Peter Del Buono, FNP-C

Peter Del Buono has been a part of the First Primary Care team since day one.  His path into medicine began with a passion for physical activity and an interest in human physiology. He began with an undergraduate degree in exercise physiology and worked as a Division I collegiate strength and conditioning coach while pursuing a masters degree in sports psychology. After seeing friends and loved ones struggle with maintaining their health, his interest shifted from elite athletes to helping everyday people live their healthiest lives.

Peter then began a fifteen-year transition from a peak performance specialist to a board certified Family Nurse Practitioner (FNP). He obtained his BSC in Fitness and Human Performance from the University of Houston Clear Lake. He then went to the University of Texas Medical Branch for his Bachelor of Science, Nursing as well as his Masters of Science, Nursing.

As Peter puts it, becoming a Family Nurse Practitioner was the best choice that he’s ever made; it’s rewarding and enjoyable to be a key part of people’s efforts to achieve and maintain better health.

In his free time, Peter enjoys trying new restaurants around the Houston area and traveling.

Cassandra Wertz, MD

Dr. Wertz’s patients know her to be empathetic, happy, and dependable. While she enjoys the variation that primary care allows, she is passionate about treating anxiety, depression, weight management, and preventative care.

Since her earliest memories in kindergarten, Dr. Wertz has always known her calling to be a physician. She went on to become a graduate of UT Austin, UT Health Science Center at San Antonio School of Medicine and trained at Baylor College of Medicine.

Outside the clinic, you can find her alongside her high school sweetheart husband and spunky daughter, Sophia, probably walking their two dogs. They keep busy riding bikes, playing games, attending plays, musicals, and Astros games. After all that, Dr. Wertz makes time for watercolor painting (although allegedly not very good at it), cheering on the San Antonio Spurs, and preparing her favorite snack—a bagel loaded with lots (and lots!) of cream cheese.

Now accepting new patients, Dr. Wertz loves the process of getting to know people on a deeper level and helping them navigate the problems that arise through life.

Chi Stasio, DO

Dr. Stasio is a board-certified family medicine physician who graduated from Texas College of Osteopathic Medicine. She loves taking the time to connect and care for her patients and enjoys the freedom of providing quality care on her own terms.
On her time off, she’ll be hard to find, but you can look somewhere between airports where she’s bound to be photographing the world. But being family-oriented, she always finds her way back home to Houston to snuggle up with her husband and beloved corgi, Ollie, in their home theater. Ask her what’s next on the to-do list, she’s always got one, and coffee with oat milk is definitely at the top of it.
