Thank you, Matt, and good morning, everyone. I hope that all of you and families are safe and healthy. Before I make some introductory comments on the state of senior housing, and on capital allocation environment, I want to welcome John Burkart, our Chief Operating Officer to this call. John joined Welltower last week after illustrious 25 year career to Essex. We believe he will make a tremendous long-term impact on our platform. Following my remarks, as usual, Tim will walk you through our operating and financial results. We're cautiously optimistic on the senior housing business as occupancy is starting to build and we're encouraged by nearly 200 basis points of spot to spot occupancy growth in second quarter, which clearly exceeded our expectations. Momentum in US continued to be strong, with lead generation returning to pre COVID levels, resulting in a 280 basis points occupancy gain in the quarter and the UK remain resilient despite the rise in the Delta variant cases being driven by the younger cohorts. Though, we are monitoring the situation closely we have seen very little impact to the portfolio so far as UK case counts more broadly appear to be decreasing rapidly after recent spike. While Canada was a drag on occupancy, we are witnessing some green shoots following a material decline in COVID cases. In fact, tours almost doubled in June from April and May in Canada, as provinces have removed moving restrictions and are now permitting in person tours. For our overall portfolio, June was particularly impressive month with move in exceeding 2019 level for the first time since the beginning of pandemic. I'm also encouraged that our operators were able to achieve these occupancy gains, while holding rate reflecting the need based nature of our asset class, and strong value proposition of this business. Year-over-year same store revPAR is up 3.2% across our assisted living properties, 2.8% across our independent living properties, and 5.3% across our wellness housing communities. The strength in same store revPAR was primarily driven by our highest end luxury products in primary coastal markets. Having said that, I'll caution you that there is still significant uncertainty and many unknowns related to the path of COVID. And it is too early to signal an all clear. However, we're very pleased with the progress that we're making towards achieving the substantial embedded NOI growth in our Show portfolio. Last quarter, we provided details of nearly $0.5 billion of NOI upside, which assumes a return to fourth quarter 2019 occupancy and margin levels. We're pleased to report that we not only achieved $71 million towards this total goal in one quarter, but also added another $29 million potential upside through the second quarter of acquisition and development deliveries. Going forward, we'll still have another $430 million to NOI upside in that business. Again, this only assumes a return to pre COVID occupancy with potential upside from high rates and return to frictional vacancy, which is mid to high single digits. Turning to capital allocation, last fall when we have made a significant pivot from defense to offense, we made it explicit bet that consumers will return to this new trend business with 400 basis points of occupancy ramp in US from March trough with healthy rates, it appears that we're on the right side of that bet. Over the past three quarters we have deployed $4 billion of capital at extremely attractive pricing during a time when others were fearful. But we remain paranoid optimists and our humility and lack of complacency are pushing us to test our hypotheses, and underwrite everything we look at with conservatism. And you can rest assured that we look at pretty much everything in our space. Therefore, we are only willing to pay a price per unit that does not require everything to go right for our owners to make a reasonable return. The second quarter was one of the best quarters from a capital deployment perspective, having closed approximately $1.4 billion of growth investments. Q3 will likely top Q2, and we anticipate that it will be another record quarter of investment activity for the company. We started Q3 with a bang. And so far in July, we have already closed $230 million of gross investment and expect our previously disclosed Holiday transaction to close in third quarter as well. While it is fun to talk about large transactions like Holiday, which I'll get to in a minute, I want to point out that our core strategy and strength is granular transaction with a diverse group of operating partners, and is supported by our data analytics platform. Our COVID class, which I define as anything we bought is turning to offense in Q4 of last year, now exceeds $4 billion of gross investment activity, including Holiday, across 37 transactions with 24 unique partners. In the US, that would on average be $16.6 million per community, or $161,000 per unit, which we believe represents a significant discount to replacement costs. The pipeline remained very strong with many owners and operators eager to join our operator and data platform. Let me give you some examples. First, I'm very pleased to announce that we'll expand our relationship with John Moore and his team at Atria while Lilly and her team and Holiday will join our platform. We're buying 80 nearly identical Holiday Independent Living assets at more approachable end of senior living spectrum with an addition of six more combination AIL assets for a total consideration of $1.58 billion or $152,000 per unit. Our base remains compelling even after our anticipated investment of $1.5 million to $2 million of CapEx by community to bring them to tomorrow standard. While the lease up of this portfolio from the compelling basis through -- a double digit unlevered IRR, we believe there are few opportunities to enhance our return. Number one, our underwritten rent growth is 2.5% per year, despite a heavy investment in the portfolio that will improve asset quality and marketability. Our 2026 underwritten rent remains $700 to $800 below feasibility rent to make development pencil. Two, we have a