John and Mark X. Cronin Address Future Medical Professionals at the University of Houston

Too often, doctors and medical professionals struggle to communicate effectively with patients who have a disability and their families. This can translate into people with disabilities not receiving the care they need. The University of Houston College of Optometry is working to change this situation and they invited John and Mark X. Cronin, co-founders of John’s Crazy Socks, to address a class so they could better understand the needs and experiences of patients and their families.

Muriel L. Martinez O.D., FAAO, Assistant Clinical Professor and Director, Pediatrics and Binocular Vision Service, said, “It is a wonderful opportunity to hear from John and Mark about their experiences in the health care system so our students can better understand how they can meet the needs of all their patients. John and Mark are such compelling speakers.” 

John said, “I think it is important that medical professionals hear from people like me and my family so they can better treat their patients.” 

A Presentation for Optometry Students 

Mark opened the presentation by sharing the experience that he and his wife had when John was born. Instead of doctors congratulating them on the birth of their son, they found out that John had Down syndrome when a doctor told them, “I am so sorry. I have bad news. It appears that your son may have a slight case of Down syndrome.” Mark has written about this experience in an essay published in the HuffPost

The father-son team shared many of John’s experiences with the health care system as he has needed treatment for a serious eye condition – Keratoconus – and hearing loss. In December 2020, John contracted the COVID virus and his breathing deteriorated to the point that he needed hospitalization. John and Mark shared how their local hospital, Huntington Hospital, allowed Mark to stay with John and how that benefited John and the medical professionals and led to better treatment. 

John and Mark also spoke about John’s journey as an entrepreneur and the development of John’s Crazy Socks. Professor Martinez wanted the students to hear about the economic challenges facing people with disabilities as well as their strengths and achievements.

Mark X. Cronin added, “We look forward to speaking with these students. The work they will do in the future will make a difference in people’s lives and the more they understand their patients, the better than can serve them.”
