Thank you, Jamie. Thanks, everyone, for joining us this afternoon. 2023 was another exceptional year for Progyny, a year in which we achieved record levels of revenue, which grew 38%, profitability with a 17.2%, adjusted EBITDA margin and operating cash flow generating nearly $190 million or more than twice what we delivered in 2022. As important as those financial measures of success are, we're equally pleased with what we've achieved operationally. I'll touch on just a few of these highlights. Driven by our remarkable levels of member and client satisfaction, we once again maintained our near 100% retention across our client base, while also concluding a selling season that yielded the largest number of new covered lives in our history. We deepened our already highly collaborative relationships with clinical providers while also extending the reach of our vast network through the addition of reproductive urologists with the Progyny network now reaching more than 1,000 of the highest quality REIs and RUs in the country. And we expanded our solution to address both menopause and the treatment of male infertility. Aided by the quality and reach of that network and the ways in which we collaborate with them, we continue to achieve, for the eight straight year, the industry-leading clinical outcomes in fertility care. And in 2023, we helped the largest number of members in our history realize their family building dreams through healthier and faster journeys, while controlling costs. In fact, since launching our solution in 2016, we've cumulatively helped hundreds of thousands of people successfully navigate what would otherwise have been a complex, stressful and overwhelming course of treatment. And we've done so while routinely achieving NPS scores in the 80s, an exceptional achievement for any industry, let alone healthcare. As a mission-driven company, where everything we do is about empowering people to successfully meet the milestones in their lives through evidence-based solutions, we're perhaps proudest of our sustained clinical success, because we understand how those outcomes aren't just numbers on a page, but tangible life changing results for people every day. To put it simply, there are tens of thousands of babies in the world today who were born after their parents turned to Progyny for support typically after having been unable to conceive on their own or unable to carry a child to term. It's helpful to remind ourselves of these successes, particularly when the news cycles over the past week have focused on a potential barrier in the state of Alabama with respect to access to care. And we're fully committed to ensuring that access to IVF will continue for all of those in need, including our members, regardless of where they live. Just as we saw two years ago following the Dobbs decision, a number of state legislatures and governors including Alabama's have indicated their intent to take action to ensure the continued availability of these services. And while this is encouraging, it isn't surprising to us given how life-affirming these services are to the millions of individuals who've already used it successfully and the reality that an even greater number of people will need it to turn to it in the future. It's likely many of these legislators know someone personally who has needed access to fertility care in order for some people to realize their family building dreams. As we've said previously, one of the macro trends driving the demand for care is the increasing prevalence of infertility, which has gone from one in eight just a handful of years ago to one in five today according to the CDC. You've seen that reflected in the strong member engagement metrics that we've reported to you in 2023. Continuing the pattern that we've seen all year, utilization in the fourth quarter was up versus the comparable period in 2022. And although our Q4 guidance reflected the typical decline in member activity due to the holidays and clinic closures for routine cleaning and maintenance, the actual decline in December was slightly more than what we had anticipated, which is why revenue ended up closer to the midpoint of our Q4 range. As 2024 began, utilization returned to levels that are more consistent with what we would expect to see early in the year, demonstrating that the benefit is being used by both new and existing members. And while overall utilization levels are in-line with last year, as at this point in the quarter, there was a brief shift in treatment mix at the start of the year, which we estimate resulted in an approximately $15 million headwind on revenue in the quarter from what we normally would expect and which we've reflected in our guidance for the first quarter. While this phenomenon doesn't happen often and has only occurred once since we've been a public company back in the summer of 2021, when it has happened, it's always been short lasting and has reverted thereafter to the more typical distribution of treatments. To that end, we've already seen treatment mix return to more customary levels over the second half of the quarter with February activity closest to normal than in January and the visibility we have into March that indicates it's trending to typical expected distribution, giving us confidence that this aberration was like all previous ones short lived and now behind us. While Mark, will walk you through our guidance for the first quarter, given what we are seeing now, we're expecting that the activity in Q2 and over the balance of the year will be much more consistent