You might work with an occupational therapist when you’re injured or if you have a disability. They rehabilitate and assist patients with every day activities, such as eating, getting dressed, working and attending social events. This includes self-care, leisure and work-related activities that lead to increased independence and development. Their goal is to empower people to still live the life they want despite any physical, developmental, social and/or emotional issues they might face.

A preventive medicine/wellness specialist is a physician who, through additional training, has become an expert in methods for maintaining good health and preventing disease. These specialists are the doctors people see when they are generally well or without a specific ailment and want to either learn how to maintain their current health or acquire better health.
These doctors will advise patients on specific diets, exercise regimens, and lifestyle habits that are suited to their particular needs. Preventive medicine/wellness specialists take into account a patient's nutrition deficiencies, physical and cardiovascular capabilities, and habits in order to advise specific vitamins and supplements to take, how much physical activity to undertake, and which habits should be broken and replaced with more positive behavior.

An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.
In addition to treating the common cold and flu, internists also treat chronic diseases like diabetes and heart disease.

A family practitioner is a doctor who specializes in caring for people of all ages, at all stages of life. Rather than focusing on the treatment of one disease or patient population, family practitioners are often the doctors that people see for their everyday ailments, like cold and flu or respiratory infections, and health screenings. When necessary, family practitioners will provide referrals for conditions that require the expertise of another specialist.
The doctors may also provide physicals, inoculations, prenatal care, treat chronic diseases, like diabetes and asthma, and provide advice on disease prevention.
