Thanks, Mark, and good morning, everyone. I'll add some detail to our fourth quarter results and then speak to the notable headwinds and tailwinds we've contemplated as we look at 2021. Lastly, I'll touch on our financial position and the capital available to us for future allocation. Turning to the quarter. At the top line, our net revenue declined by $42 million or just over 9% year-over-year and by $44 million compared to the third quarter. I'll point out that we recorded only a very small amount of revenue from the provider relief fund established by the cares Act during the quarter. Same unit volumes declined 6.6% year-over-year, which compares to a 4.3% year-over-year decline in the third quarter. We provided a brief table in our press release with some volume detail that allowed a couple of points for color. First, during the fourth quarter, volume declines were more pronounced in November and December than they were in October, which for many of our service lines appears to coincide with the surge in COVID cases across the country, and the likely negative impact that had on patient volumes and our office-based services, as well as on selected pediatric services we provide them a hospital. Second, our NICU days were down by a greater amount and total worse at the hospitals, where we provide NICU coverage. This reflects modest year-over-year declines in both the rate of admission in the NICU and the average length of the stay. And third, in our office-based practices pediatric cardiology volumes were the most impacted during the quarter, while MFM volumes were down only slightly compared to last year. On the pricing side, the most significant factor in the fourth quarter was payer mix, which shifted roughly 200 basis points toward government payers compared to last year and impacted our top line negatively by roughly $10 million. On the expense side, I want to share a few thoughts that can demonstrate both the variability in our cost structure, in the act of steps we've taken to enhance our efficiency. First, our practice level salary, wage and benefit expense was down by $15.3 million for just over 5% year-over-year. This reduction mostly reflects the variability in our practice-based compensation structures, primarily bonus expense. And second, our G&A expense was down $4.5 million year-over-year. Despite the fact that we incurred approximately $5 million in transitional service expense, primarily related to the sale of American anesthesiology earlier in 2020. The reimbursement for those expenses is reflected in our investment and other income line items. So there is a minimal impact to our adjusted EBITDA, but they do inflate our recorded G&A expense. I'll also make a similar point looking at our results, on a sequential basis compared to the third quarter of 2020. Overall, our revenue declined by roughly $44 million, while adjusted EBITDA declined by about $14 million. Keep in mind that a significant component of these declines was the cares Act funds we recorded in the third quarter, which contributed $14 million in revenue and $8 million in adjusted EBITDA. And which did not recur in any meaningful way in the fourth quarter. Now, turning to 2021, as Mark mentioned, we saw some improvement in trend in January versus the fourth quarter of 2020, our same unit revenue declined by 5% year-over-year with same unit volumes down by roughly 6%, offset a bit by net pricing growth. Keep in mind that January 2021 had two less office days than in 2020, which reduced our same unit volume by just over 2 percentage points. Additionally, our payer mix by volume was about 100 basis points unfavorable year-over-year versus 200 basis points in the fourth quarter. So overall, while same unit revenue continued to show a decline in January, it was less significant than what we’ve reported for the fourth quarter of 2020. Lastly, our NICU days declined by 3.2% versus a 6.3% year-over-year decline in the fourth quarter. Looking at 2021 as a whole, I think that Mark gave a lot of details on the tailwinds we're contemplating, including our organic growth plans, M&A expectations and patient access and enhancements across our office-based practices and then telehealth. I want to add to that some color on our expectations for G&A. As you'll see in our reported results, our G&A for the year was $249 million or 14.4% of revenue. This is a somewhat distorted figure since it includes roughly $18 million in PSA related expenses we incurred. In 2021, we do anticipate the dollar decline in G&A as compared to 2020, even though, we will still be incurring additional PSA expenses, and based on additional efficiencies, we believe are available to us. We view our future state G&A profile as moving below 13% of revenue. So the G&A reductions we expect to achieve in 2021 represent not only a potential tailwind for this year, but an additional potential tailwind beyond 2021, as we move toward that future state. And possibly further based on the pace of the revenue growth over the coming several years. In terms of specific headwinds, our 2020 adjusted EBITDA includes a $14 million benefit from the cares Act we received. Why we may receive additional funds in 2021, we're conservatively not anticipating any material contributions to adjusted EBITDA this year. Secondly, we've contemplated a modest negative impact to pricing based on a number of fee schedule and coding updates finalized by CMS through last year. And finally, as I've highlighted already there were likely be some timing lag between the one down of our TSA agreements and our ability to reduce the expenses we're incurring under those agreements within our G&A line item. There is one last item for those of you keeping the models. I do with the highlights the seasonality of our operating results, particularly given the unusual nature of last year's pandemic impact, but also with an emphasis on the quarterly results from continuing operations for 2020 that were provided last fall. First, as most of you know, Mednax normally has a relatively low contribution to full year adjusted EBITDA in the first quarter, due to the restart payroll taxes, 401(k) contributions and other factors. Additionally, since the last year's first quarter reflects only a partial impact from COVID, we expect that adjusted EBITDA for the first quarter of 2021 will be lower than our adjusted EBITDA in the first quarter of 2020, which was $33.1 million. Lastly, I'll touch on our financial position and cash flow profile. We should be far more straightforward now that all of the significant transaction activity of 2020 is behind us. On the balance sheet side, we completed the sale of Mednax Radiology Solutions in December for roughly $865 million in net proceeds, and in early January of this year, we redeemed our $750 million and 5.25% of senior notes for $764 million in cash. Based on our cash on hand at the end of December and that redemption at the end of January, we had $1 billion in debt, representing our 2027 notes and approximately $370 million of cash, for net debt of just over $600 million. And our go-forward interest expense should be approximately $16 million per quarter, assuming no material borrowings on our revolver. In terms of cash flow, our historical experience has been that we convert somewhere in the range of 60% to two-thirds of our adjusted EBITDA to GAAP operating cash flow. And our annual recurring capital expenditures should be under $25 million this year. This expected free cash flow in 2021, combined with our existing cash on hand and borrowing capacity under revolver, provides us with significant available capital for both contemplated and uncontemplated acquisitions, as well as any shareholder friendly uses we may consider in the future. With that, I will now turn the call back over to Mark.
