5.0 star star star star starDr Later genuinely cares about his patients. From caring about RX costs and providing discount cards and samples to truly finding a treatment plan that works. I never feel rushed. My quality of life has greatly improved since I started seeing Dr Later.

5.0 star star star star starDr. Later gave me an appointment after my doctor's office contacted the neurology dept. He was very thorough and very personable and very knowledgeable. I would recommend him without a hesitation. He never rushed through the examination.

5.0 star star star star starLike I’ve mentioned before I’ve always felt woman are more compassionate. He’s one of the few doctors not knowing me talked a lot to make me feel comfortable. I’m a person who is hard to get along not friendly at all.

5.0 star star star star starThis is my first time seeing Dr. Later because Dr. Ashaye was on family leave. I came away from the appointment feeling relieved and very well taken care of. With Dr. Later's recommendations, I'm excited to try new drug therapies with less side effects.

5.0 star star star star starI have seen both Dr. Ashaye and Dr. Later. Both physicians are easy to relate to and have actively listened to my concerns before recommending a treatment plan. I come away knowing I was an active participant in my care. I intend to stay with the group going forward. I'm well taken care of. I believe many of their patients feel the same way as there is a bit of a wait to get in to see them.
