I know Dr. Emer markets aggressively but I have personally not reached out to their Clinic regarding Sponsorship because I felt their approach wasn't a good fit for the PhalloBoards. He comes off a bit too much like a
celebrity doctor and has overhyped his qualifications in this field.
Like the original commenter said, I get the impression the Clinic is a revolving door in many different respects. As for his work & patient care, I really can't speak much on it since I haven't seen enough credible reviews to draw judgment. What I do know about him is that he can sometimes be difficult to get a hold of directly.
Honestly, if you are going to a practitioner in Los Angeles or Orange County (the area Dr. Emer operates) for injectables, and want a Doctor you can reach directly,
Dr. Tsay
is a no-brainer. He's extremely well-reviewed with the use of injectables (see his Yelp & Google Reviews), has really expanded his male enhancement work, and will talk to you personally over the phone if you are on the fence and need questions answered.
