Hi, I'm Dr. Jeffrey Mark, M.D., a gastroenterologist and functional medicine expert with over 30 years helping people just like you get back to feeling their best. I've dedicated my life to fixing gut health issues, balancing hormones, and tackling heart and energy problems from the root cause—not just masking symptoms with endless meds. My own story started young: At age 10, a bad infection from travel nearly took my life due to a wrong antibiotic, sparking my passion to help others avoid that pain. Later, in my 40s, I battled fatigue, weight gain, high blood pressure, and brain fog from heavy metals and mold toxicity. Using functional and regenerative medicine, I healed myself and now share those tools with you. I earned my B.S. in Neurophysiology from Northwestern University, my M.D. from the University of Illinois College of Medicine, did my internal medicine residency at Northwestern, and specialized in gastroenterology at Chicago Medical School. I'm also certified in medical acupuncture from UCLA and 5X board-certified in functional medicine, anti-aging and regenerative medicine, gastroenterology, obesity medicine, and internal medicine. This lets me blend the best of traditional care with cutting-edge therapies like peptides, PRP, exosomes, and personalized plans. At The Real Gut Doctor, my focus is you: We create custom diets, supplements, and lifestyle tweaks to restore your vitality, mental sharpness, and joy. Whether it's beating IBS, colitis, or low energy, I've guided countless patients to ditch meds, heal after surgery, and live fuller lives. No extreme diets or guesswork—just real results.

Ashley Kitchens, MPH, RDN, LDN, is a nationally recognized plant-based dietitian, spokesperson, and nutrition consultant. Ashley founded her company "Plant Centered Nutrition" with the intention of providing approachable plant-based nutrition information to her clients, community, and media audience. Ashley is regularly seen in national media outlets such as Fox News, VegNews, Vegetarian Times, Eating Well, The Times Weekly, Forbes, Newsweek, and Health.com, providing comments and education on various nutrition related topics. She is a trusted source with over 10 years of experience practicing as a plant-based dietitian. She also partners and collaborates with plant-based friendly brands through social media, speaking engagements, her podcast, and many more platforms. Ashley grew up on an Angus cattle farm in small-town Indiana. As you might guess, meat and dairy were a big part of daily life. Unfortunately, so were GI issues like chronic constipation. For years, Ashley was told to manage her issues with medication instead of considering the food she was putting into her body. Ashley earned her Masters of Public Health and Nutrition from the University of North Carolina at Chapel Hill and became a registered dietitian in 2012. But, even after all that, her GI issues didn’t completely go away. It wasn’t until she did personalized research to dive deep into her own life and her own eating habits that she noticed a significant change. For her, this meant transitioning to a plant-based lifestyle. After that transition, she knew there were others who could benefit from a diet filled with more plants. She also knew it was critical for the coaching they received to be based on a deep understanding of their unique situation. That’s when she realized why she became a dietitian. Ashley made it her mission to help others transition to a plant-centered way of eating through a holistic approach and intuitive eating practices.
