"I am a new patient with the Rockville Internal Medical Group. I am being treated by Dr. Louisa Ziglar for knee cartilage damage. Her skills in the use of ultrasound guided injections and medical knowledge of bone and joint related diseases are exceptional. Although her specialty is rheumatology, her medical expertise, humanistic approach to treatment protocols, patient care responsibilities, and medical ethics far exceed this designation. I am very fortunate to have Dr. Ziglar as my treating physician. Throughout this process, she has provided extraordinary care in treating my knee issues. Based on my past experience with treating physicians, Dr. Ziglar is unique with respect to her communication skills. She fully communicates clearly and concisely the medical diagnosis and recommended treatment options. I applaud her and her staff for their exceptional communication skills and medical expertise. 5 stars."
