We have been using Ketamine Lead Gen for 8 months with our clinic- New Pathways Clinic. Right away we were impressed with their knowledge and expertise in the Ketamine/Spravato space. They have helped us navigate this complex marketing/advertising space and have fantastic ad copy for those who need it. Really appreciate what the owners Jake and Steve have done for our practice!
