I saw Dr. Goodman for my diagnoses..... He is a really great guy he's understated and quiet but extremely smart and a great listener. He is very thorough and depending on your other complaints will send you for a full batch of tests. For POTS in general in me he did a qsart,tilt table (neuro not cardiac) catacholomine test, movement studies test, holter moniter, 24 hour bp moniter, and mri, as well as a ton of blood work to rule out everything under the sun and check on your levels. He definitely knows what he's doing and is a great guy and will follow up with you over the phone after your visit and his nurse Janie is great also. Hope this helps
