Thanks, Mike. Today and going forward, I will frame my comments in the context of our long-term growth strategy, which includes balancing growth, profitability and liquidity. Let me start with growth. LifeStance continued to deliver solid growth in the fourth quarter with revenue of $190 million, up 61% year-over-year. This included an estimated impact of approximately $1 million to $2 million from an uptick in patient and clinician cancellations in late December caused by the Omicron COVID variant. For the full year, we delivered revenue of $668 million, up 77% year-over-year. Turning to profitability. In the fourth quarter, Center Margin of $54 million increased 39% over the same period last year, driven by strong revenue growth. Full year Center Margin of $202 million grew 69% year-over-year. We generated adjusted EBITDA of $11 million in the fourth quarter or 6% of revenue. For the full year, adjusted EBITDA was $49 million or 7.4% of revenue, slightly down year-over-year, driven by strong clinician and revenue growth, offset by the impact from a shift in labor market dynamics and investments in future growth and scalable infrastructure. Turning to liquidity. LifeStance continues to be supported by a strong balance sheet. We exited the year with cash of $148 million and debt of $157 million. Additionally, the Company ended the year with an undrawn revolver of $20 million. We have no material debt payments due until 2026. In 2021, we generated $9 million of cash from operations, including IPO-related payments and interest payments on long-term debt. Turning to 2022 guidance. We expect another year of strong profitable growth, with revenue of $865 million to $885 million, Center Margin of $240 million to $255 million, and adjusted EBITDA of $63 million to $67 million. For the first quarter, we expect revenue of $195 million to $200 million, Center Margin of $50 million to $54 million, and adjusted EBITDA of $7 million to $10 million. This guidance includes approximately $3 million to $7 million in revenue impact from Omicron. We expect improvements in profitability in the second half of 2022 based on the resolution of the Omicron impact in the first quarter, continued growth in our clinician base and leverage in the second half of the year driven by our strategic decision to moderate de novo center openings as well as scaling in G&A costs. Our planning assumptions include 80 to 90 de novo center openings this year, heavily weighted toward the first half with 70 to 75 openings. M&A spend of $50 million to $70 million and no further COVID-related impacts or changes in the current labor market environment. Additionally, we expect stock-based compensation expense of approximately $190 million in 2022, including approximately $30 million from new 2022 grants. We expect stock-based compensation expense to continue to decrease as the pre-IPO awards vest. To summarize, we remain focused on delivering long-term growth by balancing growth, profitability and liquidity. With that, I'll turn it back to Mike Lester for a few words before going to Q&A.
