Mercedes – Specialized services for diabetes, thyroid cancer, and other patients have expanded in the Mid-Valley and throughout the Valley with the addition of three specialized endocrine surgeons at the UT Health RGV / Knapp Family Health Center in Mercedes and a new endocrinologist who is practicing in Weslaco.

The three new surgeons are the only members of the American Association of Endocrine Surgeons located in the Valley.  They are:

Henry Reinhart, MD, who is fellowship-trained in endocrine surgery (at the Baylor Scott & White Clinic in Temple, Texas).

The surgeons are associated with the UT Health RGV / Knapp Family Health Center in Mercedes, which recently expanded its services, as well as increasing its staff of doctors and other healthcare professionals.   The clinic is conveniently located right off Expressway 83 at the N. Mile 2 West Rd. exit in Mercedes (at 2810 W. Expressway 83, across the street from Med High and Science Academy).

The clinic –which features 18 exam rooms –is open Monday through Friday from 8 a.m. to 5 p.m. and accepts walk-in patients as well as those with appointments.  Physicians may make referrals to the three endocrine surgeons by calling the clinic at (956) 973-3531.

In addition to the clinic in Mercedes, Dr. Snyder, Dr. Reinhart, and Dr. Romero also practice out of UT Health RGV offices in Harlingen and Edinburg – offering a service which is greatly needed in the Valley but has been lacking until now.

“The message we want to get out is that we now have these services in the Valley, so patients don’t have to go elsewhere,” Dr. Snyder said. 

The types of specialized surgeries performed by the UTRGV surgeons include the following:

  • Thyroidectomy (minimally-invasive)
  • Central & Lateral Neck Lymph Node Dissections
  • Parathyroidectomy (minimally-invasive)
  • Parathyroid Exploration
  • Laparoscopic or Robotic Retroperitoneal Adrenalectomy
  • Laparoscopic, Robotic or Open Transabdominal Adrenalectomy or Pancreatectomy

In addition to these highly-specialized types of surgeries, Dr. Snyder, Dr. Reinhart, and Dr. Romero also perform the following specialized diagnostic procedures:

  • Thyroid, parathyroid, and neck ultrasound
  • Thyroid or lymph node fine needle biopsy
  • Laryngoscopy

Dr. Snyder said that the ultrasound procedure “helps us tremendously in being able to diagnose thyroid cancer at an earlier stage when it is more easily treated.” 

Conditions treated by these surgeries and procedures can include the following:

  • Thyroid cancer
  • Thyroid nodules
  • Multinodular Goiter
  • Hyperthyroidism
  • Graves’ Disease
  • Thyroiditis
  • Hyperparathyroidism
  • Hormone-producing Adrenal Tumors
  • Adrenal Cancer
  • Neuroendocrine Tumors
  • Familial Syndromes

In addition to the specialized endocrine surgery services, a new endocrinologist, Dr. Eduardo Dusty Luna, has joined a private practice in the Mid-Valley, working with Dr. Pedro McDougal and other internal medicine physicians at RGV Adult & Geriatric Medicine in Weslaco.  Originally from Edinburg, Dr. Luna is a specialist who treats patients with diabetes, thyroid problems, osteoporosis, metabolism problems, and other endocrinology conditions.  Dr. Luna is board-certified in endocrinology.  

For primary healthcare, diabetes and other Mid-Valley patients can also find family medicine physicians at the UT Health RGV / Knapp Family Health Center in Mercedes, which offers medical care for all ages under the direction of Dr. Miguel Tello, Family Medicine Physician and Associate Program Director for the Knapp / UTRGV Family Practice Residency Program.
