What Our Clients Say


AHC has been in business for nearly 30 years.  We are a leader and well respected brand with hospitals and other referring providers.  However, we had not paid much attention to the ever evolving payer landscape and found that we were declining more referrals than we could afford and needed to participate in more health plan networks.  The O’Sullivan Group quickly identified the gaps and caught us up with contracts that positioned AHC to better serve our hospital clients and serve more patients.

Ridge Smidt, CEO and Founder

Arizona Home Care

The O’Sullivan Group was instrumental in bringing our innovative specialty hospital model to managed care plans that we’re not familiar with our benefits and value proposition. They understood our urgency in getting contracts in place without sacrificing appropriate reimbursement terms.

We retained The O’Sullivan Group for managed care consulting services for over 10 years and primarily work with Brian O’Sullivan. In our experience we found Brian to be diligent in his follow through in negotiations with contracting representatives from the managed care plans. Brian invested the time in understanding our business and specific needs. He was well connected in this arena which allowed him to identify the point of contact to facilitate the negotiations. He was particularly astute in reviewing the contract language and making recommendations for suitable alternative language. He has a talent for identifying common ground for both parties to facilitate a mutual beneficial agreement. Brian consistently provided regular detailed communication regarding his efforts. We found Brian to be professional and effective in fulfilling our contracting requests.

As a 30 plus year old hospital-based radiology practice, we realized that in order to survive we must grow and innovate.  In the last 12 months MDIG has expanded to 5 new states and added an outpatient interventional radiology procedure lab.  I was eager to make sure our contracts were at market rates.  I did not have time to provide much direction.  The O’Sullivan Group came in and interviewed me to learn my vision and translated that into an action plan.  They became like a direct report to me and freed me up to focus on lead, manage and grow the practice.  The O’Sullivan Group has been instrumental in identifying, soliciting, negotiating and securing the managed care contracts to ensure that we have the revenue streams and appropriate reimbursement rates to support our success and serve our hospital and patient clients.

Patrick Santore, CEO Medial Diagnostic Imaging Group


The O’Sullivan Group has been instrumental in introducing the innovative Sante rehabilitation model to the payer market. They subsequently helped us add home health, hospice and outpatient therapy programs as Sante became a broader post-acute provider. They are a valuable resource, sounding board and trusted partner as we continue to innovate, adapt and grow.

C. Mark Hansen,
President and CEO


With a new executive team, the Board was looking for a significant financial turnaround.  We were losing physicians and struggling to recruit and pay new talent.  I had worked with The O’Sullivan Group previously and knew they could deliver results and work under the pressure of a tight timeline and build the confidence of our Board.  Within 6 months we were able to renegotiate our largest managed care contract to market rates and realized significant ROI.  From there we brought our other contracts in line.  Ultimately the increase in revenue stabilized the practice and resulted in significantly higher valuation in a joint venture relationship with an integrated hospital system.

Chuck Ribbe, Chief Financial Officer, The Orthopedic Clinic Association


Vasco has grown from a local compounding pharmacy and expanded to home infusion, specialty pharmacy and statewide infusion clinic provider.  The O’Sullivan Group has been instrumental in helping us explore the opportunities, identify sites, develop practice relationships and developing programs and value propositions to help us secure favorable relationships with managed care payers.

We have used The O’Sullivan Group intermittently to assist our internal contracting team. Brian was instrumental in using his connections and negotiating skills to bring us contracts that we had been unable to acquire on our own. Brian worked with us to create a plan and then sticks to that plan. He effectively communicates progress and status and is fair with his fees. It allowed me and my staff to focus on growing our Company, managing operations, and RCM processes.

Tim Spooner, Founder and CEO, Spooner Physical Therapy

As busy physicians and entrepreneurs, The O’Sullivan Group was critical to accelerate the introduction of our first to market innovation. We knew of their experience in launching other innovative care models in the Arizona market. They took the time to learn our business and understood our urgency in securing favorable contracts with managed care plans. They kept us up to date with issues and developments and involved us in key decision points and meetings as necessary.

Kishlay Anand, MD - President/CEO Partner, CVC

Cardiovascular Consultants


The O’Sullivan Group has been providing managed care contracting, financial analysis and general practice management services for CRA since 2009. They achieved the objective of the initial scope of work and have helped us with strategic projects and regular financial analysis and reporting. Most significantly they have renegotiated our managed care contracts from sub-market rates to appropriate top of market rates. This financial improvement has allowed us to recruit additional physicians to reduce our use of outsourced teleradiology and meet the demands of one of our hospitals becoming a level one trauma center. We can increasingly attract top level physicians to meet the needs of the growing hospitals we serve.
