      Holly DeFazio's Review Sourced from Google

      We could not be happier with the service we received from Dedicated Designs/Three29. Josh and Courtney were absolutely delightful to work with. We had the pleasure of working with both Josh and Courtney on the redesign of our website. They both came with a wealth of information, creative ideas and patience. They took the information we gave them and came back with a finished out, easy to navigate website design that flows seamlessly. We could not be happier! We continue to work closely with them on edits and updates to our website today. We highly recommend them for any of your website needs. The CLTRE Team

      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!
