Thanks, Dave. We continued to line our teams around two growth priorities, net clinician ads and clinician productivity. We grew by 227 net clinician ads in the fourth quarter and 1014 for the full year, bringing our total clinicians to 6645, an increase of 18% year over year. Importantly, our growth in Q4 remains 100% organic for the third consecutive quarter. Our clinician value proposition remains strong and we are proud of our clinician recruiting and operations team's great work in delivering clinician growth in 2023. Turning to clinician productivity, for 2023 on a visits per average clinician basis, we saw productivity increase by 2%, driven by many of the operational actions we took throughout the year. As a reminder, productivity is a function of two components, clinician capacity or the time clinicians give us and utilization our ability to fill clinician time with patients. In 2023, we put our focus towards utilization, delivering on our core commitment to our clinicians to fill their schedules by driving operational discipline throughout the patient funnel. At the top of the funnel, we made enhancements to our primary care referral team, organic search traffic, internal clinician referrals and enterprise referral partnerships. These actions delivered improvements in attracting new patients above the growth of our clinician base demonstrated by our growing waitlist for services. I will note that our cost per new patient acquisition continued to decline year over year and we spend a de minimis amount on paid advertising as part of our top of funnel strategy. Second, at the middle of the funnel in terms of converting patients to scheduled appointments, we continued to leverage our digital capabilities to improve patient matching via our Online Booking experience, OB which we rolled out nationwide. Additionally, we enhanced the patient experience with better online clinician profiles, reduced scheduling complexity and enhancements to our phone intake processes, which is a key area for 2024. Finally, at the bottom of the funnel in terms of scheduled appointments converting to completed visits, our cancellation and no-show rates have now stabilized in the 9% to 10% range, which is a significant improvement from the previous 15% level when we set this as the focus area for improvement. As we head into 2024, we are shifting our attention to the other side of the productivity equation, clinician capacity. We have early initiatives in place to grow overall clinician capacity with a goal to reward and incentivize those clinicians offering full time hours. For example, we are using tiered benefits to provide incentives such as medical coverage and 401k match to full time clinicians. Additionally, our recruiting team is focused on attracting clinicians who desire full time employment, and finally, we offer equity ownership through our long term incentive program to attract and retain our highest contributing clinicians. In addition to improving clinician productivity we made notable strides in other areas during the past year. First, in terms of leadership, we reorganized and upgraded our practice operations senior leadership team. We made significant changes streamlining the number of senior leaders, promoting top performers, and bringing in new external talent with the appropriate skill set to guide an organization of LifeStance's current and future scale. Second, in terms of KPIs, we reoriented our operations teams around a metrics driven approach to managing the business and instituted a new reporting suite of KPIs to bring focus, prioritization and data driven decision making to the organization while continuing to emphasize the patient and clinician experience. Third, in terms of culture, we recentered the company around supporting local operations and clinician needs while emphasizing belonging and connection. For example, we prioritized increased teammate engagement via social gatherings, recognition and appreciation and participation in community volunteer events. Fourth, in terms of cost efficiency, we completed our real estate optimization project. In total, we consolidated 82 centers in 2023 with little to no disruption to our patients and clinicians. We opened 35 de novo centers and will continue to intentionally moderate our pace of openings with an expectation of no more than 20 de novos in 2024. Finally, we made tangible progress in standardizing and streamlining the business including moving to a single EHR phone system, KPI suite, and online booking tool, as well as creating a single operating model for our regional support teams. Looking ahead to 2024, there is no shortage of opportunities for improvement with many new initiatives unlocked by the work done in 2023. Delivering an amazing patient and clinician experience remains a top priority for us. I'd like to take a moment to discuss three tangible examples of how we are going to do this while also generating operating leverage. First, we are continuing to invest in the front office of our centers, focusing our resources on those areas of support that most directly impact the experience of our patients and clinicians. We are increasing our center staffing levels over 25% by year-end and redesigning our processes to better support our patients, clinicians, and administrative support teams. Second, we are making improvements for new patients booking by the phone. We are rolling out a new phone booking tool that leverages the matching capabilities of OB, our online booking tool. This will further enhance the patient-matching experience while significantly reducing complexity and increasing the speed of scheduling over the phone for our intake team. Third, we are piloting a new digital patient check-in tool that will allow us to collect and verify patient information upfront as well as allow patients to pay their balances more easily. This will reduce stress for our patients and manual complexity for our operations and billing teams. We are doing all three of these things while also meeting our commitments to margin expansion in 2024, demonstrating that delivering improved patient and clinician experiences while also delivering improved operating leverage can be accomplished simultaneously. I'm proud of what our teams have accomplished over the past year and am equally excited about the opportunities in front of us in 2024 and beyond. I'm also particularly proud of the strength of the leadership bench that we have built, which delivered on our commitments for the full year 2023 and will be instrumental in leading the long-term profitable growth of the business. With that, I'll turn it back to Ken for his closing remarks.
