At 87 years old, Gladys’ journey is a powerful reminder that exceptional care has no age limit.

St. Catherine’s total joint replacement surgeon, Dr. Gregory Minutillo, recently performed for the first time on Long Island, a complex hip stem Reclaim Monoblock procedure, helping restore mobility and quality of life. The procedure is a new type of hip replacement for revision surgery.

Today, Gladys is recovering well and on her way back to doing the things she loves.

Moments like these highlight the skill, compassion, and dedication of our orthopedic team.

To schedule an appointment with Dr. Minutillo, please call (631) 689-6698.

After 23 years of dedicated service, today we celebrated a remarkable career and an even more remarkable person, Debi Argyros! Having worked in employee health, human resources, as well as infection prevention, many employees looked to Debi for guidance over the years. She will be sorely missed, but will always remain part of St. Catherine’s family!

Wishing Debi all the best in her retirement!
