- State Sanctions
- Federal Sanctions
- Disciplinary Actions
Disciplinary actions are actions taken to punish or restrict physicians who have demonstrated professional misconduct. HealthGrades reports state and federal disciplinary actions (if any) from the previous 5 years except when a physician's license has been revoked or surrendered.
Physicians with a disciplinary action in one state will often move to another state where they may have a clean record. Since HealthGrades painstakingly compiles disciplinary action information from all 50 states, you'll know if a physician has an action in more than one state.
Board Certification- Is your physician board certified?
- In what specialties is your physician certified to practice?
Certification lets you know that a physician has gone above and beyond what medical licensure requires, receiving additional training and examination to be certified in a particular specialty.
A physician who is not board certified may still be an excellent physician. Some physicians choose not to apply for certification. If you are considering a doctor who is not board certified, it may be important to know why he or she is not certified.
Certification lets you know that a physician has successfully completed an accredited educational program, passed several evaluations, and possesses the knowledge, skills, and experience needed to provide care in the certified specialty. Once certified, physicians must attend continuing medical education programs throughout their careers in order to remain certified.
Education- Medical School
- Residency Training
- Internships
Physician education and training is demanding and extensive. Continuing medical education is a life-long pursuit due to constant advances and changes in medicine. With HealthGrades, you'll know if your physician is keeping up with all the latest technology.
The longer a physician has been practicing, the more likely that he or she is experienced with a wide variety of issues. A more recent graduate, however, may have in-depth knowledge about medical advances for treating a specific condition.

General Surgery
General Surgery
General surgery can be performed on almost any area of the body. A general surgeon is a physician who performs surgery and provides preoperative, operative, and postoperative care to surgical patients. This surgeon can treat diseases, injuries or deformities by surgery or minimally invasive techniques, such as endoscopy, where a tiny scope is used to view internal organs or structures. The endoscope can be used during operating procedures, or before surgery, to diagnose, assess and treat problem areas. -
Colon & Rectal Surgery
Colon & Rectal Surgery
Colon and rectal surgery deals with the intestinal tract, the colon, rectum and anal canal. A colon and rectal surgeon diagnoses and treats various diseases of these areas of the body by medical and surgical means. This specialist may deal with other organs and tissues that are affected by intestinal disease, such as the liver, urinary, and female reproductive system.A colon and rectal surgeon can also diagnose and manage conditions such as hemorrhoids, abscesses and fistulae (infections located around the anus and rectum), Crohn’s disease, ulcerative colitis, and other inflammatory conditions. They also use technical procedures to evaluate and treat cancer, polyps, and other anorectal diseases.
