Dedicated & Certified Professionals

Since 1997 The Preventive Medicine Clinic has been a full-service medical clinic and general practice, providing patient care in family practice, internal medicine, surgery, dermatology, routine health maintenance and disease prevention. I specialize in state-of-the-art therapies, which includes the supplementation of bioidentical hormones: DHEA, testosterone, pregnenolone, estrogen, progesterone, melatonin, and thyroid.

Our Physicians

The program offered at the Preventive Medicine Clinics is the culmination of my own personal experience, and ongoing review of the research and latest scientific studies. As an avid fitness enthusiast, I was finding myself rapidly deteriorating and being unable to perform physically as I had in the past. I experienced aches and pains, loss of muscle and strength, decrease in endurance and lack of desire for physical activity. After replacing all of my hormones back to youthful levels, the pain and deterioration subsided. I am back to what I was years ago. Now I know why I felt so poorly for so many years!

Title: Hormone Specialist/Medical Doctor, M.D. 
Hometown: Detroit, MI 
Education: Medical School at Wayne State University
Residencies at: Sinai Hospital in Detroit in Internal Medicine, Physical Medicine and Rehabilitation


Dr. David Wilgarde has been a resident of the Coachella Valley for the past 25 years.  He is board certified in several medical specialties including internal medicine, physical medicine and rehabilitation, electrodiagnostic medicine, and a sub specialty certification in pain medicine. He has always had a special interest in bioidentical hormones and has been trained by Dr. Neal Rouzier.

Since moving to the Coachella Valley in 1992, he has served in many different roles including medical director of the acute rehabilitation unit at Desert Regional Medical Center for 12 years. He has also been involved in interventional and chronic pain management for 12 years. He also has an interest in the nonsurgical treatment of chronic spinal pain and more recently developed an interest in the newer technologies of regenerative medicine including platelet rich plasma and stem cell applications for orthopedic conditions.

Dr. Wilgarde is very excited to join Preventive Medicine Centers and offer Dr. Rouzier’s hormone replacement protocol.  His background makes him the perfect candidate to not only help our patients with hormones but he brings great insight into the aging process through his other medical expertise and experience.

"Just another day in paradise here at PMC. Since our patients have their hormones optimized, they all feel great! They feel young, energetic, and full of life. To know what PMC is doing to make this positive and dramatic change in our patients' life and to know that I had a hand in it, it is very gratifying to me. I honestly feel like there aren't enough hours in a day to help as many patients as I'd like to. This is what I went to school for. I'm just living the dream!"
