Dr. Joel A. Hoffman has been practicing as an Ear, Nose and Throat specialist in the Cumming and Roswell area for the past 25 years. Dr. Joel A Hoffman is a double board-certified physician specializing in rhinology (nasal and sinus disorders) and sleep medicine.

Dr. Hoffman has helped develop an innovative procedure (nasal valve suspension suture) to correct nasal valve obstruction. Having performed over 1200 cases with a greater than 90% success rate, Dr. Hoffman is able to relieve nasal obstruction in many patients who fail traditional nasal surgery (correction of a deviated septum and reduction of the turbinates).

Experienced in advanced sinus techniques (image guided sinus surgery and balloon sinuplasty), Dr. Hoffman offers the latest technology to correct some of the most difficult nasal and sinus problems. Read More About Dr. Joel Hoffman.

Dr. Mark B. Van Deusen is trained in all aspects of otolaryngology and sees patients in both Alpharetta and Cumming. His passion for practicing otolaryngology is evident in his many interests. He enjoys treating patients with sinus disease, nasal obstruction, and allergies. When medical management fails, Dr. Van Deusen is skilled in endoscopic sinus surgery, Septoplasty, and rhinoplasty techniques. In some cases, Dr. Van Deusen is able to perform in-office sinus procedures to improve sinus drainage and improve nasal breathing. Read More about Dr. Mark B. Van Deusen.
