Cyndi has been the cornerstone of Dr. Mac’s Concierge practice for the last five years. A native Texan, Cyndi grew up in Three Rivers. Cyndi is our master of all trades and makes sure that our thriving practice continues to provide exceptional care and service. Cyndi received her LVN from St. Phillips University. She has had a lifelong passion for nursing and caring for others. She enjoys interacting with patients, keeping up with ongoing education and being a part of our team. She is an avid DIYer and loves tackling home improvement projects in her spare time. Cyndi has four kids and two dogs and is a diehard Dallas Cowboys fan much to Dr. Mac’s dismay.



Quick wit and a passion for providing exceptional care are what make Rhonda, NRCMA, such a vital part of Dr. Mac’s team. She’s a certified phlebotomist with over a decade of experience working in a medical setting. Our patients love her upbeat attitude and quick-fire humor as she works alongside Dr. Mac. Within recent years, Rhonda decided to pursue additional education in medical aesthetics, in particular cosmetic injections. That led her to complete Botox injectables training.  In her free time, she enjoys anything centered around lakes or rivers with a cold drink in hand. She is a gun-toting, BBQ-loving Texan with the accent to match who is raising her three children here in San Antonio.



Kristen is the first smile you see when you walk into our office, and she’s always smiling!  Kristen is a native San Antonian and graduate of San Antonio Christian School who joined us in 2019 to support the continued growth of the practice. As our assistant office manager and receptionist, her responsibilities include scheduling patient appointments, answering telephones, processing payments and receiving communications using the practice’s electronic system. She prides herself on providing the highest level of customer service possible and is always available to answer your questions. Kristen is a Spurs fan with two dogs whom she adores. Her next adventure as a member of our team will be to get her certification in phlebotomy.
