Sabrina Balloun


Registered nurse, Sabrina Balloun was born and raised in the Houston area. After receiving degrees from both Texas A&M and The University of Texas at Houston she pursued nursing in acute care. After years in acute care, she was presented with an opportunity to venture into the aesthetic industry by a physician she worked alongside.

She also prides herself on continuing to learn the most innovative, safest techniques in cosmetic injecting by working one-on-one with many of the leaders in the industry and attending detailed courses. For Sabrina, this is not a job, it is a passion, one she would love to share with you when you come in for your first consult!

In the office to see our provider’s and you hear “HI DOLL!” down the corridor? You found Kaitlin! Best friend to Sabrina herself, and Team SI’s first employee (humble brag), Kaitlin was practically born for this role. Throughout her professional career, Kaitlin has always been a manager in some way, shape, or form. In addition to management, Kaitlin brings over 12 years of experience as a makeup artist to the team–holding a ton of insight into the beauty and cosmetic industry!
An energetic, “people person” Kaitlin is passionate about Team SI and it’s patients’ experiences–always ensuring that the level of customer service and standards of interactions are extraordinary for everyone. Not only does she take pride in managing the day-to-day practices of the team, she oversees the in-house Marketing team. When Kaitlin first started working with Sabrina she found herself tweaking and playing with her Instagram for fun…she never guessed that a few years and some dedicated Instagram time would lead to 50,000+ followers and patients from all over the country!
In her free time you can find Kaitlin “managing” her kiddos at home or working on assignments for class as she is currently pursuing her business degree.



A “jack of all trades” is the best way to describe Operations Manager Casey. New to the world of aesthetics (but not medicine), Casey’s background is in Family Practice and Cardiology. A day in the life with Casey is one that’s hard to keep up with! From helping our scheduling team answer calls, to walking patients back to the procedure rooms, translating–yep she’s fluent in English and Spanish!–numbing patients for their procedures, and of course making sure Sabrina is always running on schedule.
Casey is one of the friendly faces you’ll see in the office after your check in with our front desk team, and one of the last you’ll see before you leave because she loves seeing everyone’s transformations. Call her your hype girl, Casey’s favorite part about her job is getting to see how happy patients are with their services at the end of their visit. If you ever get the pleasure of having a conversation with Casey you won’t regret it, she always wants our patients to feel comfortable and have the best experience possible!
When she’s not in office keeping all the providers on schedule you can find Casey spending time with her family and adorable pets–2 Labradoodles and an Australian Shepherd.

Want to know where our TikTok and Reels come from? Desiree is the one to thank for those! You can always count on Des to convince our providers to recreate a funny dance or skit she saw on TikTok the night before.
