Book Your Neurologist Visit →Why Synapse
Precision isn't a promise. It's the product of 15 years of seeing what others missed.
Dr. Mercer built Synapse as a single-practice model deliberately — to spend the time that a large hospital system cannot. Every appointment is 60 minutes. Every scan is read personally. Every diagnosis is explained until it makes sense.
Most insurances accepted. No referral required for self-pay.
