In a time where we are seeing overall start-up timelines increase, she can move mountains and help navigate the nuances of site start-up so we can get sites open quicker for enrollment.

As a proven expert in expedited SSU, her close ties with PIs and cancer centers worldwide enable precise trial-to-site matching.

As she built the Oncology Site Network for Precision for Medicine, I witnessed firsthand how she consistently delivered results while bringing an infectious enthusiasm to every project. What is particularly impressive is Tandy's talent for not just creating robust professional networks, but activating those relationships to achieve meaningful objectives.

Her longstanding relationships with cancer research centers, developed through years of experience, were instrumental in helping us efficiently overcome these obstacles.

    Clinical Project Manager, U.K. Biotech

  • Having worked with Tandy in a previous organization, I didn’t hesitate to reach out for her advice and support as we faced the complexities of launching a new oncology study in the US and EU. Tandy's deep expertise in oncology site networks was not just helpful but absolutely instrumental in our success. She guided us through every detail, from identifying ideal clinical sites to streamlining the process for site selection, study start-up, and contract negotiation. Tandy’s strategic insights ensured we partnered with the best-equipped sites, helping us achieve our first-patient-in (FPI) milestone on schedule. Her support went far beyond logistics; Tandy’s personal and professional relationships with sites set her apart. She has an unmatched understanding of the clinical trial landscape globally, knowing the specific strengths and capacities of sites not just in the US and EU but worldwide. Her relationships are mirrored by the sites’ responsiveness, making every interaction seamless. I highly recommend Tandy for any oncology clinical study start-up or ongoing site management. Her commitment and the value she brings are invaluable at every step.

Burning Questions about Winniedel

  • No. In fact, there is less risk, no revolving door of change orders, reduced costs, greater dependability, reduced timelines and 100% transparency. We partner with smaller and more “niche” CROs, with whom WD has long-standing relationships with the founder/CEO and who have deep experience in oncology across all phases and therapeutic indications. The transition from us to our CRO partner is seamless, and we continue to manage the sites and work with the CRO to mitigate and prevent site issues that could negatively impact the trial. We have relationships all over the globe and can “plug and play”; thus, if you need a full-service CRO after SSU or various FSP providers, we have your back!


  • We perform FIH to Phase 2b plus IITs and across any and all therapeutic indications in the cancer ecosystem, including radiopharmaceutical trials.


  • Yes, but if a sponsor wants Winniedel to take over (rescue) the SSU of a trial that was with another CRO prior we will do it only if the sponsor decides to stop working with the CRO that made the “mess”, and that they decide to work with one of our partner CROs and, or FSP partners for all activities after SSU; thus, for the duration of the trial.

  • We put our money where our mouth is, and will always be transparent with you. Our team and our partner CROs and FSP “provider hub” have extensive global oncology expertise and the sponsor is an extension of our “team”. Everything that we do is for the sole purpose of getting potential life-saving cancer treatments to patients faster; We tell it like it is; no smoke and mirrors; no to having a sponsor sign on the dotted line and then 30 days later having a change order with no end in sight; long-standing and “close” relationships with sites, PIs and KOLs; optimized SSU methodology and a global oncology site universe that rocks!
