Dr. Amie Stringfellow

Dr. Amie is triple board certified in Internal Medicine, Pediatrics, and Sleep Medicine. After five years of private, insurance-based practice, she felt she could best serve her patients by switching to a Direct Primary Care model of medicine, where she has more time to connect with and care for her patients, which is the core of her life-long desire to enter the field of medicine.

Dr. Amie graduated from medical school at the University of Texas Health Science Center at Houston. She went on to complete her Internal Medicine/Pediatrics residency and Sleep Medicine fellowship at Baylor College of Medicine in Houston. She is also an FAA certified Aviation Medical Examiner (AME) and HIMS AME.

She is married, has 1 adorable daughter, and loves to spend time with her family and friends. She also enjoys reading, scrapbooking, and spending time outdoors.


Dr. Ana Molina-Anstee

Dr. Ana joined Milepost Medical in January 2018 to pursue a new path in direct primary care (DPC). DPC will allow more individualized care, which means more time with her patients and better care.

She specializes in Internal Medicine and Pediatrics and speaks both English and Spanish.

She obtained her Bachelor of Science in Biology from Baylor University in Waco, Texas in 1997. She also has a Masters of Science degree in Biology. Dr. Ana went on to earn her medical degree from Temple University School of Medicine in Philadelphia, PA in 2004. Afterwards, she returned home to Texas for her residency training in Internal Medicine and Pediatrics at the University of Texas Medical Branch in Galveston, which she completed in 2008.

Dr. Ana enjoys aspects of both specialties, but is specifically interested in preventative medicine and natural healthcare solutions, including incorporating essential oil use in modern medicine. She also has an interest in treating obesity and diabetes in all ages.

Dr. Ana is married and has 2 young daughters, 3 dogs, and 1 cat (all rescues). Outside medicine she enjoys spending time with her family/friends, reading, watching TV/movies, crafting, and sharing information about essential oils.
