We Represent Doctors in All Areas of Medicine

We work with all types of doctors and practices, including:

Practice Formation

If you are ready to form a medical practice, call Arenstein & Andersen Co., LPA. Depending on your desired practice, your business partners, and your short- and long-term goals, we may recommend you form a:

The formation of separate legal entities is essential to protect yourself, your family, and the well-being of your practice. We know the ins and outs of Ohio and federal law with regard to medical practices and are highly experienced in building medical practices from the ground up.

No matter what type of care and services you provide, we will advise you on which entity best serves you and gives you the ability to manage and grow your practice smoothly.

Once your entity has been properly registered, we will work with you and any other owners to draft appropriate governance documents, including by-laws, close corporation agreements, operating agreements, buy-sell agreements, shareholder agreements, or partnership agreements tailored to your needs. We will also help you with your tax considerations, including whether your business should elect to be taxed as an S-corporation or a C-corporation. We will help you decide how your practice will function and solidify your decisions in writing.

Finalizing Practice Agreements

The corporate practice of medicine is much more than choosing and creating a legal business entity. Once your practice is established, you must:

Many of these tasks require negotiating, drafting, and finalizing agreements. If you are going to work with other doctors, you will need shareholder/physician employment agreements and buy-sell agreements. You will need employment agreements with your employees, including other medical professionals and specialty staff. You will need contracts with vendors and other businesses or professionals you will regularly work with.

When it comes to contracts related to a medical practice, you should never sign on the dotted line without an experienced lawyer’s help. If you are provided with a contract by another party, we are here to review that draft carefully and negotiate appropriate changes. We also can draft contracts for your practice to provide to potential partners, employees, or vendors.

Purchasing an Existing Practice

You may not want to start a medical practice from scratch and, instead, purchase an existing practice with an established reputation and client list. Or, you may plan to expand your practice by acquiring an established operation. Additionally, you could join an existing medical practice with the intention of taking over one day.

Whenever you come into or take over an existing practice, you face a complicated process. You need to talk with a mergers and acquisitions lawyer who has experience in the medical industry.

Our attorneys are here to assist you with practice valuations, due diligence, financing issues, contract negotiations, closing the sale, and transitioning into your ownership position. We are here to guide you in making decisions based on facts and figures – not your emotions. We want you to find the practice that is right for you now and years down the road.

Managing Your Practice

Once your medical practice is established, or you have successfully transitioned into an existing practice, the work is far from over. If you have a corporation, limited liability company, limited liability partnership, limited partnership, or professional corporation, you must maintain your corporate formalities.

Our experienced business lawyers are here to help you remain compliant and organized. We will assist you in maintaining excellent and secure patient and financial records as well as advise you on the growth and direction of your practice.

Not only must you be a healer, but you also have to be the owner and boss. You have to professionally and effectively manage your staff. This entails implementing lawful recruiting, interviewing, hiring, and employment practices.

We recommend creating a comprehensive employee handbook. This handbook should include information regarding Ohio and federal employment laws that you must comply with, as well as your and your employees’ rights and responsibilities.

At Arenstein & Andersen Co., LPA, our medical corporation lawyers are well-versed in Ohio and federal employment law, including:

If an employment dispute arises, we can guide you through resolving the issue. When necessary, we can represent you in civil litigation.

Additionally, we are here to help with any real estate and landlord-tenant issues. If you rent space for your practice, we will help you address any issues that arise due to renovations and buildouts, rent and utility payments, maintenance and repairs, and more.

If you are interested in moving to a new or bigger space, we can guide you through the real estate purchase, renovations, or building process.

Healthcare Laws and Compliance

As a doctor and medical practice owner, you need to be aware of Ohio and federal healthcare and insurance laws, and how to maintain regulatory compliance. The best way to do this is to work with an experienced medical corporation lawyer in your area.

At Arenstein & Andersen Co., LPA, our attorneys are knowledgeable regarding:

By working with our experienced medical practice lawyers, you remain up to date with federal health care laws, which ensures you avoid poor results of audits by state and federal agencies or litigation. If you are the subject of a complaint, investigation, or audit, we are here to help you cooperate while protecting your practice and license. We are experienced in working with federal regulatory agencies to resolve issues as swiftly and fairly as possible.
