Six week time frame to get an appointment. Dr. Koumas rarely in the office. Loves to prescribe pills to old people to move them in and out. Even when the patient doesn't know where they are, who the president is, she'll prescribe a pill and watch as the patient hands behind the driver seat getting ready to drive! No conscience this doctor.

Doctor Mary has been our family doctor for over 23 years and she is the best. Typically runs late, but the wait is worth the care she provides.

There are so many words to describe Dr Mary Koumas, but AMAZING would be the most appropriate. I have been seeing Dr Mary since 1988. She is caring, ...

Dr. Koumas is by far the best doctor I've ever seen but had to stop seeing her after many years for many reasons. The Pros- Dr. Mary Koumas is an excellent doctor, very caring, very knowledgeable and spends a good amount of time talking to you to understand the problem.The Cons- Her staff is terrible. The front desk is extremely curt, brusque, unfriendly and rude. Another issue is the wait time. Expect to wait between 45 mins - 1.25 hrs if you're seeing Dr. Mary (as she is know by her patients since her brother is also a doctor there). Even if you book the 1st appt. of the morning, there will be 2 or 3 other people booked at the same exact time as you!!! If you start your day by triple and quadruple booking like that, OF COURSE it's going to snowball throughout the day, EVERYDAY.It's too bad b/c Dr. Mary is an excellent, excellent doctor & I would have loved to continue seeing her as my doctor. It's been awhile but I haven't found a dr. I trust as much as her.I could have suffered… the unfriendly staff but the wait time just drove me nuts!
