Services
The Coast Dermatology Doctors are trained in the newest and most advanced medical and surgical techniques and are at the cutting edge of cosmetic dermatology, laser, vein and cosmetic surgery. Dr. Mark Horowitz practices medicine at Coast Dermatology Medical Associates.

After completing his training at Michigan State University over 10 years ago, he has mastered some of the most advanced techniques available in dermatology and cosmetic surgery today.Dr. Mark Horowitz is an expert in general and surgical dermatology. He has advanced skills in skin cancer detection and Mohs micrographic surgery to treat large and difficult tumors of the skin.
The Dermatologists at Coast Dermatology are constantly educating their patients about skin cancer. Early skin cancer detection is critical! Please read this very important overview of skin cancer and why you may be at risk for the development of skin cancer or melanoma. During your skin exam, the doctor will examine the entire body and check for any atypical moles or lesions.
Coast Dermatology Medical Associates offers the most advanced and AFFORDABLE filler options. Restylane, Juvederm are two of the products which can be injected into the skin to lift lips, cure wrinkles & furrows and to fill cheeks which experience fat loss in middle age. Once in your skin, they create volume and stimulate collagen to improve the appearance of deep frown lines, wrinkles, and furrows for a more natural and sensuous look.
You will notice some swelling & redness for a few days. Depending on the aggressiveness of the treatment, the redness may last somewhat longer. Within days new skin replaces older sun damaged skin. Furthermore, you will continue to see improvements in your skin's texture & tone for up to nine months because of the stimulation of new collagen.
Getting rid of it can be painful. Until now the only options for removing unwanted hair were smelly hair removal creams, sharp razors, stinging wax or painful electrolysis needles. Our advanced approach to beautiful skin provides the ultimate solution. Now, men and women alike will be pleased with the results made possible by our Laser Hair Removal process.

I have been coming to Coast office for years.Lot’s of professional people working there!
Holly has done a great job on all my services!
The best thing is coming from out of State, and knowing they’ll work with me on scheduling me - by great communication from front desk to Holly
Very much appreciated!
Thank you Coast!

Busy office, but still gave me the professional and personal attention that I needed to address my skin. Fast and attentive front staff and nurse assistance asking questions in preparation of the doctor made it very smooth to get in and out under 30 mins! Dr. Kassardjian was great! Examined my skin, provided treatments/solutions, extracted what was needed and then put the band-aid on. Never have I experienced such quick professionalism and personal attention from a skilled dermatologist! I’ve been to one in Beverly Hills and l wished I found Kassardjian sooner! Thank you!

Dr K is the best. Very thorough and personable. He makes you comfortable in your own skin, which is good for a dermatologist.

The thing I like most about Coast Dermatology is that EVERYONE has a great attitude and cares about you.
I receive follow up phone calls to see if everything has gone well or if I have follow up questions. I would recommend Coast Dermatology to anyone seeking a dermatologist.

I've used Holly and Marty for various skin treatments over the years. Both provide professional and fantastic service. Love how they are helping me age gracefully. Prices are competitive with ongoing specials held throughout the year.

I write this review as a method of feedback for Dr Horowitz. I have been a long time patient of yours and see you rather infrequently. I trust your expertise and place my confidence in you when I have a dermatological issue that needs attention, that will not change. This one star is not for you. This one star is for the blind spot that you have when it comes to entrusting your office staff as the gatekeepers of your needed care. I have been truly suffering with a persistent dermatological issue that has befuddled me for the last six weeks, after the third week of hoping it would resolve on

In short: CUSTOMER SERVICE/FRONT DESK IS NOT GOOD! The doctor/nurse practitioners might be fine, but what's the point if the front desk says they will call you back (and they DON'T for three days even after follow up), they FAIL TO COMMUNICATE TO THE PHARMACY, and then you CANT GET YOUR PRESCRIPTION refilled! Not worth it, go somewhere else.

I think the staff needs to be more responsive toward emails and returning phone calls.

Just got back from a skin cancer check. The front desk workers seemed unable to understand how a mask worked. One wore her mask beneath nose and one just took hers off to fix her hair and left it off. If they are unable to follow basic cdc guidelines to keep their patients safe, I wonder what other corners they are cutting concerning my healthcare. As I left, I walked by dr Horowitz who instead of apologizing averted his eyes. After 10 years my family will be looking for a new dermatologist.

Dr Horowitz is a great doctor and his office runs very smoothly. I have never had a shorter waiting time for appointments then at his office. They usually get me in and out in 15 minutes.

I feel as though he is more conservative then other dermatologists I've been to. I have to get steroid injections for alopecia and he did a lot less injections then I've had before but my hair is still growing back.

I enjoyed my visit here! His staff is very friendly and he is a nice fellow who made me very at ease about the moles on my body. The two he removed turned out to be benign and appear to be healing well.

I absolutely loved my experience here. The whole staff was attentive and friendly. The office seems new and it is beautiful. Dr. Horowitz was super friendly and very thorough. He removed a couple of skin tags. It was quick and painless. I would recommend him and will definitely be back next year for my annual checkup.
