Our ENT Specialists and Audiologists

Thomas Stark, M.D.

Thomas Stark, M.D.


Proud to be a fourth generation Texan, Thomas W. Stark, M.D. went to high school in the west part of Corpus Christi, surrounded by cotton fields and oil refineries. He went to the University of Texas at Austin as a National Merit Scholar and graduated in three years with a B.A. in Biology. (Yes he is a Longhorn). He then attended medical school in San Antonio, graduating with honors.

Dr. Stark then left Texas as a Medical Officer in the U.S. Navy and was stationed at the National Naval Medical Center in Bethesda, Maryland, just outside Washington, D.C., where he trained first one year as an intern in Surgery, then spent four more years there as Residency training in Otolaryngology. He then served in the Navy in his specialty in Okinawa, Japan then Long Beach, California.

Dr. Stark became Board Certified by The American Board of Otolaryngology in 1983. He undertook additional Fellowship training and examination and achieved the status of Fellow in The American Academy of Otolaryngic Allergy in 1989. This national group is comprised of ENT specialists who deal with the complexities of allergy and immunology.

He moved to The Woodlands in 1988 and has been practicing in Montgomery County steadily since then. He was affiliated with Sadler Clinic through 2012, and established his own solo private practice in his current location in July of 2012.

He embraces cutting edge technology, and has extensive experience with modern nasal and sinus surgeries, including the use of sinus dilation balloons and micro-fiber lasers.

His office is equipped for diagnosing allergies with a variety of test techniques. Dr. Stark does still believe that properly performed skin testing is the most accurate of the ways to diagnose allergy. (It can be performed in a painless manner). He offers conventional "shot": immunotherapy as well as allergy drops form of allergy therapy. Sublingual immunotherapy or allergy drop treatment differs from the usual allergy shots regimen in that the drops are placed underneath the tongue. This form of treatment slowly desensitizes you from your hypersensitivity to pollens, dander, mold, dust mites and other allergy triggers.

As a former SCUBA dive instructor and Navy veteran, Dr. Stark has a special interest in the ventilation system that allows us to equalize pressure and "clear our ears" usually called the Eustachian tube. He has traveled both to Boston and San Francisco to learn a novel technique for fixing obstruction in the area with sinus balloon type instruments.

Dr. Stark treats children of all ages, including various pediatric ENT services.

Ross Tonini, Au.D.
Clinical Audiologist

Dr. Ross Tonini has worked in the field of communication for over 40 years as a speech-language pathologist and as an audiologist. He has experience working with all age groups and is fluent in American Sign Language.  He received his clinical doctorate in audiology at the Baylor College of Medicine in 1999 and helped to develop the cochlear implant program at Texas Children’s Hospital.  He subsequently worked in private practice and most recently at Baylor College of Medicine in Houston, Texas with an emphasis on evaluation and treatment of hearing loss in adults.

He has extensive experience with diagnosis and treatment of hearing loss with hearing aids, cochlear implants, and bone-anchored hearing devices across all age groups.  He has been involved in clinical research into the effects of hearing loss and treatment for hearing loss and has presented papers and posters at both national and international meetings.  He has had multiple peer-reviewed papers published within the field of audiology.  His most recently published paper explored the effects of hearing loss on balance.  He is currently collaborating with speech scientists at the University of Houston exploring how the perception of speech through hearing aids and cochlear implants directly affects speech production. He is also working with a team of engineers from the University of Houston exploring the potential for vibrotactile stimulation to help improve speech perception in people with severe to profound hearing loss. 

Helping people to communicate more effectively is a passion of Dr. Tonini and he has spent his career toward that end.   In his spare time, Dr. Tonini is an avid cyclist and has even ridden his bicycle across the United States.  He has four beautiful daughters spread across the country that he loves to be around!  He and his wife Stephanie love to cook and she is an art photographer. Together they have recently published a family cookbook focused on our family favorites!  He and his wife are active members of the Houston Choral Society, a 35 year-old auditioned community choral group in Houston that performs in Jersey Village and has recently returned from a concert performance at Carnegie Hall in New York City of Josef Haydn’s Missa in Solemnis—The Lord Nelson Mass!
