Thank you, Jamie, and thanks, everyone, for joining us this afternoon. We're pleased to report that Progyny had a very strong third quarter, both in terms of our financial performance, as well as in the continued execution of our go-to-market activities. Those activities, which include new client acquisition, the retention of existing clients, and the further diversification of our business by expanding into new industries, while also adding new channel partners, have positioned us for another year of strong growth in 2024, with 1.3 million new covered lives sold, as well as a near 100% retention rate for the eighth year in a row. Before I get into the details of the sales season, let me begin with the highlights of our financial performance. We had record quarterly revenue of $281 million, reflecting 37% growth over the prior year period, as well as record adjusted EBITDA, which increased 43% over the third quarter of 2022 to $50 million. This yielded an adjusted EBITDA margin of 17.8%, which was an 80 basis point increase over the prior year period. As we've seen throughout 2023, our results this quarter once again reflect that member engagement remains healthy, demonstrating the importance of companies offering this benefit as members pursue the treatments they need in order to achieve their family building goals. As the prevalence of infertility continues to rise, with more people now needing assistance than ever before, and with millennials routinely citing family building benefits as one of the most relevant factors when deciding where they want to work, we've seen how fertility and family building solutions have increasingly become important to employers as they look to meet their recruitment, satisfaction, and retention goals. Progeny's continued focus on value to our clients and member satisfaction remains the foundation for our ability to lead and grow the market through a combination of a unique plan design, active management of the member experience, and the collaborative relationships we forged with the providers in our proprietary network. We continue to distinguish ourselves as a provider of choice for fertility and family building solutions amongst the world's largest leading brands. We're pleased with this year's sales season, highlighted by adding 1.3 million new lives from over 85 new client commitments, demonstrating the market's continued adoption of family building solutions, and further solidifying our leadership position. Because a small number of these clients both sold and launched in this sales year, we expect over 460 clients and approximately 6.7 million covered lives in 2024. And to put this into perspective, at the time of our IPL just four years ago, we had 87 clients and approximately 1.5 million covered lives, which means we have more than quadrupled our clients and covered lives since 2019. Even with this sustained track record of success, and once our newest clients have all gone live, we still remain at a very early stage of penetrating our market opportunity with just a mid-single-digit share of either the 8,000 companies or the 100 million covered lives in our current addressable market. The clients we've added for 2024 reflect an exceptionally diverse cohort, representing a wide range of industries, including chemicals manufacturing, hospitality, healthcare, energy, transportation, software, and telecommunications, to name just a few. And our book of business now represents approximately 45 different verticals. We continue to see strong momentum through the flywheel effect, where our initial win in an industry lays the groundwork for future success within that vertical as the other brands in that industry look to re-establish parity with the early adopters. A good example of this is the labor market, where we won our first client just a year ago and have had strong second-year success, winning new clients across different types of TAP heartland populations. As just one final anecdote of this dynamic, a year ago, we won our first professional sports team client, and this year, we not only won additional sports teams, we also won our first professional sports league. We also continue to see a broad range in the size of the newest clients, spanning from 1,000 to well over 100,000 lives, which further demonstrates that fertility has become a relevant benefit for any employer, regardless of the size of their operations or the industry in which they operate. This season, we also expanded into our first federal government population, representing approximately 300,000 covered lives. Government plans are a large and attractive new channel for us, particularly as those groups continue to look to enhance their benefits and keep parity to the benefits that their corporate counterparts provide. Given the stringent requirements that any provider must meet in order to be approved to serve the federal market, we believe the flywheel effect has the potential to be even more impactful within government than what we've seen amongst corporate employers, which would make this an accelerator to our long-term growth. At this point, the federal government has defined a fertility benefit more narrowly than what we typically see. To meet these requirements, we modified our usual scope of services and are expecting to see meaningfully lower financial contribution per engaged member from this population in 2024. We are excited about this unique opportunity as there could be increased contribution over time if the coverage is broadened and additional lives are won, similar to what we see with our corporate clients. Setting aside this unique client, the remainder of our newest clients have continued to select robust levels of coverage, offering two or three smart cycles on average, consistent with what we've historically seen. This year, we've also achieved our strongest ever adoption rate for Progyny Rx with 98% of the newest clients taking the pharmacy benefit. This comes on the heels of last year's 97% take rate. We believe our extraordinary success in selling the integrated solution is due to the significant combined cost savings we deliver with integrated medical and RX services, as well as our superior member experience that eliminates the risk of treatment delays, while also guiding the patient through a complex medication protocol. Once all these newest clients launch in combination with the existing clients who added the RX benefit for 2024, we anticipate that approximately 93% of our clients will have the integrated solution. While new sales activity is a critical focus for us and is the largest contributor to our incremental growth each year, retaining existing clients and adding new services are also significant priorities, and we're extremely pleased to have achieved a near 100% retention rate for the eighth straight year in a row, while also expanding the services that we're providing to our clients. We believe our sustained success with retaining an extraordinarily high rate of our clients and lives underscores the demonstrable value that our solution delivers year after year, especially when you consider that our clients include many of the most analytical and data-driven companies in the world. Further evidence of the value inherent in our services, we continue to see existing clients looking to expand their Progyny benefit for 2024, with more than 20% of clients increasing their programs in some way for next year, either by adding more smart cycles, taking Progyny Rx, covering more services such as donor tissue or fertility preservation, or expanding their adoption and surrogacy benefits in recognition of the many different pathways to parenthood. Of course, employers typically have many priorities with respect to their health plan and benefit strategies, and this year was more magnified in this regard. In 2023, we've seen companies evaluating a number of areas from their concerns on overall medical cost trends, which resulted in increasing evaluations of health plans and benefit strategies, as well as the rise of demand around GLP-1 and the overall ongoing macroeconomic uncertainty. Even with these competing factors, we've seen that fertility has remained a significant priority, and we are entering next year with meaningful tailwinds behind us. As in every year, a portion of the prospects in our pipeline end the sales year as of not now due to the competing priorities that I discussed previously. This year is no different, and we have a healthy number of opportunities remaining in our active pipeline that are carrying over into next year. We've gained considerable expertise over the years at effectively managing multi-year sales cycles, and in fact, in each of our previous selling seasons, most of our earliest wins have been conversions of what had once been a not now prospect, and we would expect the same for 2024. Accordingly, we're excited to be entering next year with a very healthy pipeline of advanced opportunities, which of course will be in addition to whatever new pipeline that we build through all of our traditional methods, including the channel partners who play a key role in broadening our reach and improving sales efficiency. Earlier this year, we discussed the new partnerships we forged with a number of leading organizations, Evernorth, Children's Hospital Association, Quantum Health, in addition to our existing relationships with CVS Point Solutions. And though we're only in the early initial stages with our newest partnerships, we're pleased with the progress we've made and feel well-positioned as we look into 2024. To add to this already strong list, we're pleased to announce that we recently signed a partnership with Vistia [Ph] Health, who has selected Progyny to be its preferred vendor for fertility and family building benefits, giving us access to the customers in their portfolio, which includes the clients of one of the largest health plans in Southeastern Pennsylvania. As with our other distribution partner relationships, when a Vistia Health client is looking to add fertility to their benefit coverage, Progyny will be the preferred fertility solution and will collaborate with them during the sales process. We're excited about the potential of this new relationship and view this partnership as enhancing our market presence even further with health plans in 2024, while also demonstrating the strength of our competitive position and our differentiation in the market. With that, let me now turn the call over to Mark to discuss the quarter in more detail and provide our expectations for the balance of the year.
