Dr. Nicole Maldonado
Dr. Maldonado was born and raised, right here, in our hometown of San Antonio, Texas. After graduating from O’Connor High School, she attended St. Mary’s University where she received her Bachelor of Science Degree in Biology. Dr. Maldonado then attended the University of Houston College of Optometry in Houston, Texas, where she earned her Doctorate of Optometry Degree. Her training includes externship rotations at the Robert Cizik Eye Clinic at Memorial Hermann Hospital and at the South Texas Veteran’s Administration where she focused on retinal pathology and ocular disease. She loves talking with her patients, relaxing with family, country dancing, vacationing at the beach and last, but definitely not least, Go Spurs Go!
Kristi – Office Manager
Kristi has been with us since July 2010 after suffering through 4 interviews! She started as receptionist and we could not take that anymore so we moved her to the pre-testing room. She wore out her welcome there so we moved her out into the optical styling eyeglasses. So basically, she works in almost every area of the office now! Kristi is a proud mother of a little boy so her spare time is spent with him. She hopes to someday travel outside of Texas. She loves rock music, old and new, like Deftones, Gorillaz, and Led Zeppelin; and loves watching Family Guy. Kristi is a fan of tattoo’s, has 8 and hopes to get more. The more you spend in our optical, the more tattoo’s you will see!!!! She also loves butterflies.
Chad is the coolest member of the staff(in his own mind), joining our awesome team March 2009. He has been in the optical field for 7 years and is an expert at optical sales and eyeglass styling and fitting. Lastly, Tampa Bay isn’t a real football team….Go Cowboys!! Like Dr Nooshin, he also runs many half marathons (again-in his own mind)!
My name is Yvonne, I was born and raised in Laredo TX. I moved to San Antonio 2 years ago and absolutely love it here! I am usually the person that will do all your testing in the exam room before you see the doctor.
I plan on going back to school soon and study nursing. My hobbies are cooking, going to the gym& shopping.
Hi, I’m Nicole. I have been in the optometry field since 2012 but am new to this office in 2017. I enjoy being a part of this business because I always find myself learning something new. My fav part of my job would be patient satisfaction. I believe in treating a patient the way I would like to be treated. Outside of the office, I like taking my daughter on mini adventures around San Antonio, just taking in the beauty around us.
Howdy, I’m Veronica and I’ve lived in San Antonio since age 11. I’ve been an optometric tech since 2008 and love every aspect. My world includes 2 grown boys who are awesome. I enjoy anywhere there is clear blue water, karaoke, live music, and beer.
