Well, thanks, Lynn, and good afternoon, everyone. Thank you for joining us to review ICF's first quarter results and discuss our outlook for 2023. Our strong first quarter results reflected ICF's expanded capabilities in the growth markets we have identified and have invested in, namely IT modernization, public health, disaster management, utility consulting, and climate, environment and infrastructure services. These areas have priority spending for our clients and in 2022 accounted for approximately 75% of revenue. Thanks to our deep domain expertise and increased scale, we expect these areas to continue to grow as a percentage of ICF's revenue in 2023 and beyond. In terms of takeaways from our performance in the quarter: First, we reported over 15% growth in service revenue and total revenue increased close to 17%, of which organic growth was north of 8%. Second, we achieved significant year-on-year margin expansion in the first quarter, primarily resulting from increased scale, higher utilization levels and reduced facility costs. This margin expansion is in line with our guidance of 15% adjusted EBITDA to service revenue margin for the full year. Third, we made the decision to exit a small noncore commercial U.K. events service line that was not contributing to profitability. While immaterial from a revenue perspective, it is indicative of our strategy to focus our investment dollars and human capital in areas that are or have the potential to drive growth and are synergistic with the rest of our service offerings. Fourth, this was another quarter of strong contract awards for ICF, up over 13% year-on-year and resulting in a trailing 12-month book-to-bill ratio of 1.3. Also, our business development pipeline increased 16% sequentially after more than $400 million in contract wins, which speaks to the high level of bid and proposal activity we are experiencing as well as the increased value of the contracts we're bidding on. Taken together, these accomplishments represented a strong start to the year and underscore our confidence in ICF's performance in 2023 and beyond. Looking across our client categories, there are several highlights worth noting. Revenues from federal government clients increased over 22%, reflecting a combination of high single-digit organic growth and the contribution from the SemanticBits acquisition, which we closed in July of last year. Our IT modernization and public health markets were key drivers of first quarter growth in this client category, reflecting strong spending trends amongst our civilian agency clients. Both areas have seen robust funding and bipartisan support. A recent Bloomberg analysis cited IT contract spending at federal agencies is forecasted to be a record of $78 billion for 2023, with about 40% of that spend taking place in the fourth quarter. Additionally, the analysis noted that civilian agency procurement is continuing a pattern of steady annual growth not seen since at least 2017. Federal agencies are prioritizing customer experience in digital services along with data access and use, which are directly in our sweet spots. The integration of SemanticBits is complete. In the first quarter, we continued to win additional business from existing clients. Additionally, we are working together on many potential revenue synergies, primarily at the Centers for Medicare and Medicaid Services, an agency that SemanticBits has served for many years. As mentioned previously, this was a strong quarter for our public health work. In the first quarter, we continued to execute on a number of contracts supporting federal agency efforts to address mental health, substance abuse, and infectious disease and global health security. We also worked on issues related to health equity, social determinants of health and the future of the public health system. Adjacent to this work was the first quarter ramp-up of a new contract for the Administration for Children and Families, Office of Refugee Resettlement to assist arriving Afghan refugees in getting access to immigration and legal services. Additionally, we continue to experience demand from federal clients for ICF services with respect to the Infrastructure [Investment] and Jobs Act. Under existing federal agency contracts, we've been tasked with more than 45 million in projects to support IIJA activities. ICF is providing a range of support to agencies, including digital modernization, technical assistance and communications and management support for IIJA programs. Also, ICF has seen considerable interest from states and other prospective IIJA funding recipients for a range of environmental support services, including planning and analytical services. Our pipeline of opportunities containing IIJA and Inflation Reduction Act or IRA-related work continues to grow and is currently at approximately $250 million, up from $150 million at the end of 2022. This includes a modest amount of work related to the IRA where we expect to see awards to support Federal agencies' responsibilities under the Act late in the second half of this year. In the first quarter, our revenues from state and local government clients increased 13.3% year-on-year. Its 2 key business areas: disaster management and environment and infrastructure consulting that executed effectively on existing contracts and continued to win new work. In particular, we noted in our release, the award of a new contract with a value of $25.9 million with a U.S. territory to support implementation of its new energy program that will provide eligible households with renewable energy installations in case of an extended power outage. Also, we continue to win smaller strategic resilience advisory work in new jurisdictions and with new clients in current geographies. We currently are doing mitigation advisory work for 30-plus clients across 17 states and 3 territories, which enables us to build relationships in key markets and to position for downstream implementation and new recovery work. There are significant synergies between our disaster recovery and mitigation work and the resilience and energy-related work we do for state and local and commercial clients. In Q1, we continue to see these synergies pay off with good-sized wins with critical infrastructure clients in Oregon and California. This is a good segue to our commercial energy business, where revenues increased almost 19% in the quarter, with each component of this business posting strong double-digit growth. Our commercial utility program revenue growth was driven by 2 large energy efficiency projects, the addition of several new marquee clients, as well as the expansion of the projects for existing utility clients. We saw particular strength coming from our innovative offerings related to electrification and grid modernization, behavioral efficiency programs, and dynamic pricing. In Energy Advisory, we experienced strong demand for our services in the areas of decarbonizing energy markets, in particular, demand from renewable energy developers whose business is supported by the IIJA and IRA. We recently introduced EnergyInsite, ICF's technology-enabled service helping developers identify and analyze renewable project locations, and a new power price forecasting subscription service, and both have been met with favorable client response. Our environment and planning work grew substantially in the first quarter, led by energy sector-related projects as well as the Blanton acquisition and the general ramping up of environmental projects. Growth in energy projects was strong both for developers seeking to permit new onshore and offshore projects and for utilities seeking environmental permits for large infrastructure, reliability and resilience projects, such as the undergrounding of power lines. To sum up, the first quarter was a period of excellent execution for ICF in which we made significant progress in tiers that support our full year 2023 guidance as well as our longer-term financial targets. Now I'll turn the call over to our CFO, Barry Broadus, for a financial review. Barry?
