Located in the Western Suburbs of Chicago, Castello Wellness is taking a new approach to medicine. Here, we don't just treat the symptom. We treat the whole individual to achieve optimum health and happiness. Building relationships with patients is rewarding and results in better health outcomes for patients. Castello Wellness was founded by Dr. Gregory Castello on the principle that wellness takes many forms, and only through a combination of best practices and individualized treatment plans can we truly help our patients. At Castello Wellness, Dr Greg Castello brings 20 years of experience to the table. Along with his physician assistant, Erin Valentino, they work together to provide personalized care to their patients.
Dr Gregory Castello, DO

Dr. Greg Castello has been practicing as a board certified family physician for 20 years.  He graduated Midwestern University as a Doctor of Osteopathy in 1993 and finished his residency at MacNeal Hospital in Berwyn, IL in 1996.  After residency, Dr. Castello practiced medicine at various clinics and finally decided to open his own private practice in 1999. By opening his own practice, he was able to dedicate more time to his patients and build long term relationships with them.  Dr. Castello also has extensive experience as an urgent care and immediate care physician. In 2012, Dr. Castello received specialized training in bioidentical hormone replacement for men and women. He has since incorporated these new skills into his family practice.  He also incorporates his own interests into the practice. Dr. Castello is an avid athlete and stays up to date with nutrition and fitness recommendations. He guides his patients to healthier lifestyles by sharing his own personal knowledge in order to help them reach their wellness goals.
