Hi Marcella, congratz!!
My gynea is Dr Q Ndiweni, he practices in Clinix Tshepo-Themba Private Hospital, Netcare Garden City Clinic and Moningside Medi-Clinic and he charges medical aid rates. I don't know if he does go to LenMedHere are his Tshepo-Themba details: 011 988 9372.
As for LenMed, I have never been there, sorry. I delivered in Garden City when I was still staying in Soweto. I would really recommend it, their service is great.
Good luck with your pregnancy.
