Thank you, Crissy, and good morning to everyone joining today’s call. The first quarter was a good start to 2018 with consolidated revenue increasing 9.3% leading to a consolidated adjusted EBITDA increase of 11.2% and an adjusted earnings per share increase of 32.9%. These results were achieved with strong volume growth and effective labor management in both segments. Our Inpatient Rehabilitation segment grew same-store discharges 4.8%, the largest same-store increase we've experienced since the first quarter of 2012. The widespread incidence of flu across the country led to capacity issues in many acute care hospitals. This had a positive impact on downstream volumes as we could leverage our efficient referral and approval process to assist the acute care hospitals and the timely discharge of their patients requiring an IRF level of care. The timing of discharges around Easter and Passover also contributed to discharge growth as both fell later in April or the second quarter of 2017. We were very pleased with how our inpatient rehabilitation hospitals managed this increased volume in a disciplined manner and achieved higher labor productivity. Our Home Health segment grew total admissions of 9.9% and grew same-store admissions 7.4%. This growth was achieved against a difficult comp of 13.9% same-store growth in the first quarter of 2017, which included a strong improvement by the former CareSouth locations. In addition, our home health team continues to make improvements to caregiver productivity and efficiency that are allowing us to lower our visits per episode in ways that do not compromise quality or patient satisfaction, as evidenced by our consistently high quality ratings. As a result of this increased revenue and earnings as well as some favorable working capital changes, we also increased adjusted free cash by15.4% to $170.2 million for the first three months of 2018. We’re investing this cash in our strategic initiatives, which included growth opportunities in both of our segments, increased clinical collaboration between our two segments, implementing our rebranding and name change and the development and implementation of post-acute patient navigation tools. In April of this year, we opened a new 34-bed inpatient rehabilitation hospital in Shelby County, Alabama, and we have seven other IRF development projects underway, including hospitals in North Carolina and Idaho, which are new states for us. In our Home Health segment, we recently announced a definitive agreement to acquire Camellia Healthcare. Camellia operates 18 hospice, 14 home health and two private-duty locations across Mississippi, Alabama, Louisiana and Tennessee. We expect to close this transaction prior to June 1. While we continue to maintain an active pipeline of opportunities in our Home Health and Hospice segment and remain open to various opportunities, we plan to focus our attention on integrating the Camellia transaction this year. We are very pleased to report we achieved a new high watermark for clinical collaboration at 33.5% in the first quarter of 2018, up 460 basis points over the first quarter of 2017. We attribute much of this increase to the full deployment of our TeamWorks clinical collaboration best practices across our overlap markets. It's important to note, the objectives of clinical collaboration are not simply to drive higher revenue and admissions growth. The primary objectives of clinical collaboration are to improve the patient experience and outcomes and to reduce the total cost of care across a post-acute episode. While it's still early, we are seeing increasing evidence these objectives are being achieved. The coordination between our IRF and home health teams is resulting in lower discharges to skilled nursing facilities and higher discharges to home and overlap markets. And within our overlap markets, patient satisfaction scores are increasing while hospital readmission rates are decreasing. We also continued implementation of our rebranding and name change, spending $3.6 million during the first quarter of 2018. Our April 2, our inpatient rehabilitation hospitals and home care agencies in Texas, Alabama and Arkansas transitioned to the new brand. Local migrations will continue throughout 2018 and are expected to be completed by the first quarter of 2019. We continue to focus on building the tools necessary to serve as a value-added partner to payers and acute care hospitals for all their post- acute needs. In January of this year, we began a pilot project in our overlap market of Tyler, Texas with CHRISTUS Trinity Mother Frances to manage care navigation for all of their hip fracture patients. Data has shown that for fracture patients, quality rehabilitation can mean the difference between a full recovery and long-term issues. By collaborating to provide proactive care, seamless transitions and constant management through the use of care navigators, we are already positively impacting both care and costs. In the first quarter of 2018, 40 hip fracture patients were part of this collaborative effort, which represented 18 more hip fracture patients than we treated from this acute care hospital in 2017. Of those patients, only one has been readmitted to the acute care hospital. This project also carries over to our work with the Post-Acute Innovation Center, where we're developing advanced analytics and predictive models that don't exist in the marketplace today. We're leveraging existing center solutions for care management workflow and documentation combined with data from our rehabilitation- specific electronic medical record system, Homecare Homebase and the acute care hospitals' Epic system to create a longitudinal patient record to manage patients across the post-acute continuum in Tyler, Texas. This patient record uses algorithms to identify patients for post-acute care navigation, provides a documentation platform for care and coordination includes evidence-based assessments to support complex case management and includes care plans that can be easily communicated to primary care physicians and other service providers and caregivers. In addition to this active project in Texas, the Post-Acute Innovation Center is working to develop a 90-day post-acute readmission prediction model to identify patients at risk for readmission across all post-acute settings. As we begin developing post-acute networks in various markets, the center is also working to better define what it means to be an effective and efficient post-acute provider and developing a post-acute determination support tool. Once we're ready to expand our post-acute management abilities to other markets, these tools will help us drive outcomes and costs by placing patients in the right post-acute setting with the right post-acute provider. Before moving to guidance, I want to comment on the market consolidation decision we made in our Texas region. In April, we announced our plans to create a more efficient operating structure in the Fort Worth, Texas market by consolidating our three inpatient rehabilitation hospitals into two hospitals. Two of our hospitals were within nine miles of each other, with one of those being an owned facility with all semi- private beds in Downtown Fort Worth. We have stopped admitting patients to this hospital and we'll officially close it in May. The remaining two hospitals known as City View and Mid-Cities have excess capacity that is sufficient to absorb the additional census from the closed Downtown Fort Worth hospital in the near term. This belief in our ability to absorb the volume into two locations is validated by the fact that about 600 employees across all three hospitals less than 10 were displaced as a result of this market consolidation. We currently plan to sell the building in Downtown Fort Worth and use the proceeds to fund a capacity expansion of approximately 30 beds at the City View Hospital. We believe the consolidation of operations and construction of new private beds will contribute to improved financial performance and improved patient satisfaction in the market. Now moving to guidance. As a result of our strong start to the year, we are raising our full year guidance ranges as follows. We're increasing net operating revenues from a range of $4.08 billion to $4.19 billion to a range of $4.11 billion to $4.21 billion. We’re increasing the bottom and top ends of our adjusted EBITDA by $15 million to a range of $845 million to $865 million, and we're increasing the bottom and top ends of our adjusted earnings per share by $0.05 per share to a range of $3.30 to $3.45 per share. These increased guidance ranges are inclusive of our planned acquisition of Camellia prior to June 1. With that, I'll turn it over to Doug.
