    Ashley Dearstine was amazing! Her knowledge about hEDS, MCAS, nutrition, and other topics was very impressive. Ashley was very engaging, listened intently, showed concern for my issues, discussed tests and treatment, and was completely wonderful! I've already been recommending Ashley to others. I feel very fortunate to have the opportunity to be seen by Ashley.
