I work for a large practice that routinely refers patients to Dr. Koka. As such, I've sent plenty of friends and acquaintances to see him. I recently booked an appointment to see him for a nagging issue (occasional palpitations), and so far, I don't regret any of my referrals. The office staff is efficient, his RN, Andy, is great and appointments are easy to come by. Dr. Koka himself seems to be a smart, straight to the point diagnostician. At this point in my workup, I'm very pleased with my selection. (Also hoping I have no additional experience with the office after I get rid of this Holter monitor next week!)
