from the University of Texas at Austin and has taught private trumpet lessons to high school and middle school students.  Chris has performed with many local symphonies including the Austin Symphony Orchestra, Austin Civic Orchestra, and Round Rock Symphony.  He also has completed financial planning courses through the University of Texas to help prepare him for his role as business manager of Aspire Vision Care.

When not at work, you will most likely find Chris either watching or attending any Longhorn sporting event.  Since Chris is a fourth generation Longhorn, he definitely bleeds orange!  If it’s not football, basketball, or baseball season, Chris also enjoys spending time with his wife, Dr. Guenthner, their two cats, Rusty and Scarlet, and their cocker spaniel, Sunday.
