Before founding Vanguard in 2012, Tiffany gained valuable experience in clinical research through  roles such as Research Coordinator, Clinical Research Associate, Clinical Trial Manager, and Director of Clinical Operations at various CROs and pharmaceutical/biotech companies.

Her passion for bringing life-changing treatments to patients in need drives her ambition to cultivate the “white glove” caliber service at the core of Vanguard’s offerings.

In her personal life, Tiffany is a devoted wife and mother of four who finds joy traveling the world, racing cars, and collecting vintage wines and first edition literature.

Director, Clinical Operations Mary Liscar is a dedicated clinical research professional with a diverse skillset which formed during her time serving in the U.S. Air Force. Mary graduated from the U.S. Air Force Academy in 2007 with a B.S. degree in Social Science and earned her MBA from Colorado State University in 2011. Her adaptability, adept leadership and dynamic critical thinking translated seamlessly from the Air Force into the clinical trials industry, where she started as a Clinical Research Specialist in 2016. Prior to that, Mary worked for a leading medical device company on the commercial side.

Her career followed a traditional clinical operations path where she held positions such as Clinical Research Associate and Clinical Trial/Study Manager at various medical device/biotech companies. Mary joined the Vanguard family in 2020 and assumed the title of Director, Clinical Operations in January 2023.

Her reason “why” is what drives her each day: to facilitate the advancement of the clinical development process to bring curative/impactful treatment options to patients and their families, with the ultimate goal of providing meaningful contributions to healthcare.

In her personal life, Mary is a devoted wife and mother of two toddlers who values quality family time and work/life balance. She enjoys CrossFit (occasionally competing at local events!) and spending time with her family in the Texas hill country.

Director of Clinical Data Management & Biometics Jamie Parker began her career in the laboratory first working as an Environmental Chemist and then as a Microbiologist focused on pre-clinical and post-market research and testing. Three years into her career, she began searching for opportunities to learn more about the clinical trial side of her work. This led to an opportunity to work under an amazing Head of Clinical Data Management and from that point she hasn’t looked back.

Now with 20 years of Clinical Data Management experience, she is just as passionate about her work as she was on her first day. Jamie mentors others interested in Clinical Data Management as well as those wanting to understand how Clinical, Data Management & Biometrics must align to accomplish successful studies. She is also continuously working to ensure Clinical Data Management and Biometric service offerings are top of the line white glove for each client. She believes fast and efficient are important; however, data efficacy, quality, and subject safety must never be sacrificed.

As a new empty nester, Jamie enjoys date nights with her husband. However, she is still figuring out what to do with the rest of this new free time.

A clinical research leader that leverages her broad breadth of experience spanning over 20 years in pre-clinical/clinical research, including monitoring, clinical study management, and management and mentoring of clinical team members at all levels.