with the historical trajectory, which is reflected in our full-year guidance. That trajectory reflects a continuation of the macro trends that have been fueling our growth, namely the need for fertility benefits is higher than ever with an increasing number of people affected by infertility as a medical condition. People are continuing to wait until later in life to start their families and in doing so are more likely to meet fertility care and family building is still a priority. In fact, these macro factors continue to create a number of tailwinds that we expect will continue to grow our longer term success. First, demand for fertility benefits is stronger than ever, particularly among the millennials who are in the prime of their family building years. Second, family building and women's health benefits have never been more relevant or more timely with employers, particularly as they look to modernize the coverage they're providing in order to better support their employees' needs. Employers increasingly realize that in doing so, they're not only enhancing the efficiency of their recruitment and retention efforts, they're also meaningfully improving workforce productivity. Third, employers are continuing to demonstrate their commitment to family building and women's health services and they're doing this by adding coverage when they don't already have it or by expanding their coverage to provide even greater access to care, by broadening the scope to include other pathways such as adoption and surrogacy and by including other services into their programs such as preconception, parenting and menopause. And lastly, by leveraging our proven strengths in patient education and support, evidence-based care pathways, network management and outcomes measurement, Progyny continues to successfully differentiate itself in the market by raising the bar for what employers should expect from their benefit providers. This experience ideally positions us for success as we enter 2024 with a more comprehensive set of services. 2024 selling season is in its very earliest stage. And while it's too soon to offer any quantitative commentary, the early activity that we're seeing thus far is very positive. Our active pipeline, which at this early point in the season consists primarily of the opportunities that were carried over from last year, is the largest it has ever been at this time of year. And the pipeline will expand as additional opportunities are created through our channel partner relationships, our own demand generation activities, participation at key conferences, introductions facilitated by the benefit consultants, RFPs and all other activity. We've also had a number of early wins, including well-known brands in apparel, healthcare and media, just to highlight a few. In short, we've entered 2024 with considerable momentum, which comes on the heels of our last three selling seasons, which were the most productive in our history. And despite that rapid growth over such a short period of time, we continue to be at a very early stage of penetrating our market opportunities, just a mid-single digit percent of either our targeted clients or covered lives. Though we've expanded our addressable market in recent years by first adding labor and then adding federal government populations, we have opportunities to expand our TAM even further with other types of employers. Because of our proven history of delivering real and sustained value in family building services, we enjoy a sizable advantage as our clients will often proactively share with us the gaps they're looking to address across other areas of healthcare, particularly with respect to patient access, member experience and cost efficiency. In fact, because the Progyny member experience is so unique and what we deliver is so special, we've had clients tell us about the letdown once a member has concluded their Progyny journey and has to return to the health plan or some other solution for further support. That's why Progyny is so uniquely positioned to expand our already industry-leading platform into other areas that further support life's other key milestones. We've made investments in our product organization and we'll continue to expand that team in 2024 to enable us to quickly add new features to existing services or expand into new areas in ways that make sense for us and our clients. These include areas like preconception support where we can help address conditions that often negatively impact the ability to conceive such as PCOS or endometriosis or maternity, where we can help expectant mothers navigate the pregnancy journey, postpartum as the new parents look for support as they adjust to the new addition to their family and think about their eventual return to the workforce. These services are being included in our 2024 selling season for both new clients as well as upsell activity amongst existing clients for contribution beginning in 2025. And in conclusion, the early selling season activity gives us confidence that the macro trends driving the high demand for family building benefits combined with our position as the leader in the space position us well to sustain our growth trajectory. And given the caliber of the companies that we're both partnering with and seeing in our active pipeline, it's become even more evident that Progyny is the provider of choice for fertility solutions amongst the best known and most successful companies in the world. Let me now turn the call over to Mark, to walk you through the results in more detail. Mark?
