Some careers move through a series of employers. Others deepen inside a single institution until the two become difficult to separate. Cresta Duin’s belongs firmly to the second category. For twenty-three years and five months, she has worked at St. David’s HealthCare in Round Rock, Texas, and in that time she has layered specialty upon specialty onto a single, steady occupational therapy career.
Today, Cresta Duin holds the title of Senior Occupational Therapist at St. David’s HealthCare, a role she has held since May 2003. Around that core position, she has built additional areas of specialization, each one adding a new dimension to the kind of patient she is equipped to treat.
Certified for the Hardest Cases
Cresta became a Certified Lymphedema Therapist in May 2005, a credential she earned through specialized lymphedema training, making it the longest-running of her specialty certifications. Lymphedema, a chronic condition involving swelling caused by impaired lymphatic drainage, can occur after cancer treatment or surgery and requires specialized clinical knowledge and skills. Cresta’s more than two decades of experience in the field have made lymphedema care one of the defining areas of her professional practice.
In October 2014, she added a second specialty credential, becoming an LSVT BIG Therapist, a certification tied to a structured movement program developed to help people with Parkinson’s disease and other conditions affecting movement. She held the credential through 2020, adding movement-focused rehabilitation to an already expanding clinical skill set.
Her focus sharpened further in November 2017, when she earned an Oncology Rehabilitation Specialist credential, bringing cancer rehabilitation more directly into her scope of practice and joining oncology care with her established expertise in lymphedema and movement therapy.
Teaching Beyond the Clinic
Cresta’s expertise has not stayed confined to St. David’s. Since March 2007, she has worked as a Contract Trainer for Tactile Medical, a company known for its lymphedema and compression therapy devices, helping educate clinicians about technologies used in the management of chronic swelling and lymphedema.
Her teaching has also extended into formal academic settings. In October 2015, she served as a Professional Expert Guest Lecturer at the University of St. Augustine for Health Sciences in the Austin, Texas, metropolitan area, where she lectured on Axillary Web Syndrome techniques in rehabilitation and lymphedema care, a condition marked by cord-like bands of tissue that can develop under the arm after breast cancer surgery or lymph-node removal.
A Practice Built on Depth, Not Breadth
What stands out across Cresta’s career is not the number of employers she has worked for; there is really only one, but the number of distinct competencies she has folded into that single role. Lymphedema certification, movement disorder therapy, oncology rehabilitation, contract training, and guest lecturing all sit under the umbrella of one Senior Occupational Therapist position at one hospital system, built patiently across more than two decades.
It is, in its own way, a rebuttal to the idea that career advancement requires constant movement between institutions. Her growth has been vertical rather than lateral, each new certification and area of expertise added without ever needing to leave St. David’s HealthCare or the Round Rock community where she has built her career.
A Steady Hand in a Demanding Field
Cresta’s career offers a particular kind of proof: that depth of experience, sustained over decades inside one system, can be just as transformative as a career built across many institutions. Her work has centered on lymphedema and oncology rehabilitation, while her broader occupational therapy experience has also included movement-focused care.
Twenty-three years in, her specialty credentials and clinical experience in lymphedema, oncology rehabilitation, and movement therapy tell the story of a clinician who treats her own scope of practice as something to keep developing, patiently and continuously, over time.
