Thank you, Mike. And good morning, everyone. And thank you for joining us on what is our first earnings call as one organization. By now hopefully you have seen our press release sharing our results for the third quarter. On behalf of the entire leadership team and the over 6,000 team members of Option Care Health, I'm thrilled to share an update on our efforts to integrate and set the standard for alternate site infusion therapy. Overall, I am very pleased with the progress we have made. And I'm very proud of how our two businesses have come together in a short timeframe to begin building a truly extraordinary organization as one team with a unified purpose. I want to spend a few minutes reviewing the high-level financial results before revisiting the merits of the merger and providing an update on the progress over the past 90 days. Mike will walk you through the financial results for the quarter in a bit more detail. But I do want to reiterate that as a result of the merger on August 6, our performance as released this morning represents a full quarter of Option Care and incorporates legacy BioScrip results from the date of the merger through the end of the quarter. So the results as reported do not represent full quarter's results as a merged enterprise. While we are not providing pro forma results for the quarter, we'll try to frame the results on a comparable full quarter basis where possible. Net revenue for the quarter was $615.9 million representing a 24.7% growth over prior year on a reported basis. On a comparable basis, net revenue was up 2.3%. This is lighter than our historical results, but given the level of disruption over the past 90 days, as we've integrated two sales teams and commercial organizations, I'm pleased with the results nonetheless. While our commercial integration efforts continue, I anticipate revenue accelerating into the fourth quarter as we stabilize territory and resource alignment and sharpen our commercial execution. Adjusted EBITDA for the third quarter was $34.8 million, as you can imagine there are a number of moving pieces given the merger activities in the quarter and Mike will address the earnings performance in a few minutes. I would highlight that there are a number of areas in which we have harmonized our accounting policies, which creates some year-over-year comparison challenges. Mike and I are aligned that we will deploy conservative and consistent principles that will build on the strengths of our improved capital structure. And we will strive to be as transparent as possible with our external stakeholders. One of the key merits of the merger has always been cash flow potential of the combined organization and despite merger related outflows in the third quarter; we increased our cash balances and finished with more than $50 million on the balance sheet. I am comfortable with our capital position at the end of the third quarter and the performance reaffirms our belief in the cash generation potential for Option Care Health. Stepping back for a minute from the quarterly results, I want to remind everyone of the merits of the merger between Option Care and BioScrip and the opportunity that lies ahead. Option Care Health is the nation's largest independent provider of infusion services in the alternate site setting. With a network of over 120 compounding pharmacies and approximately 2,900 clinicians, we are licensed in all 50 states and have unparalleled ability to reach approximately 96% of the US population. The investments we have made in our people, infrastructure and technology enable us to scale up rapidly and raise the level of infusion care going forward efficiently and effectively. We've talked about the economic justification for the merger and the costs energy potential, but I'm also excited about the opportunity to collaborate with our payer and health system partners to help drive better outcomes for our patients. Providing infusion therapy under our model traditionally costs a four to a third of what it costs to provide similar treatment in the acute setting. So we are energized about the leveraging our scale and clinical expertise to disrupt the traditional paradigm of delivering infusion and settings that are more expensive. And transitioning these patients on to service in the home or one of our 150 ambulatory treatment sites. Finally, I'd like to spend the remainder of my time this morning providing an update on our integration efforts today. Shortly after we announced the merger in March of this year, we established an integration management office with dedicated resources to begin developing our integration plans to hit the ground running and the team has done just that. We knew that any successful merger requires the team to establish a North Star that will guide decisions and actions across the organization. To move with speed and reduce uncertainty, to find a blend of best practices across both entities and to provide frequent clear and honest communications broadly to all team members. As we've approached the incredibly complex integration, highly effective and compassionate patient care has always been at the center of both organizations. And will continue to be our North Star in terms of focus. Every one of our team members understands that there is a loved one on the receiving end of everything that we do. And this has been a galvanizing aspect as we bring the two teams together. While at the same time we are acting with a sense of urgency to integrate the organizations as quickly and effectively as possible. Before the merger was completed, we had already identified the new executive leadership team