His bio says he obtained his medical degree from Universidad Autonoma de Baja California and specialised in surgery at Centro Medico de Occidente in Guadalajara 2. It says he then trained in hair transplantation at the Bosley Institute in Orlando with Dr Matt Leavitt 2. It says he later completed a hair transplant fellowship in Istanbul focused on FUE 2.

Procedures and techniques

It says there are no stitches, patients return to daily activities in about three days and can exercise hard after ten days 4. The clinic's pages describe FUE only, not strip surgery (FUT) 4. His ISHRS profile lists further procedures, including body hair and female hair restoration 6.

Pricing

Booking and aftercare

Patients can book an in-person consultation or a virtual one if they live out of town 5. The out-of-town page says travelling patients usually stay in Mexicali for about three days, arriving the day before surgery and leaving the day after 5. It says the coordinator helps arrange flights and hotels 5. The clinic is open Monday to Friday, 9am to 7pm, and Saturday morning 1.

Credentials and memberships

He is an ISHRS Full Member and joined ISHRS in 2013 6. The ISHRS listing gives the city as El Centro, but its alternate address is the clinic's plaza in Mexicali 6. The bio says he co-wrote a Spanish-language hair-loss book with Dr Shelly Friedman 2.

    male 3,500 grafts surgery 2026

    psiguy686 had about 3,500 grafts with Dr Roberto Guerrero in Mexicali and posted photos at day 6 in January 2026. He says there is decent coverage of grafts in the crown. After only nine months of finasteride and minoxidil he chose a somewhat smaller graft count to leave room for a possible second surgery next year. He gives no overall verdict, price or technique, and it is too early to judge growth.
