Dr. Luecha is great
*Dr. Luecha really listens to me. That is a valuable asset for any doctor! I really appreciate her and her staff.
Dr Leucha listened to my concerns this time.
I have recommended & knew patient likes St. Jude.
I appreciate all of the good qualities expressed in the above questions that Dr. Luecha possesses. Some of these are lacking from at least one of the Rose Drive doctors for which I have had a bad experience. This makes me appreciate Dr. Luecha's professionalism and "bedside manner" even more.

Physician Bio

As a family physician, the most rewarding aspect of my practice is helping families to grow and thrive. I often see several people from different generations of the same family. I view the relationship with each patient as a partnership toward better health and believe in treating the whole person—mind and body. I’m passionate about caring for families—from pediatrics and well-woman care to geriatrics—whether they have a common health issue or a serious chronic condition. It’s a joy to help them achieve and maintain good health.
