A doting grandfather warmed hearts after he traveled for nine hours on a bus to watch his granddaughter's college graduation in Texas.

Andrea Morgan's graduation from Texas Lutheran University on May 8 was a moment she will cherish forever.  

But her grandfather's act of support and devotion made it that much more special. 

'Seeing him watch me walk across the stage not once, but twice was incredibly emotional and special for me,' she told NBC 5.

'It reminded me how much family support matters and how proud he is of me.' 

Andrea, 25, told the outlet that her grandfather has never missed a milestone of hers, and this time was no exception. 

At 91 years old, the loving grandfather hopped on a nine hour bus ride and travelled from Chihuahua, Mexico, to watch his granddaughter graduate with her nursing degree in Houston. 

The ceremony marked Andrea's second degree, and her transition from nursing school into healthcare where she hopes to begin her career in women's services. 

'We were taught the importance of health, wellness, confidence and advocating for ourselves from a young age, and those lessons stayed with me throughout my life,' she added in an email to the outlet. 

'Being surrounded by strong female mentors and classmates really inspired me to pursue a career where I could continue supporting women in meaningful ways.'

Andrea added that she was interested in pursuing a career in labor and delivery, postpartum or mother-baby care, with an ultimate goal of becoming a women's health nurse practitioner. 

Andrea previously graduated from Young Women's Leadership Academy in Fort Worth with her sister, Arden, before they both earned their college degrees, the outlet reported.  

The Daily Mail attempted to reach Andrea Morgan for further comment.
