Thank you, Cody, and thank you, everyone, for joining us on this call. Before we begin, I'd like to remind everyone that this conference call may contain predictions, estimates, and other forward-looking statements regarding the future events and future performance of Quests. Use of words like anticipate, project, estimate, expect, intend, believe, and other similar expressions are intended to identify those forward-looking statements. Such forward-looking statements are based on Quest's current expectations, estimates, projections, beliefs, and assumptions and involve certain significant risks and uncertainties. Actual events or Quest results could differ materially from those discussed in the forward-looking statements as a result of various factors which are discussed in greater detail in Quest filings with the Securities and Exchange Commission. your caution not to place undue reliance on such statements, and to consult the SEC filings for additional risks and uncertainties. Quest forward-looking statements are presented as of the date made, and we disclaim any duty to update such statements unless required to do so by law. In addition, in this call, we may include industry and market data and other statistical information, as well as Quest observations and views about industry conditions and developments. The data and information are based on Quest estimates, independent publications, government publications, and reports by market research firms and other sources. Although Quest believes these sources are reliable and the data and other information are accurate, we caution that Quest has not independently verified the reliability of these sources or the accuracy of the information. Certain non-GAAP financial metrics will be used during the call. These include non-GAAP measures are used by management to make strategic decisions, forecast future results, and evaluate the company's current performance. Management believes the presentation of these non-GAAP financial measures is useful for investors' understanding and assessment of the company's ongoing core operations and prospects for the future. Unless it is otherwise stated, it should be assumed that any financial discussed in this call will be on a non-GAAP basis. Full reconciliations of non-GAAP to GAAP financial measures are included in today's earnings release. And with all that said, I'll now turn the call over to Ray Haas, President and Chief Executive Officer.

Thank you, Dave. And thanks, everyone, for your interest in Quest. We had a strong start to 2022. We grew gross profit dollars by 75% year over year. We grew adjusted EBITDA by 42%. That growth continues to be driven from both organic sources and acquisitions. First quarter results demonstrate the scale and scope of the change that Quest has undergone in the past year. With all this growth, we have also doubled the size of the company in the past 15 months, and we significantly diversified our in-market and client mix. We had a lot of activity in recent quarters, and I want to recognize and thank our team for their hard work and extra hours to continually make our company better and improve our client experiences. Before I go into an update on our progress, I'm going to turn the call over to Lori Latham, our Chief Financial Officer, to review the financials.
