I never hear from him when I call him. His computer is more important to him then his patient that's a shame I wish the other never left she listens to you he doesn't you sit there for 10 minutes waiting for him and he's done with you in 5 second he always have excuses, no mri no nothing to find out why you're hurting just take over the counter medicine yet the patient is hurting. Don't understand guess his computer is more important to him then his patient Today is June 30th and I had to call his office back they sid that they called me and they did not called me I had my phone on no calls and no messages 😑 and they're sending something over from the drug store 😔.

It is impossible to get them to answer the phone and refill a simple prescription. They are extremely below average returning phone calls and do not inform you of anything before it happens. It is my recommendation that you find a different place to go to if you would like proper medical treatment

He was dismissive, spent more time on his computer. While I was telling him of my issues, I’ve seen him before, he felt our less than five minute visit was complete. As he was walking to the next patient, I had to get his attention to find out what to do, his dismissive comments were “take Tums” and walked into the next room. So very unprofessional and uncaring!! He never looked at me one time. 🤬🤬. Would never recommend him to anyone!!

Getting a prescription refilled through this office is absolutely ridiculous. Multiple calls with voicemail’s from me and pharmacists never returned. Pharmacist also faxed in multiple requests to have prescription filled. Still nothing. I don't know if the Doctor's office is completely overwhelmed with work, or just lazy, but the result is the same. When you need prescriptions or information, you can't get a hold of anyone.
