About Karen Sheffler

MS, CCC-SLP, BCS-S Download CV

I graduated from the University of Wisconsin-Madison in 1995 with master’s degree in Speech-Language Pathology. There, I was influenced by great mentors in the field of swallowing and swallowing disorders (dysphagia) like Jay Rosenbek, JoAnne Robbins, and James Coyle. Once the “dysphagia-bug” bit, I have never looked back.

Initially, I worked in skilled nursing facilities and rehabilitation centers, but since 1999 I have been in acute care. I obtained my Board Certification as a Specialist in Swallowing and Swallowing Disorders (BCS-S) in August of 2012. I am committed to life-long-learning. I was awarded my 6th ASHA Award for Continuing Education (ACE Award) in November 2018. I am committed to life-long learning and increasing public awareness in dysphagia. I am a member of the Dysphagia Research Society (DRS), the American Speech-Language Hearing Association’s Special Interest Group 13: Swallowing and Swallowing Disorders, and the National Foundation of Swallowing Disorders (NFOSD). I was awarded the Hormel Health Hero Award in 2019.

I started SwallowStudy.com in May 2014 to create a valuable evidence-based dysphagia resource for professionals and patients.

One-Day Live Dysphagia Seminars

Karen provides live one-day seminars on dysphagia for Summit Professional Education, and she was in New Jersey, Minnesota, and New York in 2018. The course is now available online at Summit Professional Education. Course title: ‘What Every Therapist Needs to Know About Dysphagia: Swallowing Screening, Evaluation, & Treatment to Maximize Safety & Quality of Life.’

It is taught at the intermediate level and is a broad-sweep across the field, including: why to be concerned about dysphagia, why and how to advocate for your patients, screening, evaluation, treatment, palliative care/ethical considerations, IDDSI and more. It is designed for SLPs of all experience levels who need to make sure they have the latest evidence-based practices and resources. Karen and Summit encourage OTs and PTs to attend as well for excellent interdisciplinary care. Please notify Summit Education if you have a group interested in a live seminar near you.

3D Printed Pharmaceuticals Summit

Karen presented at the first ever 3D Printed Pharmaceuticals Summit on November 8, 2018 in Livingston, NJ. She was invited to be on a panel titled: 3D Printing of Pharmaceuticals and Biologics to Address Unmet Medical Needs. The conference was sponsored by the Center for Medicine in the Public Interest (CMPI.org) and Aprecia – The 3DP Pharmaceutical Company (Aprecia.com).

Dysphagia is a significant unmet need in traditional drug manufacturing, as people struggle every day to safely swallow their medications. Please see Karen’s blog for more exciting information on how 3D printing will revolutionize what we think of as a finished drug product.

American Speech-Language & Hearing Association (ASHA) in Boston, MA

Karen spoke at the 2018 national convention of the American Speech-Language & Hearing Association (ASHA) in Boston, MA. Together with Theresa Richard, MA, CCC-SLP, BCS-S from SwallowYourPride podcast, she spoke about revolutionizing the old concept that the videofluoroscopic swallow study/VFSS (aka, modified barium swallow study) is the only gold standard for dysphagia evaluations.

When an SLP is thoroughly evaluating an individual’s difficulty with swallowing, it cannot be a dichotomy between just the traditional two exams of the VFSS versus the FEES/Fiberoptic Endoscopic Evaluation of Swallowing. You choose the exam that best fits your clinical questions and hypotheses. Your evaluation process may include one of these exams, both, none, and/or the myriad of other ways to evaluate the swallow with appropriate referrals to our other colleagues in the field of deglutition (i.e., gastroenterologists, otolaryngologists, etc). To reflect this thinking, Karen coined the new term of a “Platinum Standard of Personalized Medicine.”

This means that you are using a personalized medicine approach for you dysphagia evaluations. Your more precise evaluations will lead to targeting treatment to the individual’s needs. Read more on personalized medicine and precision medicine in Karen’s blog.

ASHA COVID-19 Updates / Telepractice

Speech-Language Pathologists and related healthcare providers can stay on top of COVID-19 recommendations by the American Speech-Language & Hearing Association’s (ASHA) by visiting the www.ASHA.org website often. This is a quickly changing pandemic and crisis.

Please also see the “Take Action” links on the ASHA website, such as urging Congress to expand Medicare for telepractice so that people with Medicare DO NOT HAVE TO PAY OUT OF POCKET for basic essential healthcare services, such as monitoring the safety of their swallowing: https://www.asha.org/News/2020/Urge-Congress-to-Expand-Medicare-Telehealth-for-Audiologists-and-SLPs/.

I used Ms. Sheffler as an expert on a nursing home choking death case. Her report was one of the best expert reports I have seen in thirty years of practice. The report was very helpful in getting the case resolved at mediation. She was quick and thorough with her work and it was a pleasure working with her.

What may seem like an insignificant gestures of outreach on your part have contributed so greatly to my professional growth in the past year already - that no amount of praise would be sufficient! The level of advocacy you offer and the breadth and depth of knowledge you possess on this topic is unfathomable.

Anthony Lewis, M.A., CCC-SLP

Thank you very much for your involvement in this case as an expert. Your report was very helpful in assisting the parties in settling the case.

Defense Attorney

I highly recommend Karen Sheffler’s VFSS courses on SpeechPathology.com! Karen’s presentation style was engaging and the information was in depth yet easy to understand. I gained functional knowledge that will improve my clinical decision-making in dysphagia.

Nina Ziemba, M.S., CCC-SLP

Karen’s ability to reach and educate professionals and the public from her review of current literature and conference proceedings helps us all!


Karen has a wonderful way of synthesizing science for clinical audiences. Her ability to communicate clearly and apply scientific results to real challenges in the clinical world is extremely important and goes a long way to filling the knowledge translation gap that scientists face.
