Thank you, Mark. Good afternoon and thank you for joining us today for IsoRay's fiscal third quarter 2020 earnings conference call for the quarter ended March 31st, 2020. Following my comments, our Chief Financial Officer, Jonathan Hunt will provide a more detailed review of the fiscal third quarter financial results. I am very pleased to share with you the considerable progress, we continue to experience at IsoRay and the accelerated growth we realized in the quarter ended March 31st. Record revenue for the third quarter increased 50% versus the year ago quarter. This quarter comprised the top three single highest revenue months in the company's history. We continued to see substantial operational improvements in this quarter as gross margin expanded to a record 59.2%. Combine that with moderate operating expense growth, and we significantly decreased our operating loss, which was half of what it was in the fiscal third quarter of 2019. A central factor in driving strong momentum that is manifested in our financial results is our growing leadership role within the brachytherapy industry. We continue to expand our role as a trusted, valuable partner, enabling more practitioners to better treat their patients. This is evidenced again this quarter by yet another increase in new customers. As of the trailing 12 months ending March 31st, our net new physician customer count increased 33% versus the previous 12-month period. We continue to gain traction by highlighting the unique benefits of Cesium Blu and our supporting delivery devices. In addition, our best-in-class customer service and support and our expanding digital presence should allow us to continue to grow our leadership position. As we ended the quarter in March, the world saw a significant shift from the unfortunate implications of the COVID-19 global health pandemic. I am proud to report that from the onset, IsoRay has been proactive in implementing plans to ensure the health and well-being of our employees, while remaining focused on providing uninterrupted product flow to the physicians and patients who count on us. We seamlessly transitioned many employees to work from home and made other adjustments to ensure the continuity of our business through this time. At the beginning of the pandemic, we moved quickly to ensure that our inventory of non-isotope supplies were appropriate in case our supply chain was disrupted. In addition, we set in motion our strategy to maintain a continuous and uninterrupted supply of isotope from our suppliers in Russia. Our partners at nuclear facilities in Russia have worked hard to adjust to our needs going above and beyond to support us, which we appreciate immensely. Fortunately, we have not experienced any material supply chain issues to-date. As we think about how COVID-19 is impacting IsoRay's business, it is important to remember the demographics of the patients cancer our customers commonly treat. The majority of the cancers are in prostate. In general, prostate cancer is a relatively slow progressing form of cancer, and does not often present an imminent life threatening emergency for many of our customers' patients. As COVID-19 began to spread, many states implemented new guidelines in an attempt to mitigate spread of the virus and to conserve certain medical supplies, such as PPE. Those guidelines led to the cancellation or postponement of elective and non-emergency surgical procedures including prostate brachytherapy procedures. Consequently, at the very end of March, we saw some procedures begin to be postponed in many markets we serve. This resulted in preliminary revenue for the month of April declining about 20% versus April in 2019. In the recent weeks, as states begin to lift restrictions on non-essential surgeries, we've received an increasing amount of customer feedback that those implants that had been cancelled in March and April were beginning to be rescheduled. Our order growth has been accelerating since the last week of April. We firmly believe that most, if not all, treatments in process prior to the outbreak will take place over the next few months. In the meantime, we continue to tightly manage our expenses and make fluid adjustments to isotope orders to meet potential increased treatment demands as restrictions lift. The COVID-19 pandemic has impacted the sourcing of parts associated with the assembly of our proprietary disposable delivery device Blu Build. This was due to our parts manufacturer temporarily converting their production capacity to making clinical PPE for the battle against the pandemic. We have enough inventory to support our current customers and new customers in the pipeline until our parts manufacturer is back online. We support their decision and as a result now anticipate Blu Build will see a slower than expected release through the remainder of fiscal 2020. With the expectation that Blu Build will continue contributing revenue in the fiscal fourth quarter of 2020 and deem traction in fiscal 2021. Turning to GammaTile and our partners at GT Medical Technologies. GT Medical Technologies launched their full market release of GammaTile therapy in January. In support of this launch, they have extended beyond their current distribution partners to include indirect GT Medical Technologies sales team. For those of you who are not aware of our relationship with GT Medical Technologies, we have a 10-year manufacturing and supply agreement to manufacture GammaTile with Cesium-131 feeds in the tiles to treat both recurrent and primary brain cancers. We remain optimistic about the prospects for GammaTile and the benefit it can offer to many brain cancer patients and are looking forward to how the salesforce expansion proceeds. Revenue from the sales of GT Medical Technologies were again nominal to IsoRay's overall revenue in the fiscal third quarter ended March 31st. On another front, we continue to remain actively engaged with policymakers in Washington D.C. on a number of key items. I am very pleased to report that there is a new development to share with you. Yesterday evening, we were notified that we had received 64 ICD 10 PCS codes for reimbursement in the inpatient DRG setting. These codes allow hospitals to bill Medicare for specific surgical procedures that would benefit from the addition of Cesium-131. You will recall that the ICD 10 PCS codes are important for the growing surgical applications of Cesium-131 in treating hard to treat cancers. Just a few of the codes include lung, head and neck, brain, GYN, pelvic, and many others. These codes will take effect on October 1st, 2020. Another important matter is one you may recall from our fiscal 2019 year in earnings call back in September, I shared with you that CMS had proposed a significant change to the way Medicare currently pays for radiation oncology services in the outpatient setting. The proposed radiation oncology alternative payment method or ROAPM would provide a single bundled payment for a 90-day episode of radiation therapy, including LDR brachytherapy, IMRT, SPRT, proton therapy, and HDR brachytherapy. 17 disease sites, including the prostate are included in this proposal. The common period ended September 16th, and after an initial delay this past fall, the final CMS ruling was rescheduled for release on April 1st, 2020. However, with the onslaught of the pandemic in the U.S. in March, the ROAPM was not released on April 1st, and a date has not been set. We continue to watch for new developments in this matter because we believe that the implementation of this bundle may further level the playing field for brachytherapy over time, given the various radiation treatments available to patients. We have also been working with policymakers to help them understand the importance of Cesium-131 as they turn their attention to ensuring that everyone can safely access the healthcare services necessary to diagnose and treat life threatening diseases beyond COVID-19. We believe that many aspects of brachytherapy using Cesium-131 supports this process. The procedure is a one-time hospital visit reducing the risk of exposure to threatening diseases like COVID-19 and is supported by long term clinical evidence demonstrating positive patient outcomes. This -- done advantage means vulnerable cancer patients do not need to keep returning for multiple in hospital treatments as typically required by other forms of radiation therapy. This also lowers the overall use of personal protective equipment, and even the aggregate cost of the treatment is lower. We look forward to continuing our dialogue with policymakers and their staff to ensure that cancer patients have meaningful and timely access to brachytherapy. Before I turn the call over to Jonathan, I want to take this opportunity to thank all IsoRay employees. Words seem inadequate to describe how proud I am of this incredibly dedicated team. They remained singularly focused on the company mission even as this unprecedented time of uncertainty has impacted all of us seeing this latest demonstration of commitment, and how successfully we adapted during this pandemic, gives me even more confidence in the future success of IsoRay. Now, I will turn the call over to Jonathan to review the results of our fiscal third quarter.
