In the current healthcare climate it is imperative that all facilities, including hospitals, doctor’s offices and surgery centers be keenly aware of their expenses and be ever vigilant to keep their expenses in check and diligently strive to reduce their cost. While cost conscious intervention is crucial, increasing revenue is paramount and should be every business focus. The business plan of Medical Consulting Solutions, Inc. (MedCoSo) is accentuated/complimented by an affiliate relationship with MedAssets GPO and a synergy with multiple medical suppliers and service oriented companies. The overwhelming strength of MedCoSo is its ability to create significant revenue streams through proven clinical management and delivery systems. Our CEO has proven this to be true throughout his clinical career in the field of anesthesiology. Under his leadership the companies under his watch have experienced compounded growth since their inception.

Market growth in the field of Office Based Surgery Practice has grown over 300% in the past ten years. With the certain advent of Accountable Care Organizations (ACO’s) we believe the thrust of coordinated patient care in the least cost environment will provide an additional opportunity for unprecedented growth. MedCoSo provides leadership to help its clients through this period of healthcare uncertainty.

Specialties: We are an affiliate of MedAssets (largest Medical GPO) and offer over 2500 vendor contracts. Our contracts are inclusive of manufacturers, distributors as well as service oriented contracts. We strive to bring ideas and programs, which provide increased revenue by creating multiple profit centers throughout the practice. As a result, the practice viability is evident and practice value is enhanced.
