My Philosophy and Approach to Wellness...

The core of personalized health care is an excellent patient-doctor relationship. Time and communication are key elements to evaluating the whole individual. As an MDVIP-affiliated physician, I have the time to listen to my patients in order to fully understand their unique life experiences, address their needs and concerns, perform a comprehensive medical screening examination and develop a personalized health and wellness plan that I would not be able to provide in a traditional medical practice. 

I am a native Dallasite and have practiced internal medicine and geriatrics for over 30 years. I am board certified in internal medicine with added qualifications in geriatrics. My practice is based at Texas Health Presbyterian Hospital of Dallas. My expertise includes cardiovascular medicine, diabetes, hypertension and preventive medicine.

I have achieved many awards and accolades over the years, but my greatest satisfaction comes from my patient interactions. Let me help you reach your personal goals for your health and well-being.

Testimonials from patients of Dr. Fleschler

from Gabriel in TX December 19, 2022 for Mark J. Fleschler, MD, FACP

The day after I came home from open heart surgery, I went to Dr. Fleschler for total body swelling and a cardiac rhythm disturbance. From that time on, Dr. Fleschler helped to "pull me through the knothole." He literally managed my recovery day to day. His kindness and expertise are so appreciated!