which was a blend of the two legacy organizations. And as we have announced virtually all leadership positions sub layer or deep it's been a best athlete drill across the board. And we've created a tremendous team splitting roughly 60/40 across the legacy Option Care and BioScrip organization. It is truly an extraordinary organization of talented professionals who share my passion for delivering extraordinary service to the patients with whom we are entrusted for their care. We also committed to the concept of best of both, whereas we entered the merger with a belief that we had much to learn from each other, and we would be begin to build the integration planning process with an openness to take the best practices from either organization. Since the transaction closed, we've established our organizational leadership model, and I've identified all key leaders for the respective area. We know that accelerating top-line growth is critical to our success in integrating and reorganizing our two commercial organizations is critically important. From day one post merger, we initiated a comprehensive review of our combined customer base. The market opportunities and the appropriate alignment of our resources to maximize our reach. Given the focus of the team, I'd estimate we are 80% complete in realigning of our field sales team as of the end of the third quarter. This is one of the more complex areas to harmonize as we have considerable territory overlap. We reassigned and redeployed resources where we can, but there's no avoiding the disruptive nature of this exercise. We estimate that 45% of our commercial organization has a territory or new portfolio of accounts as a result. It just underscores the commercial alignment efforts will take time, but as I said we've made tremendous progress today. The goal of this exercise was to increase the reach and frequency of our selling resources and based on the analytics and monitoring we have in place, we are seeing early signs of achieving these targets. We've also made considerable progress on our procurement efforts today. As we've consistently highlighted procurement as a shorter runway to capture and realize synergies. This is broader than just taking best contract and negotiating a price. As Mike will highlight, we've made progress and get incurred with vendors on past two invoices which has afforded us a platform from which we can form more collaborative and productive relationships with our procurement partners. We have initiated contact with all of our key commercial payers to begin harmonizing contracts and to start work with some of the more innovative health plans to design programs that not only encourage the best site of selection, but also enhance the value for member, payer and us as the provider. I'm also pleased with that our efforts to drive operational efficiencies in the field are taking shape. As we've mentioned previously, we estimate that integration of our operations will take to 18-24 months, as the complexity around system integration, pharmacy licensure; credentialing and overall service continuity is significant. We have considerable experience in this area and ensuring seamless patient care and high service levels for our referral partners and payers is the priority. To date, I am very pleased with the multifunctional efforts to begin standardizing our field operations that will generate a more efficient and effective model. One of the initial activities for the clinical team was to standardize the quality management system for all our facilities and to prioritize and deploy capital to eliminate any deferred maintenance and to bring the entire fleet of facilities up to the same high standards. This process is well underway and we have made strong progress in deploying standard operating procedures, supporting technology and making facility upgrades where appropriate. As you know, revenue cycle management is a vital component in driving our financial performance. Both organizations have placed a significant amount of focus to stabilize and improve the performance of these functions. As I mentioned earlier and as is apparent in our statement of cash flows. We have seen improving velocity of cash collections across both organizations as we increase the productivity and effectiveness of our efforts. We still have a significant amount of work ahead of us to drive better than historical results, but we are building and executing plans to utilize technology and more effectively deploy resources to increase the speed and accuracy of our claims submission. Throughout this entire process, both pre closed and since, we've worked tirelessly to provide a constant stream of communication to our team members to ensure that everyone is up to speed on the integration plans and how it may affect them. We have engaged teams from across all disciplines and from both legacy organizations to help us define, describe and communicate the purpose, mission and values of Option Care health. And we are finding ways to identify and recognize team members who are modeling the desired behavior and living the values. So a few thoughts in closing. We know that a successful merger of this size and complexity requires disciplined execution. So it's early and in no way are we over the hump, but I am very encouraged by the progress to date and that we are on track with the plans that we've established. We have a significant amount of work ahead of us, but I've never been more excited about our team, our enterprise and the opportunities that lie ahead. With that I'll turn the call over to Mike to walk through the third quarter results. Mike?
