Dr. Susan Cox Ahern is the most professional, personable, delightful medical doctor that I have ever entrusted with my health needs. Not only is she on top of the latest advancements in the field, but she is very good at seeing through any attempts that I might make to bluff my way past her investigative questions. She forces me to be honest with her. I only wish that I could have started our professional relationship earlier in my life to correct the bad pathways that I chose.

I see her as part of the PRO weight loss program. I appreciate her questions and support and advice. She is always up-to-date on my medical issues and builds upon the prior visits.

5.0
Dr Ahern is so well-versed in endocrinology and related fields that it instills a relieving sense of confidence in me. After visits with her, I have the feeling of comfort in knowing that I can trust what she says and suggests. She’s thorough in her explanations and in her responses to my questions. She’s shows compassion and concern. She’s an excellent doctor.
