Newton County, Georgia
Time for your questions, from a urologist who listens
Prostate symptoms, a PSA result, erection changes, low energy: these are easier to talk about with someone who listens. Our urologists make time for those conversations at our Conyers Clinic, 1366 Wellbrook Circle Suite B.

How do we care for the prostate and bladder?
For Covington, Oxford and Porterdale, these are the concerns we help with most.
- Enlarged prostate (BPH). We match treatment to how much your symptoms bother you, from medicines to procedures at our Snellville surgery center.
- Overactive bladder. Urgency and frequency are common in women and men, and very treatable.
- Prostate cancer. From an elevated PSA and a prostate biopsy to a treatment plan, our urologists guide you through it.

How do we help with men’s health?
Enlarged prostate. A weaker stream, trouble getting started, getting up at night: these can come from benign prostate enlargement. One of our urologists can assess it at the same appointment, and treatment ranges from habits and medicines to procedures done in Snellville.
A PSA result. A higher number tells us to take a closer look, but it doesn’t settle anything by itself. Our urologists explain what the number means for you and what, if anything, comes next.
Erectile dysfunction. Because erections depend on blood flow, ED deserves a real evaluation; it can be linked with heart and blood-vessel health.
Low testosterone. Testing comes first, then a conversation about options if treatment fits.
Women are seen in Conyers too, most often for bladder urgency and leakage.
