I have not even been in to see this Doctor yet and I am regretting making the appointment. I live 3 hours away and can not even get anyone on the phone. Took 3 days of endless calling to make an appointment. I have been on hold NOW for 15 mins collectively. Hung up on 3 times and when I called back the last I got "thank you for calling can you please hold?" I said no ma'am I have been holding and have been hung up on 3 times. She says "OH well hold on" that was 7 mins ago now.

He seemed nice enough but I felt a tad rushed with my first visit with him. Once my visit was done and it came to talk about returning he informed that I would not see him any more but his PA. I don't mind PA's but I have an issue with paying the same amount to see a PA as the doctor. I did not return.

I like his treatment approach. His staff is an entirely different matter for the most part. His medical assistant takes a very long time to get back on any messages - matter of fact her vmail states something to the effect "don't leave more than 1 vmail I'll get to you". I can't imagine having that on my work vmail! Front desk staff not much better - can't be bothered and have zero compassion. Not fit for a job in the medical field.

I agree with others, I like Dr. Leffert but the wait times and trying to reach out to the clinic is a cat and mouse game to get to actually talk to someone. I get no response and just get frustrated that no one can help me and when I am coming in the office it's always a LONG 2 hour or more wait to see the DR.

Dr Leffert is a fine doctor, but scheduling and wait times seem to be problematic. The shortest wait time I have ever had was 90 minutes, but usually is around 2 hours. Then when I do see the doctor the appt has never been more than 10 minutes. I understand that doctors can run behind, but the staff should call and let the patients know so that they don't have to leave work and sit in the waiting room. Telling the patient the doctor is running late after arrival at the office is pointless.
