Thyroid doctor in Dallas

Liz
Hi everyone! I'm looking for a good thyroid (endocrinologist) in the dallas area and hoped someone had a recommendation! Thyroid issues run in my family but my primary care doctor tested me and said my numbers were on the low end of the normal range. I want a second opinion. 
Losing weight is hard for me despite a strict diet, exercise, and doing everything I should to lose weight. It's starting to really depress me and I want to figure out what's wrong and what I can do to fix it. Thanks!