significant expansion opportunity in 10 plus assets which we expect will generate a double digit return on invested capital; three, the optimization of six AIL buildings under Atria platform and four, there are at least five higher and better use opportunities and a couple of them are so significant that they may generate enough proceeds to pay for a significant portion of the CapEx investment for the whole portfolio. If we are successful in this effort, we will have a completely renovated portfolio at roughly out going in basis, which will enhance our IRR materially. Moving forward from Holiday, I like to make the operative specific comments on this call. First, while we continue to be encouraged by Jack Callison's at Sunrise. Jack is refocusing the organization as a premier Senior Living brand in North America. We are excited about this focus growth strategy and brought Sunrise in to run a recently acquired community in the Philadelphia metro area. This is our first acquisition initiative with Sunrise in several years, and believes we'll have many opportunities to grow together. In the UK Sunrise platform and portfolio will be acquired by Signature and Care UK Signature is an existing Welltower operating partner which runs our high fin communities in the UK. We're tremendously excited to welcome Care UK to our platform, which is one of the most well respected and largest Senior Living operators in the UK, with the addition of 81 on the value end and Care UK on the higher end along with our existing operating partners, the barbell approach to portfolio construction that we have taken in the US which is all an -- which we always aspired to be in the UK is beginning to take shape. We're very excited about Care UK technology and management platform. We're also thrilled to welcome Pathway Living to Welltower's operating platform, which we believe opens another avenue for growth for us. Next, I'm excited to announce our expanded partnership with Oakmont Management Group, which is one of our strongest and best operating partners. This expanded partnership with Courtney and her team is expected to result in a nearly doubling of our time portfolio together in California. We're also embarking on a long-term exclusive development program together to meaningfully expand our relationship in the next decade. Fun fact, Oakmont is our first operator in our portfolio to return to the 90% occupancy mark post COVID, a reflection of Oakmont's operating acumen and market strength. Finally, I'm excited to announce our new partnership with Chris Smith and his team at Aspect Health. We recap Aspect's existing MOB portfolio in Connecticut and at New York and entered into a long term Development Partnership with Chris. We believe a combination of our data and operating capabilities with Aspect's relationships, and development talent will create significant opportunities for growth for both companies. We're already on our first development together, which will be a 60,000 square feet outpatient medical building located at a very attractive market in the New York metropolitan area. The property will be master leased to a leading health system for 20 years and is expected to start construction early next year. Speaking of growth opportunities, I'm pleased to announce our continued growth with the Bremner organization. In the next, in the second quarter, our partnership closed on the first building of a large development near Norman, Oklahoma with Normal Retail Health System. The total development cost for phase one of this multi phase development is expected to be in excess of $100 million, consisting of 181,000 rentable square feet, a classy outpatient medical facilities. Our significant MOB development platform pipeline, which is 100% leased, is now in excess of 1 million square feet and will create significant value for our shareholders in a very tight acquisition market. All of these operating and development partnerships make us the foundation for our core belief that centralized capital allocation and decentralized execution releases entrepreneurial energy while keeping costs and politics at bay. We are very proud that we have formed 50 new operators and develop relationships since the beginning of pandemic. And we have a handful more in the works. The implication of our rapidly growing operator and development platform are vast, including a network effect, whereby addition of more operators creates exponentially recent data set, and thus stronger and attractive an analytics platform. This dramatically enhances the informational advantage we're already positive through our best-in-class with analytics platform, which forms the basis of our capital allocation decision. Needless to say, these relationships create foundation for significant capital deployment opportunities, as each one of them are attracted world vehicle on their own right. This Lollapalooza effect of intertwining operating and data platform has created a wide and increasingly deeper mode for Welltower. As Tim will speak to you in a moment, we're very pleased to with our progress to further strengthen our balance sheet and liquidity profile. More specifically, our sequential adjusted EBITDA growth of roughly $50 million indicates that we're on our way to deleverage organically as senior housing properties unfold. Overall, we're very happy with our execution so far in the year to create cost share value for our shareholders. We're cautiously optimistic about the fundamental environment, and excited about our opportunities to acquire and develop talent, create new relationships, and attract quality partners, which will result outside internal and external growth for years to come. After retooling our assets and portfolio operators, and building a formidable predictive analytics platform and talent base, and growing with conviction following two negative cycles superimposed on each other, resulting from oversupply and COVID, I'm happy to say that we're emerging as a partner of choice, an employer of choice and an investor of choice on the other side of this pandemic. With that, I'll pass it over to Tim. Tim?
